The HUP plays out everywhere we go with the pleope who we like, who like us, who act and think like us. Maybe it's narcissism, maybe we want to be around ourselves a lot. But I think the biggest takeaway for me isn't really new news so much as it is a call to do better: diversity of anything takes intention and effort. You can't have a diverse worldview in your bubble, so you have to intentionally get outside of it, it won't just happen to you.
