Ta. I learned about it from my favourite HN comment (https://news.ycombinator.com/item?id=40856578) and have spent the last 6 months wondering why people don't bring it up more. It may just be a model but it has much explanatory power for why there seem to be so many "stupid" people around. I don't really have the word to describe them; people who are technically reasonable but not convinced by arguments or evidence.
