Anecdotes? Sure. My wife loves to trade options. I generally avoid them, except for buy-writes. Across investments, she enjoys taking higher risk positions than I.
I can't say that gender doesn't play a role, and it would make sense if gender were a factor, but I don't see how it could be anything close to a dominant factor.
By "anecdote", I meant "a culture or subgroup where women are reputed to be more risk taking than men", not "an individual example". No one disputes that individual examples can probably be found in any culture, and their existence doesn't contradict my claim.
...I don't see how it could be anything close to a dominant factor.
Suppose it were a dominant factor. How would the world be drastically different than it is today?
