EA Market Testing team (EAMT)

A past project: I directed this team. It is no longer running trials, but I keep its reports, data and analysis up at the links below, and I’m still involved in research and discussion in this area.

The EA Market Testing team was a small group of researchers and practitioners interested in promoting effective altruism and effective charitable giving, and in learning more about what motivates it. As far as we knew, it was the first organized collaboration of its kind. We aimed to:

  • pull together the evidence on barriers to and facilitators of effective giving and effective action;
  • run trials and experiments, especially in large-scale real-world settings, on what works to encourage meaningful donations and commitments, both in specific cases and as general principles;
  • profile and segment audiences, to learn which people respond most to effective-giving messages and appeals;
  • share results, data and tools with practitioners and researchers.
