We'd find problems with many if not most published studies if we scutinized them the same way. People like him get discovered because they step out of their academic bubble into the light of the world stage.

And mind you this is psychology, the entire discipline is only borderline scientific anyway. But even studies in the hard sciences are very often flawed if not outright fabricated. Adjusting data sets to fit the desired result (who'd ever know as long as you do it properly), changing the experiment and measure until they get what they they want, repeated measuring until the "right" data for the paper appeared randomly - those are all things I personally observed in the lab.

Not to even get started on the house of cards that is basing ones flawed assumptions on other flawed studies without even the slightest attempt at replicating their results first. It's standard practice to simply presume what's been published (especially by friendly authors) can be regarded as reliable.
