I would also expect that an extremely common name, like John Adams, might have negative consequences that wouldn’t be picked up by a study, if the study doesn’t distinguish somewhat common names and names that are common enough to sound like cliches.

A golden-mean effect where names which are too rare hurt and names which are too common also hurt is one of the first and most obvious hypotheses which come to mind, and I would be extremely surprised if no researcher had checked for this and this suggestion either debunked or embraced with qualifications.
