It goes far beyond the familiar warning about objects in our rearview mirrors, by now. I hate to tell you this, but all sorts of objects, everywhere, might not be anything like they appear.

I’ve been reading a book that my friend Ron recommended, called The Drunkard’s Walk: How Randomness Rules Our Lives, by Leonard Mlodinow. By a few pages in, I loved it so much, I wanted to weep. Give me a book about geeky-fascinating, blow-your-mind science stuff, and I’m a goner.

The book is about (and do NOT run away here – I’m getting ready to tell you some funky-cool things) probability theory, chance, and how psychological illusions cause us to misjudge the world around us – not because we are stupid or gullible, but because these illusions are so powerful.

I think of it this way: our complex psychological and emotional makeup constantly interferes with our ability to analyze data and use pure reasoning. But also, we exist in both a microscopic world and a macro universe, the scopes of which are virtually impossible for most of us to grasp.

Our elegant brains are simply hard-wired to misinterpret data. Here are a few examples.

Our perceptions of probability and cause & effect are skewed.

We tend to think, in our own lives and in the world at large, that an event is either more or less likely to occur because it has (or has not) happened recently. (We think: “Her luck has run out…” “He is due…”) This is the same reasoning behind the hiring and firing of CEO’s or studio heads, when they’ve had a run of several good or bad years/movies.

We – and executive boards, and recruiting agents, and on and on – reason that results are based on performance…isn’t this what we’ve been taught, all our lives? But, as has been mathematically proven (and the book goes into great detail on this), much of what happens in the world is the result of randomness – the result of what is called “Bernoulli’s theorem” (after a 17^th-century mathematician) or “the law of large numbers.”

Of course, Kobe Bryant’s talent allows him to perform much better in the NBA than, say, my neighbor Sandra would. But Kobe’s individual performance from game to game, or season to season, or throughout his career, is due almost exclusively to chance, and not to fluctuations in his abilities. This might sound like hooey, but it’s a scientific fact.

Success, as it turns out, really is most often a matter of repetition. Bad news for the exceptionally talented of this world. Fantastic news for the exceptionally dogged.

Our perceptions of relevance, and our interpretation of statistics, are skewed.

During the O.J. Simpson murder trial, it was an accepted fact that Nicole Brown had been previously battered by O.J. So one of the arguments that the defense team pulled out was this: Of the 4 million women who are domestically battered each year, only about 1 in 2,500 are killed by their partners.

This was a true fact. It was a very convincing argument, to the jury. And on an intuitive level, it appeared to be completely and totally relevant to the O.J. case.

But it wasn’t.

Why not? Well, the previous statistic dealt with women who are NOT killed – and Nicole most definitely had been killed. The relevant statistic (and one the prosecution failed to bring up) was this: of all the battered women in the U.S. who are killed (and Nicole was part of this category), 90 percent of them are killed by their abuser.

The first (irrelevant) statistic created such a powerful illusion, it helped convince the jury to acquit a double-murder defendant.

Our perception of logic is skewed.

Here’s a fun example of the way our brains resist reality, from The Drunkard’s Walk.

Let’s say you know that someone has twins, and you wish to determine the likelihood that both children are girls. If you don’t know the gender of either child, then the chance that they are both girls is 1 in 4. Sounds logical, right?

Moving along, let’s say you find out that at least one of the children is a girl. Now the chance of them both being girls increases to 1 in 3. (Still sounds right.)

However, if you are told that one of the children is a girl named Florida (!), then the chances of them both being girls increases to 1 in 2.

Whoa, whoa, whoa, back that train up.

How can this be? How can one girl’s strange-sounding name affect the odds on the gender of the other child?

And yet, as Mlodinow painstakingly proves over a few pages, this outlandish statement is an absolute fact. In this example (and in so many others, throughout the book), my own instincts for mathematical reasoning completely failed me.

Moving away from The Drunkard’s Walk…

Our perceptions of space and time are skewed.

As we’ve all heard, we (and everything else in the universe) are not moving in a linear way through space and time, from point A to point B; instead we are moving through four dimensional space-time, a concept that even Stephen Hawking calls “impossible to visualize.”

When we look at the sun, we are seeing it in the past, as it existed eight minutes ago – but since everything we perceive comes to us via signals (which require time to travel), even as you read these words, you are looking at your computer screen as it existed in the past (infinitesimally so, of course.)

We’re not just “lost in space,” peeps – we’re lost in time.

Our perception of reality might even be skewed!

The more you start thinking about all these problems with perception, the more widespread you realize they are. Indeed, this recent article from Discover Magazine suggests that our entire universe might be – are you ready for this? – a giant hologram.

This theory will never be proved in our lifetime, of course, but it certainly dovetails nicely with the Christian belief that this world is but a pale twin of another dimension, the “real” reality that is our eternal destination.

(And may I humbly submit: if you are someone who rejects the concept of God and/or Christian beliefs because they seem too far-fetched, too “hocus-pocus” for practical people, then you haven’t been paying attention to the world of science in the last decade. From space exploration to theoretical physics and everything in between, the physical laws of this universe are far wackier than anyone ever imagined. You can still have personal objections to Faith, if you like – but you really can no longer reject it on intellectual grounds.)

*********

I’ve barely scratched the surface here – but it sure would be nice if this information made us think twice, the next time we want to dig in our heels about our points of view on something. Because chances are very good that our perception is flawed – that there are factors we haven’t considered, or aren’t even aware of.

If mankind understood this concept, it would deliver a death sentence to arrogance of every sort – intellectual, spiritual, societal.

And that would be a very, very good thing.
