I’ve heard, in this context, the partial counterargument that he was using traits which are a little fuzzy around the edges (where is the boundary between round and wrinkled?) and that he didn’t have to intentionally fudge his data in order to get results that were too good, just be not completely objective in how he was determining them.
Of course, this sort of thing is why we have double-blind tests in modern times.
