> "I was talking about this experiment" The analogies are meant to demonstrate that sample size is (1) not as straightforward as asking "how many subjects" and (2) less important in circumstances where the signal is strong. In other words, we're trying to give you the tools to evaluate for yourself. The initial article is about "an experiment involving 11 people", and your skepticism seemed to be about whether it's even possible to get valid results with that sample size (answer: yes). Even in this study, yes, you can get a valid result from "only" 11 people.
