I am sorry I was not able to attend the 2016 Effective Animal Advocacy Research Symposium which was held at Princeton University on November 12-13th. Interestingly, I note that this was organised and co-sponsored by Animal Charity Evaluators, so this ties in nicely with our last blog on Effective Altruism. Overviews of the conference presentations can be read on the event website. We were pleased to see that there were contributions on social science and movement building from Zachary Groff and Ling-Ann Hsiung, which we believe to be a crucial aspect of lasting social change.
