If I'm being given information about heart attacks, I'd much rather hear from a doctor who is well informed on the scientific consensus than a survivor of a heart attack, even if the doctor has never had a single heart problem. Why is information about the experiences of gender or race so different than all other information, being that for any other information, experience is neither necessary nor sufficient for expertise? Also, anecdotal experience, even by large numbers of the population, should not be taken as anything significant without a scientific endeavor to interpret them. Consider the numerous parents who will state "As a parent..." when disagreeing with an expert on child development. Even if thousands of parents disagree, even if the expert has never been a parent, an immunologist saying children should receive vaccines is still correct. In all other fields, the expert lacking personal experience has the better perspective than part of the population impacted with their own personal anecdotes.
