I've thunk and thunk and can't come up with a reason why it's second nature for me to go from double triggers to a single one, without any problems, and vice versa. I can also shoot the rear trigger first, then go to the front without any conscious thought. I began with double triggers at age 8, went to a single at 12, and didn't shoot double triggers for some 30 years or so.
Maybe the less intelligent one is, the easier it is to swap around without without any thought. I would certainly qualify in that regard.
Situational awareness. It is slowly destroyed in Ruffed Grouse hunters as they age.
Best,
