“Folks, uh, from the cockpit. That noise you heard, we uh, well we appear to have lost an engine. But it’s no problem we’ll be just fine.” Competence. Accept no substitute.

Current models of #radicalization are not equipped to deal with the rapid convergence of multiple, overlapping harms, especially in the context of Com networks. I recently collaborated with Max Taylor and Ethel Quayle on this new piece for Perspectives on Terrorism. pt.icct.nl/article/radi...

Not a single terrorist I've interviewed ever talked about killing people "just for fun."

@chetibby.bsky.social Hey now. Just read your piece on incoherent violent extremism in the Jl of Policing, Intel and CT. Really good stuff. Finishing up a similar paper with my PhD researcher Morgan Shayler, and will incorporate yours. Appreciated your points about MUU not being a 'holding pen.'

Recently had an opportunity to collaborate with the great Clare Allely, with colleagues Courtney Tassin and Sonya McLaren, for an analysis of the Arapahoe High School attack of 2013. Just published in the Journal of Threat Assessment & Management. psycnet.apa.org/doiLanding?d...

Temporary escape from the insanity. Summit of Carstensz Pyramid, west Papua, about 48 hours ago. Highest peak in Oceania and one of the fabled Seven Summits. Very technical climbing and lucky to have had great conditions. L-R Frank McCarthy, Mickey Gutwein, me.

Hello new followers. I’m John Horgan, a professor of psychology who studies terrorist behavior. Don’t believe anyone who says they know what is going to happen next. Nobody does. Believe the Trump administration least of all. The informed voices are out there. Seek them out.

Hello down there!

The University of Texas system has voted to limit 'controversial topics' in class. Where's the academic freedom? "A faculty member is not going to be able do talk about current events without risking being fired. What kind of education is this?" —Brian Evans, President of @texasaaup.bsky.social

So a war is surely around the corner

An unparalleled mountaineer, for sure, but I’ve seen fewer grievances in terrorist manifestos.

RIP Tom Noonan. Truly terrific actor.

Any time I think I can't possibly be more shocked and floored by the outrageous cruelty so proudly on display by this administration, I am quickly proven wrong.

When I got the contract to write a history of concentration camps in 2014, I hoped to keep the US from ending up here. That didn't work out! But now it's critical to understand how much is already in process and the enormity of what's coming. The sooner we act to stop it, the more people we'll save.

Let's ask Billy what he thinks of all this

It’s state terror, not state-sponsored, since these acts are being conducted directly by agents of the state.

These are the last words in the last column I wrote for The Washington Post, titled "When institutions crumble, strongmen step in". www.washingtonpost.com/opinions/202...

I keep saying to people in my life that the problem with writing in these days is that you sound absolutely off your nut for simply saying what is happening.

Hello Seattle. It’s been too long.

Remind me again which homeland security scholars confidently proclaimed the solution to be “more training?”

DHS Hunts Down 67-Year-Old U.S. Citizen Who Criticized Them in Email newrepublic.com/post/206088/...

sometimes i think about that thing a disco elysium dev said in response to someone asking why choosing fascist options lowers your morale. that being a fascist is miserable, since it requires you to believe that you are being dominated by the weak and unworthy in everything you do.

Horrifying and unnerving. DHS sent an administrative subpoena to Google for this retiree's records and even sent armed agents out to his house for the "offense" of writing the following completely anodyne email to a federal prosecutor using an email address he found via Google.
