Im watching Dexter and the guy who plays Mike in Breaking Bad is an fbi official. The Captain in the show, big Nordic head, looks like an SS officer.
So i got to thinking about how tv has a cop "look" and a greaseball criminal look and how HBO so clearly uses CS Coon racial typing.
So that would probably create a feedback loop; kids w that look who consume thousands of hours of media must be affected in how they see themselves.
Anyway who does the type casting? Studio technicians? Are there consulting firms?
Well since you cant study people's behavior apart from their memes "correlation" is worthless and insignificant. It's likelier a testament to the might of the meme and its power over identity and behavior.
