The Four Horsemen of the Evolutionary Apocalypse
My latest appearance on the Modern Wisdom podcast, plus a new review and a new interview about A Billion Years of Sex Differences
Latest Podcast Appearance
This was a fun one: the Modern Wisdom evolutionary psychology roundtable featuring Chris Williamson, Macken Murphy, Rob Henderson, and yours truly. We covered everything from looksmaxxing and the ick to the dangers of ignoring sex differences, with lots of laughs, disagreements, and rabbit holes along the way.
You can find the episode on Apple Podcasts, on Spotify, or wherever else you get your podcasts. You can also watch it on Chris’s YouTube channel.
If you enjoy the conversation and would like to explore these topics in greater depth, you can pick up a copy of my new book A Billion Years of Sex Differences here.
A New Review of A Billion Years of Sex Differences
A Billion Years of Sex Differences was recently reviewed in the Swedish newspaper The Bulletin. The review, by Jakob Sjölander, covers a lot of ground, but I particularly like the last few paragraphs, which nicely capture one of the central messages of the book.
In the wealthy, free world, we now have the means, time, and opportunity to be irritated by the opposite sex’s quirks as never before. Men have the freedom to fritter away time on video games, and women on Instagram—so that is what we do.
This obscures the fundamental truth about men and women: that we are on the same side; that we need and love one another; that our similarities far outweigh our differences; and that no man remains unscathed when his mother, sister, or daughter is harmed, just as no woman remains unscathed when her father, brother, or son is harmed.
Our goal should be to create a society for everyone—men and women alike—rather than trying to reshape people to fit society. Steve Stewart-Williams’s book is part of that project.
A New Interview About A Billion Years of Sex Differences
The Swedish magazine Kvartal just published a 5,000-word feature article about A Billion Years of Sex Differences. Written by Jonathan Norström, the piece was based on an interview we did a few weeks ago. I don’t speak a word of Swedish myself, so I can’t vouch for anything I said. But the artwork is cool!
Thanks for reading, and thanks to everyone who’s supported A Billion Years of Sex Differences since it came out. More podcast appearances, reviews, and interviews to come!
