Spoiler alerts are sacred.
We plunge our fingers into our ears when a friend divulges details about a TV series we have yet to finish. We avoid articles that discuss important plot points of a movie we haven't gotten around to watching.
Sometimes, this 'no spoilers' mentality leaks in other parts of our lives. We avoid getting an important medical test done, fearing bad results. We turn off the news when the headlines make us upset, even though the information is pertinent to us. According to economist Joshua Tasoff, this behavior is irrational.
"A person should never avoid information, because information can never hurt a decision."
On this week's Hidden Brain, we discuss information aversion, a concept commonly called the ostrich effect.
Hidden Brain is hosted by Shankar Vedantam and produced by Rhaina Cohen, Maggie Penman, Jennifer Schmidt, Parth Shah, Renee Klahr, and Gabriela Saldivia. Our supervising producer is Tara Boyle.

You won’t find a paywall here. Come as often as you like — we’re not counting. You’ve found a like-minded tribe that cherishes what a free press stands for. If you can spend another couple of minutes making a pledge of as little as $5, you’ll feel like a superhero defending democracy for less than the cost of a month of Netflix.
