Talking about “Rational” versus “Irrational” behaviour or people … it is not an either/or and “irrational” is a black box
The redundant term “Causal Effect”
-- I’m against the use of the phrase “causal effect” or “causal impact” as this is completely redundant, and a bit holier-than-thou. An “effect” of something is by definition “causal”. Just say “impact” or “effect”.
Saying “External validity” as an either/or (I prefer “generalizability”)
Saying “chickenburger” instead of “Chicken Hamburger”; Chocoholic instead of “chocolate addict” … etc.
