A  Compound interest (CI) is calculated using A = P(1 + r)^n, where P = principal, r = rate & n = no. of periods; e.g. $1,000 @ 7% p.a. for 10 yrs yields approx. $1,967.

B  Here's the idea behind compound interest. You earn interest on your money... and then you earn interest on that interest. Say you put in one thousand dollars, at seven percent a year. After ten years, without adding a cent, you'd have almost two thousand dollars. Your money nearly doubled... just by sitting still.

A  [hesitant, unsure] So, um... we kind of built this app? It's, like, a study thing... and we think it could maybe help some students remember stuff a bit better. If that makes sense?

B  [calm, confident, unhurried] Students forget most of what they study within a week. Schools know this. They answer it with more homework, and that doesn't work. So we built Loop. It quizzes you at the exact moment you're about to forget. Four hundred students used it this term. Their test scores went up eleven percent. We're asking for ten pilot schools. Give us one term.

Welcome back to The Study Lab. Today's topic is the forgetting curve. In eighteen eighty-five, the psychologist Hermann Ebbinghaus tested his own memory and found that new information is lost quickly unless it is reviewed. The solution is spaced repetition: self-quizzing after one day, three days, and one week.

B  two hosts, generated together
JESS  [warm] Welcome back to The Study Lab. I'm Jess.
MARK  And I'm Mark. [chuckles] Jess, confession time. I read an entire chapter last night, and this morning... gone. Nothing.
JESS  [laughs] Okay, that's not you being bad at studying. That's the forgetting curve.
MARK  The forgetting what?
JESS  The forgetting curve. Back in eighteen eighty-five, a psychologist named Hermann Ebbinghaus tested his own memory, and he found we lose new information fast. Really fast... unless we go back to it.
MARK  [curious] So how do I go back to it without rereading the whole chapter?
JESS  You don't reread. You quiz yourself. Tomorrow, then in three days, then in a week.
MARK  Wait— that's it? Three short quizzes?
JESS  [playfully] That's it. It's called spaced repetition, and it beats cramming almost every time.
MARK  [sighs] I wish someone had told me that in high school.

Hook
You studied for three hours last night. [short pause] So why is most of it gone this morning?

Tension
[matter-of-fact] Most people think the answer is to study longer. Read it again. Highlight more. Stay up later.

Turn
[warm] It isn't. [short pause] The problem is not how long you study. It's when you come back to it.

Proof, why
[clear, unhurried] In eighteen eighty-five, a psychologist named Hermann Ebbinghaus tested his own memory. He learned lists of nonsense words, then measured how fast they faded. Most of the loss came in the first day. But each time he went back and learned them again, it took less time, and the fading slowed down.

Proof, how
[encouraging] So here is what to do tonight. Close the book. Write down everything you remember. Check what you missed. Then do the same thing tomorrow, in three days, and in a week.

Close
[slowly, with a smile] Don't study longer. Come back sooner.
