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 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.

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

Some people would rather stay ignorant and self-satisfied.

Some people cheat because they want to, because they can, because it gives them a thrill, or because they just can't do long-term relationships.

Some people are contriving ways and means of making us collapse.
