science

I'm in manufacturing/engineering. There's no political definition for who takes the jobs, but I do believe their political leanings very closely align with their office personalities. There's the type that complains when someone takes some _liber_ties in the process, and then there's the type that sits for a minute trying to understand that alternate thought process (although usually met with the initial disapproval). There's the type that writes processes the way they think it should work, then there's the type that will convene with and cooperate with the actual affected workers before and after writing it. But at the same time, despite being rooted in science and hard evidence, compartmentalization is widely available. My household PhD is the most religious person in the office. The person is nice, smart, and competent to the point we filter our profanity around the PhD. Potentially the most creative engineer in the office (or most cocky with expenditure risk) is also one of the most obvious conservatives. Sort of like everyone must follow the social rules except for his design ideas.

The redneck engineers you're talking about are probably people who didn't get the formal education or don't have the corporate bankroll to take their work further

"Nobody wants to work anymore" is a fast track to identifying their news/political commentary sources. As if Janet in accounting dreamt of sending "month end inventory call" emails when she was a girl.

For music, I'd venture that the conservative stars are generally making their version of pop. It's not a rule itself, but a core of conservatism is following a set of existing rules because deviation is ostracized
