alt Hacker NewsMaybe I misread the comment then.
I read it as a models performance being random and observed differences in the opinions are the results of the overinterpretation of the random outcomes.
I think however that some people seem to be always lucky which indicates that it is not random but rather some fixed differences between people and their environments.
A models adherence to some configuration is a matter of probability. There might be some underlying pattern, but as far as I understand this is not documented and it may be even impossible to do so. So people are just trying stuff and sharing what appear to work. There is no causal link anywhere in this recommendations, and is just based on spurious correlations.
