Thanks Ivan, this is really excellent and interesting. It makes me update towards believing that book giveaways are impactful. With that said, you probably have some sample bias (i.e., the people who responded to the survey are probably different from those who didn’t in meaningful ways). That probably means that the impacts are somewhat smaller than the survey suggests.
If you are still running the survey, it would be interesting to give people who ask for the free book the option to complete a presurvey so you have some pre and post measures. Also, I think that you might have forgotten to link to Appendix B.
I agree about the sample bias. Which is part of the reason why I think the data from actual donations is relevant—rather than relying on respondents self-reported figures.
Implementing a presurvey is one of the top improvements to action—as I do expect that to help a lot. If you have any particular suggestions for useful pre/​post measures, I’d love to hear them.
Appendix B is contained within the Appendices (Google Doc).
