"A person usually has two reasons for doing something: a good reason and the real reason." — Thomas Carlyle
Our ancestors were clever primitives. Like chimpanzees, they owed their survival to a sophisticated, yet simplistic, dopaminergic system. So sophisticated that scientists are baffled by the intricacies. So simplistic that it reduces all decisions, all choices, all behaviors down to whether they turn dopamine flow on or off.
This basic "stop and go" system continues to work with dumb animals by encouraging healthy behaviors while discouraging unhealthy behaviors. When the system malfunctions, by encouraging unhealthy or discouraging healthy behaviors, it still works by ensuring that the animals don’t survive long enough to reproduce.
The same system, that causes wild animals to remove their DNA from the gene pool, is backfiring with potentially sapient animals whose ancestors figured out how to (temporarily) beat the system. First by indulging in unhealthy behaviors for the sole purpose of triggering gratuitous dopamine. Then by surviving long enough to bequeath flawed DNA and unhealthy habits to offspring.
Junk food, reality TV stars, rabid talk-show hosts, pornography, guns, esteem inflating deceptions, status symbols, money, religion, nicotine, cocaine, caffeine, heroin, and believing that human behavior is inexplicably complex are highly appealing to most humans for the same reason — they all include pleasant expectations of turning on the dopamine = dopamine appeal = yes, yes, yes.
Mosquitoes, worms, snakes, pain, abuse, bullying, and threats to safety, acceptance, status, or finances are repellent because they provoke unpleasant expectations that turn off the dopamine = dopamine repel = no, no, no.
If understanding dopamine appeal/repel had one millionth as much dopamine appeal as Kim Kardashian does this would be common knowledge. The way things stand, understanding how dopamine manipulates behavior has zero dopamine appeal and major dopamine repel.
Does all this mean that the challenge is to come up with ways to add dopamine appeal to information that has maximum dopamine repel?
Does it mean that it's time to accept the possibility that the dopaminergic system is working. Which explains why Homo sapiens are lost in a dopamine-induced ignorance keeping everyone from noticing that we're in the process of purging our species' flawed DNA?
