No. That may contribute to the lower figure in males, but the prevalence
rates are calculated from population studies, rather than guesses about what
might be happening in the people you haven't seen.

Suicide, incidentally, is commoner in males.

Where did you actually get your figure from? I have never seen any figures
for "actual reported incidences of depression" that would yield such a huge
discrepancy in lifetime risk for men and women.

True: all the points about creativity are unaffected by the stats.
