Oddbean new post about login | logout @91f09b7b Oh, I haven't seen that. Sounds like it's right up my street. Which Croft are they, please?
@2184a19c That would be William Croft (2000). Explaining Language Change: An Evolutionary Approach. I could have sworn there was a whole big discussion of it, but it seems to be buried in section 7.4 (pages 174-194) on propagation. Seemed like a huge deal to me when I read it! (full disclosure: Bill Croft was on my dissertation committee, and my feelings about him are ... complicated) https://books.google.com/books?id=5_Ka7zLl9HQC
