Could people be trained to be less gullible? Or are you as stuck with gullibility as you are with skin colour?

Some people recovering from drugs or alcohol stay with the programs indefinitely, making the recovery program their family, a long-term source of attention rewards.

People can undergo a sudden change of thinking and loyalties under threat of death or intense social pressure and isolation from friends and family.

I do not believe that the colour of one's skin determines whether you are disadvantaged.

People repeat behaviour that leads to flooding their brains with pleasurable chemicals. The short-term reward loop acts over hours to years, and the long-term reproductive success loop over generations.

Fighting hard to protect yourself and your relatives is good for your genes, but when captured and escape is not possible, giving up short of dying and making the best you can of the new situation is also good for your genes.
