Thinking in Bets: Making Smarter Decisions When You Don't Have All the Facts

by Annie Duke

Surfers have more than twenty terms to describe different kinds of waves. The reason is that the type of wave, the way it breaks, the direction it’s coming from, the bottom depth, etc., create differing challenges for surfers. There are closeouts (waves that break all at once) and double-ups (a type of wave created when two waves meet to form one wave) and reforms (a wave that will break, then die down, then break again). Non-surfers just call all of these “waves.” On rare occasions when we non-surfers need to be more specific, we just add a lot of extra words. Those extra words don’t cost us much because it doesn’t come up very often—maybe never. But for people involved in specialized activities, it’s worth it to be able to communicate a complex concept in a single word that laypeople would need lengthy phrases to convey. Having a nuanced, precise vocabulary is what jargon is all about.
