Everything you know has an expiration date

In April, 2010 — 13 years ago this month — we did a segment on the concept of the “mesofact,” a certain kind of data point that feels fixed even though it’s actually always slowly changing. (I’d add a link to that show, but our archive doesn’t actually go back that far.) And we’ve gone back to the idea every now and again ever since. Think about things like the world population or the Periodic Table of the Elements. Or think about our understanding of the health and nutritional value of red wine. Or coffee. Or how Brussels sprouts are supposed to taste. Or what dinosaurs are supposed to look like. This hour, an update on a bunch of mesofacts that we’d probably all lost track of, including the myth of the alpha wolf and the misconceptions around white gloves and antique books.
