This is basically my biggest critique of PG and various other YC leaders. Many of the conclusions, while likely be probably being more "right" than "wrong" in virtue, are derived from intuition and observations, not evidence based. It's even more ironic, given how much emphasis the firm places on evidence based thinking of its portfolio founders versus anecdotally thinking.

Great example:

"One quality that’s a really bad indication is a CEO with a strong foreign accent"[0]

The danger is that I think pg has been "right" about so many things that every time he pontificates about something it's treated as dogma. So when he's "wrong", it'll be ignored. Impressionable people (which likely fits the characteristic of many young tech entrepreneurs) will therefore be lead astray.
