Thanks for the precious advice. I will take note of it. The descriptions and the results of the experiments cited in Singer's book come from the experimenters themselves. Published work, publicly available. Edit: I have talked about a "documentary" above, but it's not really a documentary, but video footage stolen from a lab doing experiments on baboons. The lab has been closed because of the videos. The fuss is unnecessary with you sir [1]. [1] https://en.wikipedia.org/wiki/Unnecessary_Fuss https://en.wikipedia.org/wiki/Unnecessary_Fuss
