Because I didn't just state a blanket opinion. I dug into the studies, looked for data to test one of them in depth, and found it to be highly flawed. I called into question the methodology employed by the studies, as well as overgeneralizing and overreaching conclusions they're drummed up to support. The evidence that at least some studies are flawed and the methodology is shoddy should make you question the universal claim "... actually they perform no better than SPRs on average". That's why you should be interested.

My personal experience with interviewing is certainly not as important piece of evidence against the article as the specific criticisms of the studies. It's just another anecdotal data point. That's why I didn't expand on it as much as I did on the wine study, although I do believe it can be made more convincing through further elucidation.
