Engineers do research, researchers engineer

Practise spending a fixed compute budget on the experiment that answers the question.

Example

Research judgment

“An area of human comparative advantage, for now, is research taste and judgment, including choosing which problems matter, which results to trust, and when an approach is a dead end.”

Research taste stays with people

Practise checking what a benchmark gain still supports after an overlap check.

Example

“Similarly, once Claude can run experiments, the question shifts towards “Which of these experiments is worth running?”

Which experiments are worth running

Practise checking what a benchmark gain still supports after an overlap check.

Example

“We find that hill-climbing on only one benchmark does not lead to a generalizable result.”

One benchmark is not enough

Practise checking what a benchmark gain still supports after an overlap check.

Example

“The held-out benchmark tests generalization: it is never shown to the AAR”

Hold out a benchmark

Practise checking what a benchmark gain still supports after an overlap check.

How to prepare

“You can look things up—just be comfortable with basic syntax and standard libraries so it doesn’t eat up your time.”
