You can't just arbitrarily change (confounding) variables like that for a proper experiment. All other factors (including physique) must remain the same while you change one thing only: occupation.

"confounding" implies occupancy doesn't influce other factors of your life. I'm sure everyone wants the supermodel millionaire genius who's perfectly in touch with the feelings of their parter. If that was the norm then sure, farmers would be in trouble.

My comment was more a critique on online dating culture and the values it weighs compared to in person meetups.

I think it’s possible to create 2 dating profiles with the same pictures and change occupation only. It doesn’t have to be real to measure the impact of occupation.
