Barriers to effective giving: evidence synthesis

In this open, dynamic document (with Nick Fitz, Janek Kretschmer and Luke Arundel), we:

  • make the case that there’s a puzzle: people give a lot, but rarely to the most effective causes;
  • lay out the possible barriers to effective giving, and how they connect;
  • critically assess the general and specific evidence, as groundwork for meta-analysis;
  • suggest tools and approaches for overcoming these barriers. This fed into the (now past) EA Market Testing team’s trials.

The most detailed part is the synthesis of how donors respond to analytical “effectiveness information”: Effective giving: responses to analytical effectiveness information.
