If you had the power to ensure all EAs understood 1 concept back to front. What would it be?
Only one concept per answer.
Please do not read this and feel obliged to understand all these. I don't want obligation.
I am asking because I might create a test to see how well EAs do know these concepts then see if I can get content for concepts people don't know. This is meant to make things easier not harder.
Distribution of cost-effectiveness feels like one of the most important concepts from the EA community. The attitude that, for a given goal that you have, some ways of achieving that goal will be massively more cost-effective than others is an assumption that underlies a lot of cause comparisons, and the value of doing such comparisons at all.
