You have to be careful what you're measuring. How well someone works in on a job is different from the first face-to-face meeting/interview. A better predictor of how well someone communicates and interacts in a team is probably (1) how well they communicate in the application process and (2) how well their previous employers said they communicate. A blind interview could still have text correspondence, programming interview questions, etc. I still think you're not learning what you think you're learning from face-to-face. I don't have data on that, but then again, I'm guessing you don't either.
