0:00Good learning happens through making mistakes.

0:02Just seeing something many times doesn't mean you'll remember it well.

0:05You've seen the Apple logo so many times, of course you know all the features, but then when you quiz people and test them, and I do this in my class, people aren't sure is the bite on the left or the right-hand side, is there a stem or a leaf?

0:18The best way to remember something is to, again, failures.

0:21I'll have you draw it without looking at it, and you struggle and wait, is it on the left or right?

0:25Is it a stem or a leaf?

0:26And you're starting to question all of these things.

0:28Then when you look at the logo again, you're going to engage in better learning than if you hadn't done that errorful kind of trial beforehand.

0:35Welcome to the Huberman Lab Podcast, where we discuss science and science-based tools for everyday life.
