Tim Harford here. I'm the host of Cautionary Tales.

We've teamed up with a couple of other great shows from the Pushkin Network

to bring you a special episode all about mistakes and what we can learn from them.

They said swish the ketamine around in your mouth and then spit it out.

And I swish it around in my mouth for about 30 seconds and then I swallowed it.

Listen to the episode on Cautionary Tales, available wherever you get your podcasts.

Hello, Side Doorables, happy fall.

As we don our sweaters and crunch through the leaves of the National Mall,

the question on everyone's lips is, will this be the best season of Side Door yet?

To shake the magic eight ball, signs point to yes.

That's right. Side Door is back. Season 12, baby. And we've got a whole trove of Smithsonian stories for you.

We'll dive in with a good old-fashioned mystery, hidden inside one of Abraham Lincoln's most prized possessions.

People say don't judge a book by its cover.

I think you don't judge a watch by its face because faces can come off.

And you never know what they're going to hide. Then it's off to upstate New York in search of the real Uncle Sam with some unexpected company along the way. On a scale of creepy to not creepy,

where does this four-foot doll rank? It only scares you when you're going into the gallery and you forget that it's sitting in a chair with his legs crossed and go, oh.

We'll take flight with one of the Wright brothers' lesser-known siblings.

Wilburn-Orville Wright invented the airplane. The question is, could they have done that without Catherine Wright?

Plus, archivist sleuths, dark matter, and a life-saving scientific accident in the form of

mold juice. Yummy. We'll have music, dancing, history, mystery,

science, and more from the world's largest museum and research complex.

Side Door Season 12 is out next week.
