Why should we listen to the ideas of a rich guy rather than an educator? How many times have have you seen an education expert on this site discussing these topics from a critical standpoint?

The bigger issue is why to people want to listen to rich people rather than experts in the field? This reminds me the climate change where some people don't want to listen to the experts but instead want to listen so someone (or news organization) they already know.

don't discriminate much, take every idea, the odd idea that gots strong reaction (in a good, strange, nonobvious way), probably is on to something.

same idea with anova, the variable that causes a lot of variance is probably significant.
