Belief, disbelief and uncertainty generate
different neural pathways in the brain

During an early episode of the über-pyrotechnic television series MythBusters, Adam Savage was busted by the camera crew for misremembering his predictions of the probability of an axle being ripped out of a car, à la American Graffiti. When confronted with the unmistakable video evidence of his error, Adam sardonically rejoined: “I reject your reality and substitute my own.” (continue reading…)

Evolutionary economics explains why irrational
financial choices were once rational

Since 99 percent our evolutionary history was spent as hunter-gatherers living in small bands of a few dozen to a few hundred people, we evolved a psychology not always well equipped to reason our way around the modern world. What may seem like irrational behavior today may have actually been rational a hundred thousand years ago. Without an evolutionary perspective, the assumptions of Homo economicus — that “Economic Man” is rational, self-maximizing, and efficient in making choices — make no sense. Take economic profit versus psychological fairness as an example. (continue reading…)

Evolution and economics are both examples
of a larger mysterious phenomenon

Living along the Orioco River that borders Brazil and Venezuela are the Yanomamö people, hunter-gatherers whose average annual income has been estimated at the equivalent of $90 per person per year. Living along the Hudson River that borders New York State and New Jersey are the Manhattan people, consumer- traders whose average annual income has been estimated at $36,000 per person per year. That dramatic difference of 400 times, however, pales in comparison to the differences in Stock Keeping Units (SKUs, a retail measure of the number of types of products available), which has been estimated at 300 for the Yanomamö and 10 billion for the Manhattans, a difference of 33 million times!

Journal article explanations of how science
works often differ from the actual process

According to 55 percent of 350,000 people from 70 countries who participated online in Richard Wiseman’s Laugh Lab experiment (discussed in last month’s column), this is the world’s funniest joke:

Two hunters are out in the woods when one of them collapses. He doesn’t seem to be breathing, and his eyes are glazed. The other guy whips out his phone and calls the emergency services. He gasps, “My friend is dead! What can I do?” The operator says, “Calm down. I can help. First, let’s make sure he’s dead.” There is a silence, then a shot is heard. Back on the phone, the guy says, “Okay, now what?”

How the curious science of the oddities
of everyday life yields new insights

Using an index finger, trace the capital letter Q on your forehead. Which way did the tail of the Q slant?

What an odd thing to ask someone to do. Exploring weird things and why people believe them, however, is what I do for a living. Coming at science from the margins allows us to make an illuminating contrast between the normal and the paranormal, the natural and the supernatural, and the anomalous and the usual. The master at putting uncanny things to the experimental test — the man I call the Mythbuster of Magical Thinking — is University of Hertfordshire psychologist Richard Wiseman. His new book, Quirkology: How We Discover the Big Truths in Small Things (Basic, 2007), presents the results of his numerous (and often hilarious) experiments on all matters peculiar.
