I have an essay in @theargument.bsky.social today, diving into the science on gender differences and making the case that, Mars and Venus style arguments aside, biological essentialism isn't well-supported by the evidence.

I just published my first piece with The Argument, and it's about why parents should let their kids go to the roller rink on their own.

Massive turnout at the #NoKings protest in Pasadena. Calm, peaceful, multigenerational crowd. Patriotic signs and American flags everywhere. I’m still waiting for my check from Soros.

I wrote about whether universities are "too woke" and suffering from "ideological capture." darbysaxbe.substack.com/p/are-univer...
Are universities too woke to exist?
No, we should not defund all universities because of "ideological capture"

Super cool. I'm curious if the salience network changes track with perceived hunger or cravings, or with eating behaviors.
September 15, 2025 at 5:13 PM
So I'm trying to interpret - would you say that salience network connectivity gets more diffuse and perhaps signals better top down regulation of interoceptive signals??
