If I was asking about a hitting stance, the proper grip on a two-seam fastball, or how to swing a bat, I'd absolutely ask a baseball "professional". It's what they do for a living and they certainly know more about it than I do. On the other hand, the "laced 'em up" comment came during a somewhat abstract argument on the concept of "clutch hitting". That's not a tangible thing that can be taught or even observed and then declared as truth and most of people siding with "clutch hitting exists" rely completely on anecdotal data to confirm their bias. The same way I wouldn't ask a baker about the molecules and atomic structure of yeast, I wouldn't ask a baseball "professional" about conceptual theory in the sport. It's not "in their wheelhouse", for lack of a better term. I also wouldn't ask a home builder about architectural theory and the physics that go along with complex load-bearing structures. They probably wouldn't have much of a clue about how it works, despite the fact that they build houses every day. The same goes for the mechanic. He can certainly repair an engine but can he design one? These professionals have limited scope in their experience. While they certainly know their trade very well, they should not necessarily be relied upon for the more abstract, peripheral aspects of their career choice. And that's why some of us took umbrage to the "laced 'em up" comment. The conversation itself wasn't even really about baseball; it was about how humans deal with pressure situations and whether it's humanly possible to "step up their game" in a tangible, scientifically observable manner.
