STEVE INSKEEP, HOST:

When we have a question about something embarrassing or deeply personal, many of us don't turn to a parent or a friend, but to our computers: We ask Google our questions.

As millions of us look for answers to questions, or things to buy, or places to meet friends, our searches produce a map of our collective hopes, fears, and desires.

Many people tend to push frightening realities out of mind rather than face them head-on. That's especially true when it comes to the terrifying event that no one can escape — death. Psychologist Sheldon Solomon says people may suppress conscious thoughts about their mortality, but unconscious ones still seep through.

Why do you work? Popular wisdom says your answer depends on what your job is.

But psychologist Amy Wrzesniewski at Yale University finds it may have more to do with how we think about our work.

"Fake news" is a phrase that may seem specific to our particular moment and time in American history.

But Columbia University Professor Andie Tucher says fake news is deeply rooted in American journalism.

In 1690, British officials forced the first newspaper in North America to shut down after it fabricated information. Nineteenth-century newspapers often didn't agree on basic facts. In covering a lurid murder in 1836, two major papers in New York City offered wildly differing perspectives on the case.

We just can't let go of some decisions. We replay them in our head and imagine alternate endings.

These sorts of looping mental videos are called counterfactuals. Northwestern University Professor Neal Roese says there's real value to wondering "if only."

"Counterfactual thoughts are generally useful for us in terms of providing a set of options that we might act upon in the future," he says. "This can lead to improvement. It can lead to learning from experience."

Throughout history, people have sought to create utopias. Perfect societies free of defects.

Of course, not everyone shares the same vision for a utopia. Different people have different priorities. But the wishes of those with power and prestige almost always take precedence.

On this episode of the Hidden Brain radio show, we tell the story of overzealous American scientists who believed creating a utopia for some would eventually lead to utopia for all. This is a story of people who believed they were doing the enlightened thing, even if it traumatized others.

Here's how it usually goes: You're working from home and you dial in to a conference call for the morning meeting. Everyone is cheerfully talking around the table. You can't believe what a good time everyone seems to be having, talking about nothing.

Then someone starts to laugh. And then everyone's laughing. Except for you, silently listening on the phone. You're not even cracking a smile, forget about laughing. You wonder, when did this conversation become so hilarious? What am I missing?

Many people start exploring their sexuality in college. The lessons they learn about intimacy and attraction during these years lay a foundation for the rest of their lives.

"I have students who have had sex many times drunk but have never held someone's hand," says Occidental University sociologist Lisa Wade.
