When people are observed and know they are being observed, they often alter their behavior to conform to expectations. The results found are exactly what any good social scientist in this field would have expected based on decades of prior research.
If you really think you can write a paper with evidence supporting the other side, be my guest. I'm always willing to be convinced by good evidence. Since you can't even correctly understand the paper at hand, however, I'm eager for the hilarity that would result.
Well said, and I applaud your effort to explain this stuff to people who obviously have minimal experience with statistical analysis. The results here are almost identical to the results from the basketball study which, despite the NBA's vicious (and baseless) attacks, was an accurate and well-done study.
Also not that the authors of this study aren't out to say that this is a major problem. In fact, I would say that their results say the opposite, given that one bad call in 100 pitches is probably a very good night behind the plate.
