I was surprised the blog post did not mention Modes of Persuasion , which were codified in 4th century BCE by Aristotle. Ethos: appeal to authority Pathos: appeal to emotion Logos: appeal to logic I found the post's added description of more recent psychological studies interesting though. https://en.m.wikipedia.org/wiki/Modes_of_persuasion
A lot has happened since 4kBC. Not sure if you noticed.
