Data, Data Everywhere…

Leave a reply

In The Rime of the Ancient Mariner, poet Samuel Taylor Coleridge lamented “Water, water everywhere, nor any drop to drink.” There seems to be no better way to describe our situation today with regard to information. We sail upon a vast ocean of data and yet we die of thirst. Indeed, we are too often deluged by great waves of facts that batter us relentlessly to and fro upon treacherous seas of data.

It feels particularly disconcerting for me to write this article. In my book, Belief in Science and the Science of Belief (see here), I promote the importance of elevating facts above beliefs. After all, facts should reflect reality. They should be the basis upon which truth is known. Today however, data seems to be used far more effectively to support beliefs, fantasies, and lies than it is used to reveal truths. Indeed, those who wish to sell us nonsense don’t often bother to invoke the bible or faith anymore – they invoke their own “facts” instead.

One reason that facts have become the new champions of beliefs and cons is the sheer amount of it. We now have so much data that one can mine anything they want from the endless mountains of the stuff that we have produced. Misrepresented facts can now be dredged up to fabricate lies far easier than spinning magical stories of gods and devils.

Nowhere is this new perversion of facts more true than in politics. Today politicians like Donald Trump incessantly cite completely misleading facts to support their beliefs and positions and to outright lie. Even if the majority of people do not believe their “trumped up” facts, they nevertheless conclude that all facts are suspect and that no facts can be trusted. This tangibly undermines the level of rational thinking of our entire culture and leaves us without any sound basis for making good decisions as a society.

In his excellent Op-Ed (see here), William Davies points out that “they [facts] seem to be losing their ability to support consensus.” According to Davies, there is clear agreement that “We have entered an age of post-truth politics.” This new age of bullshit is fueled not by assertions of faith, but by assertions of facts. As Davies further points out, “Rather than sit coolly outside the fray of political argument, facts are now one of the main rhetorical weapons within it.”

So facts have become the new bullshit. We claim to care about facts, but only because, as with the bible, we can always find something in them to support our beliefs and prejudices and self-interest. Our abundance of data seems to be only serving to diminish and undervalue it; to make it increasingly vulnerable to manipulation, misrepresentation, and lies by half-truth. The sheer volume of it makes it far more difficult to say anything with certainty without some other bit of data seeming to contradict it.

And this perversion and misuse of facts is not just true in politics but has become the new normal in all walks of life. All too often journalists and pundits do not pursue facts to reveal truth, but rather invoke them to advocate for opposing sides of an issue. This makes great theatre, but does little to advance the important questions that we face. It instigates and perpetuates conflict rather than help reach a sound fact-based consensus.

Even scientists, our gatekeepers and guardians of fact, all too often emphasize only those facts that advocate for their positions rather than serving the far greater goal of advancing science as a quest for truth.

Abandoning facts is simply not an option. Allowing the manipulators to turn all fact-based thinking into rationalization games and data manipulation exercises is not an option because without sound facts good decisions simply cannot be made. If we allow facts to be coopted by magical thinkers, by self-serving politicians, or even by well-meaning advocates, we might as well put the psychic hotline staff in charge of our fates.

What is the answer? We must reclaim facts. We must become smarter consumers of facts who are no more likely to be fooled by the bogus facts cited by manipulative politicians or corporations any more than we are by laughably ambiguous bible citations and interpretations. We must learn to recognize valid data and sound conclusions amidst all the cherry-picking and false claims. We must learn to treasure and respect fairly presented facts as diamonds amongst all the heaps of rubble and fool’s gold that we have to sift through every day.

Our overabundance of data should make us value – and demand – sound analysis and conclusions based on that data all that much more.

 

An Alternate View of Automation

1 Reply

People are rightfully concerned about robotics and automation costing us jobs. A report issued by the World Economic Forum early this year (see here) projected that 5.1 million jobs will be lost by 2020 across the 15 leading economies. This loss is attributed to “labor market changes” which includes robotics and automation. But for sake of this discussion, let’s blame robots for all 5.1 million lost jobs.

Tim Worstall, unsurprisingly a contributor to Forbes Magazine, puts this number into a less gloomy light (see here). He points out that while this 5.1 million figure sounds huge, it is out of a total labor pool of about 1.68 billion workers. This translates to a projected unemployment increase of only 0.3%, well below the noise level in these projections. Coincidentally, I wrote a recent article about how statistics are often reported in a very misleading fashion (see here).

RobotOf course job loss is not the only concern or even the major concern. The number of people forced to retrain and change jobs is not included in these projections. Certainly jobs always evolve, but periods of rapid and widespread job disruption are nevertheless painful and difficult. Even those who can transition through the major upheaval being caused by automation and globalization may find themselves forced into jobs they no longer love. More importantly those new jobs may pay far less than the old ones. This loss of standard of living must be mitigated through responsible corporate and governmental policies.

But I contend that human nature will win out in the end over automation. Automation ostensibly promises greater efficiency but this is simply counter to human nature. I’ve written in the past about the tendency of really smart people to come up with astoundingly convoluted solutions to simple problems (see here). Given that tendency, smart people will naturally direct automation toward enabling more complicated systems rather than merely replacing humans in existing ones.

Our tendency toward complication is synergistic with another characteristic of human nature – empire building. In my book on business management (see here), I talk at length about how inefficiency is ironically desirable in the workplace. Contrary to typical intuition, deadwood workers are assets while high-performers are obstacles to the inherent goal of managers to expand their head counts and their budgets. Therefore, automation will be unavoidably applied in such a way as to increase human headcounts by increasing complexity rather than decreasing headcounts through greater efficiency.

Here’s just one example. Ten years ago I designed and developed a customer management system for my employer for negligible cost. Ongoing support costs were also negligible. But this simple, robust, and powerful system would never be replicated today. Now there are new “automation” frameworks available designed to make this easier. But, despite all the promised efficiencies of moving to an automation platform, no jobs were lost in this transition. Quite the opposite, implementing this new system required literally hundreds of people and tens of millions of dollars, not to mention a huge explosion in personnel required to support it moving forward. The benefits are very debatable, but the costs are not.

In this as in many cases, the automation that one might fear would cut jobs proves to dramatically increase the number of jobs needed to support far more complex and fragile systems. Automation, when implemented in accordance with our human nature and self-interest, is likely to create many, many new jobs overall. While this won’t help with the disruption problem, loosing net jobs overall is not likely to be a problem.

Human nature, and the benefits that inefficiency and complexity offer for empire-building, effectively protects us from a future where automation takes over all our jobs.

 

Studies Show That…

One of the most compelling arguments in support of religion is the totally pragmatic one. What does it matter if religion is false, if god is totally made up, if faith is only a placebo effect, or even if it’s all ultimately just a scam to separate you from your hard-earned money? In the end isn’t all that matters that it makes you happier and more successful?

Reporters and opinion writers propagate this pragmatic justification of religion every day. It is actually difficult to get through any newspaper issue without encountering yet another article or op-ed touting the benefits of religion and faith. Here is an example of the typical kind of happiness claims put out there most every day in popular media:

Research suggests that children who attend church perform better in school, divorce less as adults and commit fewer crimes. Regular church attendees even exhibit less racial prejudice than their nonreligious peers. (see here).

happinessThese articles invariably cite scientific studies and statistics to support their claims. But those claims frequently go far beyond study design or the conclusions made by the scientists involved.

There are many ways that studies are misused by advocates to advance their causes or market their products. So we must all be very savvy when we see broad, sweeping conclusions being supported by narrow scientific studies, particularly by social science studies.

To help you to recognize these manipulations, following are some of the typical falsehoods and distortions used by advocates to misrepresent science or to promote bad science.

Failing to Mention the Negatives
Studies show that chocolate supplies 11 grams of fiber! Wow, maybe we should all eat chocolate to get our fiber! But to get that 11 grams of fiber from chocolate you have to consume a whopping 600 calories. Likewise, studies tout selected admirable ethical qualities of religious people, but fail to mention other studies that show, for example, that religious people are far more likely to support torture, guns, violence, and drone attacks.

Failing to Mention Better Alternatives
Another way advocates misuse studies is by failing to mention far better alternatives. For example, the chocolate industry fails to mention that practically any fruit, vegetable, or grain is a far healthier source of fiber. That may not be their responsibility, but if they are implying that you should eat chocolate in order to get your fiber, they are lying. Likewise, advocates often tout the morality of religious people, implying that religion is the only way to achieve these values. But you don’t need to consume 600 calories to get your fiber and you do not need religion along with all its negative characteristics to be a good person.

Failing to Quantify the Benefits
Advocates will often claim a benefit without quantifying it, thereby giving a false impression of how important it is. For example, religion advocates may cite studies showing that fewer religious people go to prison, without mentioning that this difference is inconsequentially tiny.

Misrepresenting Statistics
Advocates often misrepresent statistics. If they are trying to magnify a small difference they report it as a percentage or ratio. If they are trying to exaggerate a tiny difference in a huge population, they cite the numerical difference.  For example, religion advocates might claim that “secular people are twice as likely to commit suicide as religious ones.” Sounds fantastic right? But this could very well mean that out of a population of 10,000 people, 1 religious person committed suicide and 2 non-religious people committed suicide. Not quite as alarmingly persuasive when presented that way.

Using Bad Indicators
In epidemiology, an indicator is a specific test that can be used to measure a more general condition. But a bad indicator tells one little or nothing about the general trait being evaluated. For example, religious advocates typically conclude that believers are “happier” based upon highly questionable measurements such as divorce rate which have little to do with happiness. As we all know, married people can be far more miserable than divorced ones.

Failing to Prove Causation
Most clinical studies are observational, or association studies. That is, they simply show that two variables are both observed in or associated with a given population. This is valuable information. But proving that those two variables are directly related to each other is quite difficult. Proving causality between one and the other is even more difficult. Even if two things seem to be related, they may be indirectly associated through some third thing called a confounding factor. For example, a study may show that church-goers cheat less on their spouses. That is merely an association. But advocates use that observed association to claim that church attendance promotes ethical behavior even though the researchers themselves never made that claim. However, it may well be that church attendance and marital fidelity are not directly related at all, let alone that church attendance causes fidelity as advocates claim. The most we could say based on the research is that, for whatever reason, people who go to church are also more likely to be people who have fewer affairs. Maybe the reality is that unattractive people tend to go to church in a desperate and futile attempt to start an affair. Attractiveness may the just one confounding factor here. That we cannot determine or even imagine what the confounding factors may be is not proof of causality.

Failing to Consider Reporting Bias
Many of the narrow social studies used to make sweeping claims rely upon self-reporting. However, self-reporting is incredibly unreliable. People intentionally or unintentionally report all kinds of things in all kinds of ways for all kinds of reasons. For example, men are likely to brag about their infidelity while women are likely to conceal it. Self-reports are poor measures of the relative level of infidelity between the sexes. Likewise, religious people are deeply invested in the fiction that religion makes them happier and are very likely to report that they are even if they are totally miserable.

Failure to Mention Study Limitations
Years ago, upon reading commonly cited statistics that “98% of women report incidents of sexual abuse,” radio host Dr. Laura Schlessigner did what a good consumer of information should do. On-air, she called the scientist who conducted the study being referenced to support this claim. The researcher was eager to express her frustration with all of the advocacy groups citing her research without mentioning that her study narrowly targeted an extremely at-risk population. Dr. Laura then called the head of one of those women’s advocacy groups employing this scare-tactic and asked her why she knowingly misrepresented this research. When confronted, the head of the organization stood firm, saying that anything is justified if it raises awareness of real issues faced by women.

Choosing the Wrong Measurement
Even if we could measure happiness, it should not be assumed that happiness is the best or only goal. Believing that  global warming is a hoax probably does make one sleep sounder. Allowing your kids to eat pizza at every meal will probably result in fewer observed food-related tantrums. But clearly these measures of happiness do not justify accepting those positions. Likewise with religion.

Selective Skepticism
We tend to do pretty good at being skeptical about things we disagree with. But when it’s something we’re predispositioned to like and want, like chocolate or religion, we tend to set all skepticism aside and whole-heartedly embrace any arguments in favor, no matter how much of a stretch they may be. The happiness-arguments supporting religion are definitely one area in which our society demonstrates far too little critical scrutiny, as evidenced by the huge number of happiness claims repeated in major publications with virtually no skeptical analysis.

Baby With the Bath Water
Please, please, please don’t conclude from this that you can never trust social studies and that these studies never have any value at all. Association studies are very valuable. We need to know when things are observed together in a given population. However, you should be a smart consumer of these studies and understand the ways that advocates misuse study results to contrive claims that advance their cause. This is particularly important when we are predisposed to believe those claims. When in doubt, look past the claims made by advocates or even by seemingly objective “science reporters” and read the typically more careful and restrained conclusions reported by the scientists who conducted the studies. With the Internet at our fingertips today that is not usually very difficult to do.

Our Curious Public Mood Swings

Leave a reply

PolicyMood

This is a fascinating and revealing chart illustrating our curious public mood swings. It was produced by Larry Bartels (see here) using data compiled by James Stimson (see here). It measures the “policy mood” of the country since 1950. The higher the score, the more conservative was public opinion at that particular point in time.

Stinson derived this policy mood index from responses to a wide range of public policy surveys. Since it does not rely upon self-identification as liberal or conservative, it is arguably a more nuanced and accurate measure of where public attitudes fall on the liberal-conservative spectrum.

The most obvious thing to note here are the dramatic swings. Clearly public attitudes about major issues are not as fixed as we might imagine. Over the past 65 years public opinion has swung up and down by almost 20 points. Clearly public sentiment can be swayed significantly.

The most interesting thing about these swings is revealed when you refer to the Administration timeline that Bartels added to the x-axis. If you study this a bit you’ll undoubtedly start to scratch your head in confusion. Under each Democrat administration the country became more conservative, and under each Conservative administration the country became more liberal. This is entirely counter-intuitive and immensely important.

The nation became dramatically more liberal during the Eisenhower years. Ike was moderately conservative overall but staunchly conservative on economic issues. It became slightly more conservative during the moderately liberal Kennedy/Johnson era but shifted far toward the conservative extreme during the very liberal Carter years. Similarly, during the extremely conservative Reagan era, public sentiment shot back down again toward the liberal end of the spectrum. Under Clinton, the public then became more conservative and after a year or two of George Bush became more liberal again. Finally, under the very liberal President Obama, we have become dramatically more conservative.

The next observation may or may not be significant, but the swing has been between 30 and 50 on this scale of conservatism. I can’t imagine what kind of views it would require to earn a 100% rating on this scale, but for what it’s worth public opinion has remained solidly on the liberal side of the spectrum. This seems to defy the popular meme that America is a “near Right” country. It suggests we are actually (still) a “near Left” country.

But that may not last if trends continue. Although this chart bounces up and down, there is still a clear upward best fit line. This supports the long-term trend toward conversativism reported independently by other sources. Essentially each President since Eisenhower has rated as more conservative. More specifically, each Republican President has been more conservative than the previous Republican President and each Democrat President has been more conservative than the previous Democrat President. This reinforces the observation that despite these swings, the Conservatives succeed year after year in moving the “center” ever farther toward the Right.

So what conclusions can we draw from these data? First, it isn’t true that we are intractably divided and cannot change. Clearly a very significant fraction of us can be moved a substantial amount in one direction or the other. Next, we are perhaps overall more liberal than the Right would like to have us believe. However, we are trending ever more conservative and that is never likely to reverse as long as liberals keep voting for the “lesser of two evils” who is still ever more conservative than his or her predecessor.

Finally, as Bartels pointed out in his article, Presidents do not actually succeed in shifting public opinion their direction. The data rather show that the public tends to recoil reliably away from the President in their attitudes. Paradoxically and counter-intuitively, these data suggest that the fastest way to shift public sentiment toward the liberal end would be to elect a highly conservative President. And the best way to reverse the long-term trend toward conservatism may be to allow our “lesser of two evils” Democratic candidates to lose.

 

 

 

The Anatomy of Thought

Mind-uploading is the fictional process by which a person’s consciousness is transferred into some inanimate object. In fantasy stories this is typically accomplished using magic. By casting some arcane spell, the person’s consciousness is transferred into a physical talisman – or it might just float around in the ether in disembodied spirit form.

Mind_switcherIn science fiction, this kind of magic is routinely accomplished by means of technology. Upgraded hair-dryers transfer the person’s consciousness into a computer or some external storage unit. There it is retained until  it can be transferred back to the original host or into some new person or device. This science fiction mainstay goes back at least to the 1951 novel “Izzard and the Membrane” by Walter M. Miller Jr.

In some of these stories, the disembodied consciousness retains awareness within the computer or within whatever golem it has been placed. Sometimes the consciousness is downloaded into a new host body. It might inhabit a recently dead body but other times it might take over a living host or even swap bodies with another consciousness. Fictional stories involving technology being used for a variety mind-downloading and body-swapping scenarios or possessions go back at least to the book to “Vice Versa” written by Thomas Anstey Guthrie in 1982.

The 2009 movie “Avatar” depicts of all sorts of sophisticated technological mind-uploading, remote consciousness-control, and even the mystical downloading of consciousness into a new body. In this and innumerable other science fiction, fantasy, and horror plots, minds are portrayed as things that can be removed and swapped out given sufficiently advanced magic or technology – like a heart or liver. This is depicted so often in fact that it seems like some routine medical procedure that must be right around the technological corner at a Body-Swap™ franchise near you.

One reason this idea seems so believable to us because it is so similar to installing new software into your computer. But the computer analogy fails here. Brains are not analogous to computers in this regard and consciousness is not analogous to a computer program. Our hardware and software are not independent. Our hardware is our software. Our thoughts are literally our anatomy.

It might be a better analogy to rather think of our brains as non-programmable analog computers in which the thinking is performed by specific electronic circuits designed to perform that logic. The logic is not programmed into the circuits, the logic is the circuitry itself. Our thoughts are not programmed into our brains, our thoughts are produced by our neural circuitry. Obviously  our thinking does change over time, but this is a physical re-linking and re-weighting of our neural connections, not the inhabitation of some separable, independent consciousness within our brains.

I allow that we might conceivably copy our consciousness into a computer, but it would only be a mapped translation programmed to emulate our thought patterns. And as far-fetched as that is, downloading our consciousness into another brain is infinitely more far-fetched. That would require rewiring the target brain, that is, changing its physical microstructure. Maybe there is some scientific plausibility to that, like a magnet aligning all the particles of iron along magnetic ley lines. But it’s incredibly unlikely. We’d essentially have to scan all the connections in the subject’s brain and then physically realign all the neurons in the target brain in exactly the same way and tune the strength of all the connections identically.

And even if we did that, there are lots of nuanced effects that would still introduce differences. Our body chemistry and external drugs influence how these neurons fire. In fact, it’s likely that even if our brain were physically transplanted into a new host body, subtle differences in the environment of the new body would affect us in unanticipatable ways, influencing the very thoughts and emotions that make us – us.

Yet our fantasy imagining of consciousness as an independent abstraction not only persists but largely dominates our thinking. Even the most modern intellectuals tend to be locked into at least an implicit assumption of a mind-body dualism. René Descartes was a key figure in bringing scientific and philosophical credibility to what is fundamentally a religious fantasy concocted to make religion seem plausible (see here).

For religious thinkers, a mind-body duality MUST exist in order for there to be an after-life. In order for religious fantasies to seem reasonable, the soul (essentially just our disembodied mind) must be independent and independently viable outside the body. For many, the mind or soul is bestowed by god and is the uniquely holy and human thing that we have that lesser species do not. For them, the mind has to be separable to support their fantasy of God-given uniqueness from the rest of the animal kingdom. A unified mind-body greatly undermines their case for creationism, human divinity, and an afterlife.

So this illusory assumption of dualism is propagated by familiar computer analogies, by ubiquitous fantasy and science fiction, by horror ghost stories, and by our dominant religious and new age thinking. But this dualistic pseudoscience leads to many false and misleading ideas about how our brains work. That in turn results leads us to a great deal of mistaken thinking about a broad and diverse range of questions and precludes our ability to even imagine more realistic answers to those questions.

One harm this idea does is to provide a circular, self-fulfilling basis for belief in the supernatural. If we accept the assumption that our mind is independent, that then demands some kind of mystical explanation. But this dualistic thinking hinders our understanding of many non-religious questions as well. How do newborns fresh out of the womb or the egg know what to do? How can thoughts be inherited? How can a child be born gay? The answer to all these questions become quite simple if you shed your mistaken assumption of dualism. We all start with an inherited brain structure which is the same as to say that we are all born with thoughts and emotions and personalities.

When you truly internalize that the mind and body are one and the same, that our thoughts arise purely from our brain micro-structure and our unique body chemistry, new and far simpler solutions and perspectives open up for a wide range of otherwise perplexing and vexing social, scientific, and metaphysical questions.

Someone smarter than me could write a fascinating book about all the ways that this fantasy of an independent consciousness leads us to false conclusions and inhibits our ability to consider real answers to important questions. But if you simply become aware of this false assumption of duality, you will find that you’ll naturally start to look at a wide range of questions in far more satisfying and logically self-consistent ways.

 

 

If Only I Had a Photographic Memory!

Few of us probably remember the 1968 B-film cult classic Barbarella. In that fantasy story the naively buxom Barbarella battled the sadistic Durand-Durand and the evilly beautiful Dark Tyrant. One notable character in this sex romp was the blind angel Pygar. The white-winged angel befriends Barbarella but is then kidnapped and cruelly tortured by the Dark Tyrant.

pygarIn the climax of the film, with the city exploding around them, Pygar swoops down and rescues both Barbarella and the Dark Tyrant, flying off with one woman in each arm. Barbarella looks up at his angelic face, confused, and says “Pygar, why did you save her, after all the terrible things she did to you?” Pygar answers serenely, “Angels have no memory.”

It’s an interesting thought. Angels have no memory. Perhaps only without memory can one really be an angel. Perhaps memory makes us just too bitter, too angry, to resentful, too hurt to be truly forgiving. Perhaps it just isn’t possible to remember every hurt one caused you and still fully forgive them. Perhaps those memories must be sacrificed to gain your wings.

There is data to support this premise.  Researches have looked at individuals on both extremes of memory. They have studied those rare individuals who have no long-term memory – who cannot recall anything beyond very recent events. They have compared those individuals to those equally rare individuals with nearly perfect recall, people who can exactly remember almost every incident, no matter how unremarkable, that they ever experienced.

When you compare these two groups, you see clear differences. Those with impaired long-term memory tend to be quite happy and contented while those with exceptional long-term memory tend to be quite unhappy, depressed, angry, and even suicidal. Apparently, having perfect memory takes its toll. One cannot forget every slight, every insult, every disappointment, and every disillusionment. Such unselective memories make one quite unhappy. Not having memories can be a blessing.

On the other hand, those with perfect memories tend to be excellent networkers. They recall every birthday, every anniversary, and every name. So they tend to have lots of social support that can offset their hurtful memories. Those with poor memories on the other hand tend to have few social contact and fewer friends. The cost of happiness may be loneliness and the loss of social connectivity. Are they then still happy? Kind of a sad internal contradiction.

Don’t hire an angel to become your salesperson and don’t expect them to win celebrity Jeopardy.

Thankfully most of us aren’t angels with no memory and we aren’t elephants who never forget a slight and stomp their trainer into a bloody pulp years later. We lie in the broad middle of the spectrum. I am certainly no angel but I think I lie off toward the bad memory end of the continuum. I have a terrible memory but am pretty free from regrets and grudges. But I’m also quite bad at social networking as I am hopeless at remembering things, let alone birthdays and anniversaries. I’ve wisely perhaps stayed away from professions that rely upon memory and entered instead into a career where things change quickly, where continually looking up current information is an advantage.

Many of us imagine that perfect memory would be kind of a cool superpower but that such recall is just not really possible. But it is clearly possible and evolution is wise enough not to give us what we think we want. Sometimes less is better. We could have much better smell or hearing or taste, for example, and some people do and it makes them painfully miserable. Longer lifespans are apparently possible as well, but evolution knows that longer lifespans are not actually a good thing for the individual or for the species.

Evolution has given us the balance of memory we need to make us both functional and happy. If technology eventually lets us override evolution on this, we may regret being burdened with all those painful best-forgotten memories.

What Aliens Look Like

3 Replies

We aren’t likely to ever meet an alien. As I argued in a previous post, although it is a statistical certainty that alien life must exist, the laws of physics simply make it implausibly improbable that they could ever visit us or we them (see here). The most likely way we might learn what aliens once looked like would be if we happen to pick up an interstellar message in a bottle from some distant ancient civilization, their own version of Voyager with candid snapshots and videos from back home.

But we can make educated guesses based on the fundamental design constraints of the elemental building blocks and physical processes that apply throughout the universe. For example, intelligent aliens must have a lower and upper size limit based on fundamental constraints of molecular dimensions and gravity.

We can similarly surmise much more. For example, any intelligent alien species is likely to be highly mobile – for that they require large bursts of energy – for that they require a fluid chemical transfer system – for that they require a variable speed pump controlled by a central nervous system that adjusts the amplitude and frequency of pumping based upon a large amount of sensor data – and that control mechanism would have to be autonomic so that the pumping controller is highly responsive and unaffected by their state of consciousness.

So, intelligent alien species are likely to have circulatory and nervous systems that are mechanically and functionally quite similar to our own. For vision they are likely to have two sensors placed up high for optimum line of sight and depth perception. They are likely to be similarly similar in the design of their other major systems. In short, after looking past superficial differences, alien life would almost certainly be quite familiar to human physicians and biologists.

It would be foolishly egotistical to imagine that all alien life will be exactly like us and the other species present on Earth. Certainly there would be dramatic and astounding variations that we cannot begin to imagine. But it would also be equally foolish to imagine that the bulk of species in the universe would not evolve following much the same processes with much the same results as life here. A human exobiologist could almost certainly be trained to understand, diagnose, and treat almost any form of alien life.

hortaIn Star Trek, after Doctor McCoy got over his initial revulsion (You expect me to treat that thing Jim?!?), he was able to patch up even the exotically alien silicon-based Horta with some simple spackle compound.

But apart from exceptions like the Horta, Star Trek and most every science fiction universe depicts very human-like aliens. This implicit assumption of similarity is made mostly so that alien creatures will be relatable and to make them playable by human actors with minimal make-up and costumes.

AlienBut we create human-like creatures even when there are no technical constraints. The astoundingly terrifying alien created by HR Giger is remarkably human-like with 2 arms, 2 legs, a head, a tail, a mouth, and so on. Despite having acid for blood, his alien follows the evolutionary design model of a human quite closely. It is likely not the case, as many imagine, that such alien depictions represent an unimaginative human conceit and lack of imagination. Rather, it is likely that such physics-defying aliens are actually much more fanciful than evolution is mechanically capable of producing – on any planet.

And let me be clear. Its unfathomably unlikely that any alien could remotely pass as human and walk amongst us undetected – that’s purely a movie fancy as unrealistic as aliens with acid for blood that can eat through feet of metal. However, they will be biologically similar in function if not form. They will not have any superpowers or godlike abilities that defy basic chemistry and physics because they can not. If they can fly they will need wings. And as any dolphin can tell you, there is a fundamental limit to how far they could advance without appendages that allow them to manipulate their environment.

Even many of us who are wise enough to understand that god cannot exist are still far too willing to remain agnostic in insisting that there might be aliens out there with what would effectively be godlike powers.

If my hypothesis of fundamental similarity is true, and I suggest that it must be more true than not, it should encourage us that we’re not actually missing out on as much as we might imagine because we are effectively bed-ridden here on Earth. Aliens would be marvelous to see, but evolution has offered us a pretty representative sampling of the range of life typically found in the universe.

Unless a message in a bottle lands on our Earthly beaches, we’re unlikely to ever know for sure how typical we are. Even then, that would give us only one more example of life. But we can make some pretty good assumptions about the nature of life in the universe without direct experience. And it is likely that the range of actual life in the universe is no where near as wide as our unconstrained imaginations.

So what do aliens look like? Probably a lot more like us than we might imagine.

There are no end to the crazy stories that go around. My uncle was saved from a bear by Bigfoot and has the scars to prove it. This guy on TV was molested by aliens – his story was checked out by a team of scientists. My grandmother was kissed by her dead husband and she wouldn’t make that kind of thing up. The Virgin Mary appeared to a homeless guy in the Bronx who had no reason to lie. Forty-Seven cows mysteriously died in Iowa after a Haitian witch doctor got snubbed at a truck stop and cursed the town – couldn’t be coincidence. Everyone knows that old house is haunted by a woman who was murdered by her lover in the 40’s. That was the day my dead pet returned to save my life.

Given that there is absolutely no possibility that any of these stories are actually true, one has to wonder how they ever get started in the first place. We even have to wonder whether they might have some element of truth if only because there seems to be no conceivable way that such tales could ever get started if there wasn’t some truth to them.

But get started they do. While I cannot give you every particular origin story, I can relate to you one real example to illustrate how these things get started.

One summer during college I was rooming with my longtime buddy Steve. As I walked back to our place late one sweltering night in Wisconsin, I was feeling particularly bored and fanciful. The nighttime shadows helped work my imagination into a receptive frame of mind and when I walked past the window of a local craft shop I was struck by these hand-crafted dolls on display in the window. Now like many people I do admit to being generally spooked by dolls and as I looked at this one particularly creepy looking doll bathed in old-time street lamps, I got inspired to mischief.

I took off running (I had been a track and cross-country runner) but got myself plenty winded by the time I reached our building. I stumbled, intentionally falling and crashing up the stairway and pounded on our door with desperate urgency. Steve opened the door to the sight of me in very convincing panic-stricken terror. I rushed into the room and I made him drag my terrifying story from me. I told him that I had been walking past this store and noticed this doll and suddenly I felt an eerie presence, like some evil spirit, and without warning this doll leapt at the window and clawed at me. I panicked and ran all the way back to the room, the entire time feeling like some malevolent demon was chasing me.

Steve’s reaction was all I could have hoped for. Though frightened he valiantly insisted that we go back that very night to face this demon. I reluctantly agreed to show him where the store was but refused to get closer than the end of the block. I watched down the street as Steve heroically inched forward, craning his neck tentatively to glimpse this demon-doll. Suddenly he jerked, bolted, almost got hit by a passing car as he stumbled into the street, ran all the way back to and past me, shouting breathlessly “I saw it dude! It was the most hideous thing I’ve ever seen!!”

RamonaAudleyYup, in retrospect I should have owned up to my prank right then and there. But Steve was so pumped up I decided to tell him in the morning. By the next morning I had forgotten all about it, and anyway Steve had already left to go somewhere before I woke up. I was reminded of my folly when Steve returned and proudly related how he had gone to the craft shop, paranormal investigator like, to sleuth out the origins of this demon doll. The owner told him that by the greatest of coincidences, the doll-maker, a lady by the name of Ramona Audley (pictured right) happened to be paying a visit at that very same moment. Steve politely confronted Ramona and asked her whether she knew that she was crafting possessed dolls. Ramona apparently nearly went into a terrified state of shock and I was later to learn that the dolls were removed from the store window that very day (Ramona, I did you wrong and I’m so sorry).

It gets worse. When Steve told me what he had done I was mortified. That poor Ramona Audley! I never intended to frighten her or the shop owner! But how could I tell Steve the truth of my prank now that he had done this? I settled for hoping that this whole debacle would just blow over.

Needless to say it did not just blow over. It took on a life of its own like Godzilla emerging from the ocean to wrack havoc. For the next several decades, whenever Steve introduced me at any kind of gathering, he insisted that I tell the doll story. Of course I would refuse, feigning intentionally ambiguous reluctance. But Steve would invariably take over and tell the story on my behalf, prefacing it with a lengthy introduction about how he would never believe this story from anyone else in the entire world except from me. My credibility and sanity and integrity are (were) apparently just that irreproachable.

If you dear reader could have admitted to making up this story prior to this you are a better person than me.  And to make matters even worse, Steve is a naturally gregarious guy who became a minor celebrity with a sizable fan following. Who knows how many people he has told this story to who have in turn related it to many other people, who all swear that they were assured that this story came from an impeachable source. Every year that went by while I hoped that the story would be finally forgotten, every time I failed to disavow it, the myth became that much more indestructible.

My dolls truly had become demons. A few years ago I agreed to be interviewed for a video documentary about my friend Steve. To my horror and chagrin Steve had prompted the documentarian to ask me about the “Doll Story,” which he did, on camera. The story had finally advanced to a line I could not cross and I admitted to my prank on camera rather than perpetuate it any further.

Even after that public admission, I still live in perpetual dread of seeing this bogus story reenacted on the History or Science channel. Lots of people are probably more willing to believe that I lied about it not happening rather than believe that I simply made it up as a silly impulsive prank. After all, what kind of inconceivably horrible person would make up such a story? Umm, yes, that would be me.

And that, my friends, is how these things get started.

There is Always a Trick

Leave a reply

We are all tempted at times to be open-minded about  supernatural claims. Indeed, it can seem narrow-minded to dismiss the seemingly inexplicable stories related by sensible, credible people we trust. Sometimes we ourselves experience things that seem to defy any rational scientific explanation. These experiences seem to prove that there must indeed be more to the universe than reason can explain. It can be hard to push back on the logic that if one cannot offer proof of a scientific explanation then one must accept a supernatural one.

Whenever you are tempted to entertain belief in something supernatural or paranormal, just remember one invariably true thing as a given: there is always a trick.

DougHenningI’m reminded of a formative event back in the 1970’s when I went to a performance by the late magician Doug Henning. Between making live tigers disappear, he would walk out to the edge of the stage and do slight-of-hand magic. In one such interlude, he held up a newspaper and showed it to us, turning each page so we would remember the layout. He then proceeded to methodically tear it into smaller and smaller pieces. As he did so he kept a great dialog going:

You think you see it tearing, you think you hear the sound of paper ripping apart, you think you see me holding two separate pieces. All your senses are convinced that I’m tearing up this paper, but I am not.

He continued to rip the paper into shreds and stack up the pieces, in full view, into a little folded-up pile. Then he began to unfold it and show us the full newspaper perfectly in-tact once more. As he paged through the “reassembled” newspaper, he continued his narration:

There is no magic, this is a simple trick. Obviously I could not actually have torn up the paper. But the trick is the magic and the magic is the trick.

Doug Henning was brilliantly messing with the audiences minds there, but what I learned from him is that there is always a trick. No matter how inexplicable something might seem, you only need to know the trick. But moreover, you can be still amazed by the trick and, even knowing it is only a trick, it can still amaze and astound you every bit as much as true magic. In fact, knowing there is no magic, nothing supernatural, no god, does not need to make the world one bit less exciting and inspiring. Quite the opposite. You can feel even more amazed knowing that the real explanation must actually be so clever, so masterfully executed, that one imagines that only some supernatural story could possibly explain it. The trick is SO amazing that it is easier for us to consider some magical explanation rather then the real mundane one.

Years later I watched one of those shows on television that exposes magical tricks. In this episode, they showed the magician and his gorgeous assistants make a mini-sub disappear right on stage. It was astoundingly, compellingly real. Surely there could be no conceivable way that such a feat could be accomplished without true supernatural intervention.

But after the commercial break they simply showed the exact same performance shot from a rear angle. It suddenly seemed stupidly crude and simple, so pathetically obvious that one could not imagine anyone actually trying to fool anyone with it, let alone anyone actually being fooled by it.

It was incredibly disappointing to see that trick exposed. It was ruined forever. I vowed never again to watch any explanation of magic. I want to be amazed. I want to experience that awe and wonder over and over. But I know there is always a trick. All it takes is to move the camera ever so slightly and it becomes ridiculously obvious.

But  the “good” magic that magicians or fantasy novelists or artists offer us does not extend similar benign merit and value to the “bad” magic of hucksters, con-artists, priests, rabbis, imams, televangelists, psychics, and other charlatans. These promoters of the supernatural do not simply entertain and inspire. They tangibly damage our capacity to reason and lead us to unreasonably dangerous or exploitive attitudes and behaviors. And, before you ask, the answer is no. There is no equivalence between our choice to suspend our disbelief in an entertaining magic trick or ghost movie and our choice to suspend disbelief about the idea that a psychic can predict the future or that some god influences the present. We simply choose not to ruin the illusion by pulling back the curtain to expose the trick. We do not believe or tell others that stage magic is true and we certainly do not base life decisions upon a conviction that you really can saw a woman in half.

And it is often the smartest of us who are most susceptible and gullible with regard to magical thinking, and most likely to influence others. I recall when at the height of the “crop circle” craze, one network interviewed a “scientist” who had investigated the circles. He proclaimed that he had studied the markings extensively and could see no earthly method by which they could have been produced. Therefore, he concluded in stentorian tones, they could only have been created by an extraterrestrial (supernatural) force.

Of course the actual method that those guys who later came forward used was as silly as making the mini-sub disappear. But the arrogance and ego of that scientist led him to conclude that if HE could not see the trick, the only explanation must be a supernatural one. Even Sir Isaac Newton, one of humanity’s most brilliant thinkers, was compromised by similar hubris when he assumed that if HE, Sir Isaac Newton, could not explain the stability of planetary orbits, it can only mean that God must intervene.

So remember, there is always a trick, and let that certain knowledge make you more confidently skeptical regarding religious and supernatural claims, confident enough even to simply reject them out-of-hand. But yet be no less awed and inspired by the perfectly explainable but nevertheless amazing magic in the world.

For elaboration of this and further discussions about facts and belief, I refer you to my book “Belief in Science and the Science of Belief” (found here).

 

Our MacLean Revival

MacLean“A small dusty man in a small dusty room. That’s how I’d always remember him, just a small dusty man in a small dusty room.”

Grabs your interest doesn’t it? That was the opening line of The Dark Crusader by Alistair MacLean. I first devoured this and other adventure novels by MacLean while in High School back in the 70’s. Recently, my wife and I have taken to reading his books out loud to each other and – even in this high-tech era of blockbuster 3D adventure movies – MacLean’s novels continue to be singularly engaging adventures. We can’t wait to take up where we left off reading and we spend much of our time between sessions discussing the implications of whatever bits and pieces MacLean has revealed thus far.

Beyond the marvelous storytelling, MacLean was technically and aesthetically the most gifted author I have ever read. One part of what he achieved with seemingly effortless nonchalance was to deliver the catchiest openings ever. From them his stories flowed, briskly gushing and careening, like rivers of words through the coldly entrancing arctic landscape that was his favored setting. So daunting are his prose, that just taking on the challenge of reading them out-loud has made us both infinitely more fluid and polished readers.

His writing characteristically flows on in methodical rambling, like a symphony put to words, each sentence sometimes strung together over the course of a page or more, leaving the reader as breathless and exhilarated as after a hard swim, only to snatch a quick breath before diving into the next incoming wave.

“My red rose has turned to white.”

His plot lines are so tight, so carefully constructed with milimetric attention to detail, that when his protagonist laments in the prologue of Fear is the Key that his red rose has turned to white, you presage that MacLean will inevitably return to that same powerful imagery in his epilogue.

While his general storytelling elements recur in every book, MacLean’s writing does not feel overly formulaic. Within his general adventure fiction structure, MacLean paints distinctive characters and settings for each book. Unlike other authors, he doesn’t have one main character, no James Bond or Jason Bourne, but he does invariably feature smart but fallible male protagonists who face opponents who are far smarter and much less fallible in their utter ruthlessness.

MacLean also knew how to create a strong supporting cast with whom you engage every bit as much as his protagonist. In fact, I think that one of the reasons I went into chemistry was the inspiring moment in Night Without End when that frail little chemist Theodore Mahler used his knowledge to save the desperate survivors of the plane crash from the grasp of icy death in the deadly and merciless arctic. In that same book, the climax was not when the main hero saved the day, but when boxer Johnny Zagaro, hands rendered useless by crippling frostbite, finally had his inevitable bloody, brutal battle on the ice with the cold-blooded Nick Corazzini.

In MacLean’s novels, nature is invariably the most implacable enemy of all – whether it be the frigid clutch of the arctic, the unforgiving cliffs of Navarone, or torrential storms of the Adriatic. His books are typically light on romance, and in fact MacLean isn’t averse to nipping a budding romance with tragedy. Another distinctive quirk of MacLean is that he does tend to use certain words over and over again. My wife and I play a game to see who will be the first to encounter “milimetric” or “threnody” or “St. Vitus’s Dance” when we take turns reading a book. And be assured that in most every book, teeth will be lost, frostbite will claim fingers, and cigarettes will be burned in liberal quantities.

I find MacLean’s writing particularly noteworthy in how unlike conventional writing it is. He routinely devotes little more than a few short sentences to masterfully describe people and settings, for he needs no more than that, so powerfully potent are his descriptions. But then he is just as likely to go on in excruciating detail about how to wire the detonator for an explosive bobby trap. You have the feeling that he really did have the whole thing wired up and even tested in his office next to his typewriter. In fact all of his writing conveys a particularly strong sense that the author has actually been there and done that. MacLean’s actual background as a seaman and torpedo operator in the Royal Navy is keenly evident in all his writing.

Beyond his astounding gift for writing, I also admire the tone, the characteristic humanity of his works. Throughout his yarns, he weaves in his passion for humanity, for peace amidst cold-war intrigue and violence. Indeed, it was his clearly heretical defense of people, particularly Communists, and his cosmopolitan skepticism toward politics and religion, that caused such negative backlash to his book “The Last Frontier.” It was bold and provocative writing back in 1959, too much for the times he lived in.

“Jansci spoke of himself not at all, and of his organization and its methods of operation only where necessary … He talked instead of people … of their hopes and fears and terrors of this world. He talked of peace, of his hope for the world, of his conviction that that peace would ultimately come for the world if only one good man in a thousand worked for it … He spoke of Communists and non-Communists, and of the distinctions between them that existed only in the tiny minds of men, of the intolerance and the infinite littleness of minds that knew beyond question that all men were inescapably different by virtue of their births and beliefs, their creeds and religions, and that the God that said that every man was the brother of the next man was really a poor judge of these things. He spoke of the tragedies of the creed that knew beyond doubt that theirs was the only way that was the right way, of the religious sects that usurped the gates of heaven against all comers … for there were no gates anyway.”

Though now somewhat anachronistic and dated by patronizing 50’s attitudes toward women (even though his women definitely show great strength) MacLean’s work is still nevertheless as fresh and timelessly potent as the day it was written. My wife and I rather dread the day that we finish up our Alistair MacLean revival. There is very little in the marketplace of literary ideas that match up for us. As just one example, we tried reading Jack Reacher and having been so spoiled by the mastery of MacLean we find the writing and the characters as flat and empty and devoid of life as a cardboard cutout. Are there other authors as gifted as MacLean? Certainly, but it is a very short list indeed.

“A small dusty man in a small dusty room. That’s how I’d always remember him, just a small dusty man in a small dusty room.”
