Sorry, I guess I'm being slow -- I get that the sample size is too small to confirm the effect, but I'm not seeing where the selection bias is. Is it that the type of people who would be attracted to founding a startup are more likely to apply/be accepted to Olin than Stanford? That seems to confirm the original article's thesis rather than invalidate it, in my eyes, so I don't expect that's what you're thinking..
With enough tiny schools you can find outliers for anything. Give me the stats and I'll show you why a seemingly random school is the epicenter of modern opioid addiction.
The p-value against this result if this school was as good as Stanford by pure chance is 1/10k. There are only 3k 4 year colleges in the USA. The vast majority of which are significantly worse than Stanford.
It is therefore extremely unlikely that pure chance alone would explain this data point.
