You can easily find stats on this issue on your own if you're interested, I'm tired of doing all the research work for other people and getting nothing in return.

As for which emotional experiences matter, you should evaluate a variety of them, including ones that make you uncomfortable. If you're not in a constant state of mild-self doubt or can't easily articulate opponents' line of reasoning then you're in a bubble.

As parent indicated, this ultimately means surrendering your own motivational choices to whoever has the power to put emotional imagery in front of your monkey brain.

No it doesn't. You are perfectly free to seek out other points of view and emotional experiences that you find unpleasant or distasteful. In the context of politics, one obvious reason to do so is to avoid being put on the defensive by an argument you haven't encountered before. I'm pretty far left but I probably spend more time reading conservative forums and blogs than liberal ones.
