What is the "EA Market Testing Team"?

We aim to promote awareness and understanding of the core ideas of Effective Altruism (EA), and "to make giving effectively and significantly a cultural norm." We consider marketing campaigns, charitable appeals, events, and public communication, working both with our partner organizations and in independent surveys and trials. We want to improve the design and messaging of organizations like Giving What We Can and 80000 Hours to improve their outreach methods and maximize their impact. Measuring and testing 'what works and when': While helping these organizations do marketing and communication we are also testing and analyzing this rigorously. We help run and track careful data collection and rigorous controlled trials. We robustly analyze the results to better understand which approaches tend to have a more positive impactda. Communication: We track, organize, and share what we have learned with the EA community, building and organizing resources and a knowledge base. This will address questions such as:
We strive to be transparent. We want to report and share our data, procedures, code, and evidence without overselling the results.

We believe this is the first organized collaboration of its kind. We aim to...

  • Coalesce our understanding and evidence on barriers and facilitators of effective altruism, effective giving, and effective action
  • Run a broad set of high-powered trials (large samples, high-stake real-world contexts, substantial differences between conditions)
    • ... to gather evidence on what works best to promote meaningful actions in specific cases,
    • ... while aiming at generalizable principles and approaches
  • Do profiling, survey, and segmentation activities and trials, building evidence on 'which types of people' are most responsive to effective giving messages and appeals
  • Share our results, data, and tools, with the relevant EA and research-interested communities. This will enable more and better outreach, promotion, testing, and insight.

What is our mission? Updating...

As EAMT has progressed, we have encouraged others to do work and pursue initiatives in the 'space' of studying EA messaging, and marketing EA and effective giving. We hope that the resources we have provided, and the connections we have made have contributed to this. As the space changes, the EAMT mission, scope, and activities are adjusting as well.
We are moving towards a heightened focus on
  1. 1.
    Advising, proposing, and helping to design and coordinate experiments, trials, and initiatives.
  2. 2.
    Transparent presentation of the results, rigorous statistical analysis
  3. 3.
    Synthesizing, sharing, and communicating this knowledge and skills base
This work provides substantial public goods, whose benefit is shared among the partner organizations and the EA community.
  • Giving What We Can 'Bequests' (a project we have encouraged and advised)
  • Effective Giving Collaboration and Summit

Note that we cannot publicly share details of ongoing and upcoming trials. We aim to share the results when it is possible. We aim to integrate shareable aspects of this private doc.

"The EA Market Testing team has been very helpful in helping us to pursue our mission of creating a world where giving effectively and significantly is a cultural norm. They have helped us at each stage along the process of ideation through to analysis so that we can base our outreach activities on sound theory and strong evidence. This is at a particularly important time as we have been scaling up our marketing activities to reach and engage new audiences with effective giving and the ideas of effective altruism more broadly. We look forward to an ongoing collaboration with EAMT so that we can continue to iterate and increase our impact.”
It’s been extremely useful to hear what others in EA, individuals and orgs are doing and sharing learnings between us. I hope that we can develop a set of tactics that we know successfully convert people and get them more involved in EA. A reliable set of best practices for marketing EA would be a great outcome.
"As a quick testimonial relevant to this stage of the process, David [Reinstein]'s support has been critical to the Charity Elections team's development of plans for marketing and program evaluation. Our first ad campaign was particularly impactful, generating one click to the Charity Elections page on the Giving What We Can website per $0.01 spent on the campaign. We will continue to incorporate his advice into our advertising to spread awareness of the Charity Elections program among high school students and teachers."
