As part of my broader project of promoting rationality to a wide audience , I published an article in Salon entitled "Get Donald Trump out of my brain: The neuroscience that explains why he’s running away with the GOP." I'd welcome your thoughts on this article itself, and also meta-comments on the strategy of using mindkillers such as politics to raise the sanity waterline by smuggling in rationality memes into such popular and populist venues.
My understanding of the term is that saying "X believes Y from non-rational causes Z" is properly called Bulverism only when it fulfils two extra conditions:
Without those conditions, there is nothing particularly obnoxious or irrational going on. (Though it could still be wrong, of course.)
(C S Lewis, who coined the term, summarizes Bulverism as "to assume without discussion that he is wrong and then distract his attention from this (the only real issue) by busily explaining how he became so silly" and gives a fictional example of someone saying (to someone else arguing a proposition in geometry) "oh, you only say that because you are a man".)
In this case, the point of the Salon article isn't to convince people to disagree with, or disapprove of, Trump or his supporters (I bet at least 90% of their readers already do). It's to convince them that they should be paying attention to their own non-rational Z-like behaviours. Trump just provides some (alleged) illustrations.
And, in fact, the article doesn't purport (even tangentially) to explain why Trump has supporters (though the subtitle implies otherwise; I am guessing that a Salon subeditor is responsible for that). What it purports to explain via non-rational causes and "neuroscience" is why Trump is getting so much media attention. And unless your view of the media is much more optimistic than mine, we can probably agree that "legitimate arguments and concerns" don't generally have that much to do with how much media attention a person or idea gets.
Salon clearly publishes such an article with the purpose of feelig good about discrediting Trump and his supporters. Readers feel good knowing the author scores a point against Trump and his supporters.
