Here are four incredibly bad ideas (that are still commonly believed):

1) That people should be judged for, blamed for, or feel shame about the behavior of their ancestors.

Of course, if your ancestors did bad things, you should condemn those acts. And if you directly benefit from something bad your family member did, you should consider if you can make amends.

But, logically, people cannot be morally responsible for events that they were unable to affect.

This bad idea (that we are responsible for the behavior of our ancestors) is partly responsible for numerous cycles of violent conflict, as well as for unjust punishments and unhelpful guilt.

2) That small differences in group means are a good justification for jumping to conclusions about members.

This idea is partly responsible for a variety of forms of prejudice and harmful stereotyping.

Epistemically, a small mean difference provides only a sliver of evidence about individuals. Morally, it’s unjust to treat individuals as though only their group matters.

3) That there’s a simple explanation for all or most human behavior.

Variations on this idea have led to a great deal of confusion about human nature.

Human behavior is not all about sex, or self-interest, or happiness, or status, or individual survival, or even love.

Humans have a very diverse set of forces that influence behavior: emotions, culture, values, habits, instincts, heuristics, goals, etc.

4) That you need to follow a prescribed template in order to have a fulfilling life.

This idea has led to countless people being pressured into or trapped in lives that are bad for them.

Some people will be happiest as homemakers, others as professionals, and still others as adventurers, etc. Sometimes, the best life for a person will match the stereotype for their gender or group; other times, it will be the opposite, and at other times, it will seem completely out of left field.

Our boxes are much too small to force people’s lives into.

1: Start to think that one ideology you like – which contains genuine benefits, truths, and positive moral elements – might be the only valid perspective.

2: Surround yourself with believers until you’re convinced that your view is common and normal.

3: Ignore your own doubts so that you can fit in better. Join in on chastising (and eventually ostracizing) insiders who doubt too much. Punish slightly more harshly than you feel is fair in order to prove that you are one of the good guys.

4: Since challenging the ideology is punished, pretend to believe more than you really do – contributing to the sense that almost everyone else has no doubts – in a self-reinforcing cycle.

5: Assume that since your view is obviously correct, normal, and morally good, those who strongly oppose your view are bad people.

6: Since you are good and they are bad, conclude that you, as the good guys, should try to destroy them (figuratively, or in extreme cases, literally).

7: But how can you tell who is bad? Decide that a set of beliefs that sound similar to the bad people’s beliefs are off-limits. Anyone who believes them is probably bad. In those cases, humane treatment is no longer necessary.

8: Even just spending too much time with one of the bad people, or speaking well of them, is morally suspect. Why would you do that if you weren’t bad too?

9: Unfortunately, some true beliefs were accidentally put on the “bad” side of the good/bad dividing line. Now there are true things that you would become a bad person for believing.

10: Because of that, you and your group must avoid looking at reality too closely, lest you become bad too.

11: If you start to notice something true that you’re not allowed to believe, look away quickly or contort reality to make it seem different than it is.

12: Intensify your self-delusion and your punishment of non-believers so that you can make sure that still more people in your group will delude themselves out of fear.

13: Start teaching children (before they are old enough to think for themselves) that your belief system is the only correct one, perpetuating the system for future generations.

14: Congratulations! You’ve succeeded at being a good person who harms the world. Your mostly good ideology has eaten itself and has become more bad than good.

This has happened many times throughout history, and it will happen many more times. Watch out for this pattern so that you (and the people you love) don’t end up as “true believers” who do harm by accident.
