ARI SHAPIRO, HOST:

Let's say you're at a party or walking down the street and suddenly out of a sea of passing faces one of them lights up. Someone is looking right at you, waving, saying hello, they're happy to see you and you have no idea who this person is. Some of us are really good at recognizing faces. Others of us are not. To explain why, here's our social science correspondent Shankar Vedantam from NPR's Hidden Brain podcast.

SHANKAR VEDANTAM, BYLINE: Marty Doerschlag has a super power that I would love to have. He can remember a face forever.

The election of Donald Trump came as a shock to many Americans, but perhaps most of all to those in the business of calling elections. The pollsters on both the left and the right had confidently predicted Hillary Clinton would walk away with the race. They got it wrong. But one man did not: Allan Lichtman.

On Sept. 23, Lichtman, a historian at American University, declared that Trump would win, and he stuck by that call through the tumultuous final weeks of the campaign.

It's no secret that this presidential campaign season has been tense, with disagreement and rancor even louder than usual.

Fewer than 1 in 5 members of Congress are women. At Fortune 500 companies, fewer than 1 in 20 CEOs are women. And if you look at all the presidents of the United States through Barack Obama, what are the odds of having 44 presidents who are all men?

If men and women had an equal shot at the White House, the odds of this happening just by chance are about 1 in 18 trillion.

You know, when we think about disparities in American education, we think about things like race, gender. There is also income, which is one of the most persistent disparities. Children from more affluent families do better in school on average than children from poor families. And there's new social science research exploring why this is the case. To talk about it, I'm joined by NPR social science correspondent Shankar Vedantam. Hey, Shankar.

SHANKAR VEDANTAM, BYLINE: Hi, David.

You know, from Wall Street to Las Vegas, a lot of people take chances. And there's now some new social science research looking at how the mood of a gambler can change the way he thinks about the risk. NPR's Shankar Vedantam is here to explain this. Hey, Shankar.
