Confirmation bias is our tendency to seek evidence that supports our beliefs and that confirms our assumptions — when we could just as well seek disconfirmation of those beliefs and assumptions instead.

It feels like we are doing the hard work — doing the research required to build good beliefs — but since we can so easily find that confirmation, when we stop searching at those moments when we think we have made sense of the world, we can grow ever more wrong over time.

This is such a prevalent feature of human cognition, that until recently a second phenomenon has been hidden in plain sight. Recent research suggests that something called desirability bias may be just as prevalent in our thinking.

Since our past beliefs and future desires usually match up, the desirability of an outcome is often twisted into our pursuit of confirmation like a single psychological braid — and here’s the thing: When future desires and past beliefs are incongruent, desire usually wins out.

Is psychology too WEIRD? That’s what this episode’s guest, psychologist Steven J. Heine suggested when he and his colleagues published a paper showing that psychology wasn’t the study of the human mind, but the study of one kind of human mind, the sort generated by the brains that happen to be conveniently located near the places where research is usually conducted — those of North American college undergraduates.

They called them the WEIRDest people in the world, short for Western, Education, Industrial, Rich, and Democratic — the kind of people who make up less than 15 percent of the world’s population.

In this episode, you’ll learn why it took psychology so long to figure out it was studying outliers, and what it means for the future of the science.

In psychology, they call it naive realism, the tendency to believe that the other side is wrong because they are misinformed, that if they knew what you knew, they would change their minds to match yours.

According to Lee Ross, co-author of the new book, The Wisest One in the Room, this is the default position most humans take when processing a political opinion. When confronted with people who disagree, you tend to assume there must be a rational explanation. What we don’t think, however, is maybe WE are the ones who are wrong. We never go into the debate hoping to be enlightened, only to crush our opponents.

Listen in this episode as legendary psychologist Lee Ross explains how to identify, avoid, and combat this most pernicious of cognitive mistakes.

Psychology is working on the hardest problems in all of science. Physics, astronomy, geology — those are easy, by comparison. Understanding consciousness, willpower, ideology, social change – there’s a larger-than-Large-Hadron-Collider level of difficulty to each one of these, but since these are more relatable ideas than quarks and bosons and mass coronal ejections — this a science about our minds and selves — it’s easier to create eye-catching headlines and, well, to make podcasts about them.

This is the problem. Because the system for distributing the findings of science is based on publication within journals, which themselves are often depend on the interest of the general media, all the biases that come with that system and media consumption in general are now causing the sciences that are most interesting to the public to get tainted by that interest.

The cyberpunks, the Founding Fathers, the 19th Century philosophers, and the Enlightenment thinkers — they each envisioned a perfect democracy powered by a constant multimedia psychedelic freakout in which all information was free, decentralized, democratized, and easy to access.

In each era, the dream was the same: A public life for the average citizen that was no longer limited by any kind of information deficit; a life augmented by instant and full access to all the information anyone could ever want. On top of that, they imagined the end of gatekeepers, the public fully able to choose what went into their minds.
