Heavy reading but interesting. Would even be better if the authors didn't all feel the need to repeat that they know that the Goldwater rule prevents them from analysing a public figure and therefore they are absolutely not doing that, before proceeding with their analysis of dt. The most interesting authors are the non-psy because they do not repeat what the others have already said :-) worth a read. This one is from 2017. There is another one from 2025 which I'll review later.
