So we know that a picture speaks a thousand words, but NPR's Shankar Vedantam is here to tell us how it also gives us really strong impressions of people that we can't seem to shake. Hi, Shankar.

SHANKAR VEDANTAM, BYLINE: Hi, Rachel.

STEVE INSKEEP, HOST:

We heard a lot during the presidential campaign about the wage gap, the fact that women often earn less than men for the same kinds of work. Hillary Clinton pushed that issue, and she lost. But it remains a reality in many people's lives.

"Clean up this mess!"

This is a command you've probably given or received in your life. Perhaps in the last day, or even the last hour.

To many of us, the desire to bring order to chaos – to tidy up our kids' toys, organize an overstuffed closet, or rake the leaves covering the lawn – can be nearly irresistible. And it's a desire that extends to other aspects of our lives: Managers tell employees to get organized. Politicians are elected on promises to clean up Washington. And so on.

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