I'm pretty sure you don't understand PlusCaChange. It's like when you used to try arguing with AmericanIdiot.
Your article is clearly about people who believe vague nonsense, not people who say things that seem vague to you personally. You're trying to construe that having an expanded vocabulary is stupid, and you don't even try to understanding what PlusCaChange is saying in the first place because it's anti-vegan.
Your article seems to sum itself up when it says:
"our findings are consistent with the idea that the tendency to rate vague, meaningless statements as profound is a legitimate psychological phenomenon that is consistently related to at least some variables of theoretical interest."
The people in question are depicted as hippies. Can you see why? I think it's somewhat "hilarious" that you think that article fits your complaint.
I should also mention that your linked site announced that it uses tracking cookies and clogged my browser twice with a long-running script. Thanks.
