Part-Time Genius

We’re closing out this week of curiosity with our good pals Josh and Chuck (and super producer Jeri!) from Stuff You Should Know. It’s a wide-ranging, brain-tickling conversation that touches on everything from childhood obsessions to SYSK behind-the-scenes stories to the shocking truth about off-mic personas. Plus: Everyone tries to figure out which Muppet they are, for some reason.

Today Will and Mango explore the science of curiosity at different ages: how school can help (or hurt) kids’ curiosity, why middle age may make you less curious, and what we know about babies’ curiosity, even though they can’t fill out questionnaires. Plus: A conversation with a researcher who made a surprising discovery about elderly people, and expert tips for practicing curiosity, whether you’re 1 or 100.

Today we’re taking a break from human curiosity and turning our attention to other animals. What makes hummingbirds explore different flowers? Are we to blame for rats’ curiosity?

Day 3 listener activity: Grab an assortment of objects and present them ...

Where did the saying “curiosity killed the cat” come from, and is it just a way for the rich and powerful to oppress everyone else? (Hint: yes.) Today on the show, Will and Mango take a look at curiosity’s checkered history: from the Middle Ages (when it was considered a threat to society) to the 17th century (when it became downright trendy) to today (when we can Google anything we want). 

Day 2 listener act...

Every day this week, we’re exploring a different aspect of curiosity—you know, the thing that makes you listen to this show. We’re starting off by discovering what happens in our brains when we experience curiosity, why some things make us curious and others don’t, how a lack of novelty can lead to pretty strange behavior, and how all of this ties in to our willingness to buy oat milk.

There are lots of ways we could tell you about the art of secret messaging: we could waggle a blanket, grab a bucket of gallnuts and iron supplements, flutter our fans, or tattoo some information on a hapless intern’s scalp. But that’s pretty complicated, so Mango and Gabe made a podcast about it instead.
