Milquetoast, vice versa, vice-sa versa (sic), erudite, illucidate, confusing size for importance (saying big meeting instead of important meeting), commensurate, je no se qua, anything in Latin, anything in another language, latent space, probability space. We use lots of techniques to try to punch-up our perceived intelligence, neurotypical people do it sometimes because they have a tendancy to associate station in a hierarchy with “good traits” like intelligence and use these smart sounding words to try to project authority… ? Maybe? Sometimes I use smart sounding words to talk over/around people when I don’t want to engage them for whatever reason. People after weird. I think it’s easy to see when people are dumber than you, and much harder to see when people are smarter that you; especially the degree to which (to which, being another smart sounding word particle. Particle when used to ike this, another smartness showing phrase.) they are smarter than you. My rule of thumb is that if someone’s dumb, that’s easy for you to tell, but if you can’t tell that they are blatantly dumb, they are likely to be at least close to you in intelligence. If they seem smart, they are likely smarter than your best case scenario guess (they are likely smarter than you think). Everything goes out the window when you start talking about people who learned English as not their first language. Also acronyms.
