Extreme views are heavily over-represented on social media

Social platforms’ tendency to reward hostile content creates incentives that systematically reward simplistic messages and extreme positions and this fuels populism www.ft.com/content/9251... via @jburnmurdoch.ft.com

I don't know who produced this or what model they used, but this is an unsettlingly good AI summary of my book. It's not perfect, but it's hard to imagine that many human undergrads could do a better job.

Around the World, Many People Are Leaving Their Childhood Religions
In many places surveyed, 20% or more of all adults have left their childhood religious group. Christianity and Buddhism have had especially large losses. Pew Research Center.

Our research on Need for Chaos was focused on how some voters wanted to watch the world burn: www.cambridge.org/core/journal...

With DOGE it now seems to be official government strategy from Trump & Musk

But the goal seems the same: Burning down existing structures for selfish status gain

Every time I see this I wonder why most all the writing I see is on the unique politics and circumstance of young men and not on what's going on for young women. The variation is so much more interesting to explain!
