Anderson and Bushman never met something that didn't cause "aggression." And in the several studies coauthored by Anderson that I have read I have not seen a definition of what they mean by aggression. I remember one mentioning "raising your voice."
Then the news media just reads the abstract and says "a new study shows videogames make you violent!"
Oh yeah, the "Hot Sauce Paradigm" easily quantifiable, never backed up that it actually correlates to aggression in real life. From Adachi and Willoughby (2011):
"Lieberman et al. [1999] found that scores on [the hot sauce] paradigm were positively related to both trait and physical aggression scores on the Buss and Perry (1992) Aggression Questionnaire, supporting the convergent validity of the Hot Sauce Paradigm, although to date no study has measured its association with aggressive behavior outside the lab."
My favorite was where they used the volume of hot sauce poured into a cup as the measure of aggression.
Hopefully they've come up with some better ways of measuring it since then.
