Added (11th Sept): Nonlinear have commented that they intend to write a response, have written a short follow-up, and claim that they dispute 85 claims in this post. I'll link here to that if-and-when it's published.

Added (11th Sept): One of the former employees, Chloe, has written a lengthy comment personally detailing some of her experiences working at Nonlinear and the aftermath.

Added (12th Sept): I've made 3 relatively minor edits to the post. I'm keeping a list of all edits at the bottom of the post, so if you've read the post already, you can just go to the end to see the edits.

Added (15th Sept): I've written a follow-up post saying that I've finished working on this investigation and do not intend to work more on it in the future. The follow-up also has a bunch of reflections on what led up to this post.

Epistemic status: Once I started actively looking into things, much of my information in the post below came about by a search for negative information about the Nonlinear cofounders, not from a search to give a balanced picture of its overall costs and benefits. I think standard update rules suggest not that you ignore the information, but you think about how bad you expect the information would be if I selected for the worst, credible info I could share, and then update based on how much worse (or better) it is than you expect I could produce. (See section 5 of this post about Mistakes with Conservation of Expected Evidence for more on this.) This seems like a worthwhile exercise for at least non-zero people to do in the comments before reading on. (You can condition on me finding enough to be worth sharing, but also note that I think I have a relatively low bar for publicly sharing critical info about folks in the EA/x-risk/rationalist/etc ecosystem.)

tl;dr: If you want my important updates quickly summarized in four claims-plus-probabilities, jump to the section near the bottom titled "Summary of My Epistemic State".
