I read a study that I am now searching for that showed MRI scans of people trying to change their mind about a subject. It consumed huge amounts of energy. People's brains are built to build an accurate, complete view of the survival landscape and forgo any wasted energy beyond that. Tolerence can be socialized in at a young age but changing your mind consumes huge amounts of resources better spent perpetuating survival. People obtain the same life milestones now, only on a protracted timeline. My thesis is that progress will be slower than before, for exactly as long as old/tired humans stick around.
