Sure, but unless someone's taken the time to do the studies, anecdotes are the best data we have. And I'm not entirely dismissive of personal feelings either, when they're formed as the result of years of experience exploring different techniques. Especially because I tend to feel there's more to software development than just "engineering", and there's a creative side to it that's never going to be completely reducible to whether technique A is measurably better than technique B. Certainly in a tech lead type role, being aware of how those in your team enjoy working individually while still sticking to basic principles and guidelines that allow the team as a whole to produce quality code in a timely fashion is one of hardest balancing acts to get right.
