Had to share a work van with one of these sort for work. I would get an hour of details on how math is just "a trick to make people believe certain things"

There is literally nothing you can do to sway any of their beliefs, because basic reason and logic are the enemy.
Rather, maybe we need to subvert their base instincts in a way they can turn them towards logic despite their preconceptions and inability to process basic information. Kind of like the mobile game market or unethical media companies which have free reign to influence these people for malicious self gain.
The issue is that ethical people are too upstanding to use such subversive means, which means they will ultimately lose out in our current socio-economic ecosystem
I think smart people need to fight evil with the same tools used by evil, until such tools are invalidated.
