David and Tamler welcome Paul Bloom back to the show for a definitive ranking of classic psychology experiments. Will the shocking results of the Milgram studies earn him a posthumous 'S' ranking? How far will Zimbardo fall? Is the Stroop effect a super effect? Did you see the Gorilla in these notes? Which is more plausible: that we have Paul Bloom as a guest, or we have Paul Bloom and a guest and it's a banger? Note: no dogs or baby monkeys were harmed in the making of this episode.
