I can see this... but the best way to judge whether such bias exists (and is also a bad thing) is by looking at the success or failure of our startups, right? The free market ain't perfect, but it's better than most other methods of deciding value. This point assumes that we take each other's advice here ;)

Also, I recall a BBC article a while back citing a study showing that ~half of all scientific studies turn out wrong because they failed to exclude variables. The study, below, needs to be supported by other studies in other circumstances (and maybe those exist -- I don't read psy journals).
