We collected these quotes from things they published elsewhere, and every quote links to where it was said. They have no account here and have not endorsed this site. Quotes are word for word; the short line under each one is our own restatement, not their wording. Their own site. Is this you? Claim it or ask us to remove it. Or tell us what is wrong here.

3 of Zeke Hausfather's claims fit 3 mental models. Most often: Cheaper means more, not less, Probabilistic thinking, Second-order thinking.

Models they name

Their own words name the idea.

Cheaper means more, not less

Make something cheaper to use and people use so much more of it that the total goes up (Jevons paradox).

Making AI compute cheaper per token drives enough extra usage that total AI energy consumption rises rather than falls (a Jevons paradox effect).

Probabilistic thinking

Think in odds, not certainties, and bet heavily only when the odds are clearly yours.

Used by 28 others

The historical occurrence of extreme natural events does not by itself show whether their odds have changed over time.

  1. Zeke Hausfather Climate scientist and energy systems analyst But the existence of old events tells us nothing about whether the odds are changing, and heat waves happened in 1900 too (just less frequently).

Models we see in what they say

Our reading: their claim applies the idea without naming it. The claim is theirs; filing it here is ours.

Second-order thinking

Ask "and then what?": follow a decision past its first effect to the ones that come after.

Cutting sulfur air pollution is now unmasking greenhouse-gas warming that aerosols had been offsetting.
