I recently sat down with Australian boxer and podcaster Tiffanee Cook for an episode of her Roll with the Punches podcast. We had a great conversation about a wide range of topics related to my book A Billion Years of Sex Differences. Among other things, we discussed:
How I fell in love with evolutionary psychology and the science of sex differences
The origins of occupational gender gaps
The many causes of the gender pay gap
Why dating apps often make it harder to find love rather than easier
Whether mental-health problems are discrete disorders or arbitrarily defined segments of a spectrum of symptoms
Sex differences in mental-health problems
The possible origins of the trans phenomenon and non-binary identification
The episode is available on Apple Podcasts, on Spotify, and wherever else you get your podcasts. Hope you enjoy it!
If you want to dive deeper into these topics, you can pick up a copy of A Billion Years of Sex Differences here.
