I just wrote this on FB, where I sometimes feel like a pinata by people have allowed themselves to be loyal mouthpieces for one political party.

I stand by my assertion that anyone who allows their facts or opinions to be shaped by party politics has allowed their intelligence to drop by 50 points. All of us should be making our own decisions issue by issue. If your opinions are fully or almost entirely aligned with one particular political party, I'm talking especially to you. If you refuse to publicly criticize at least some of the actions and corruption of both political parties, your brain has been captured by a mind-virus. There are no good or bad people. There are only good or bad ideas. As detailed in the book by Jonathan Haidt and Greg Lukianoff, The Coddling of the American Mind, "One of the Three Great Untruths is Us Versus Them: Life Is a Battle Between Good People and Evil People." Excerpt from pages 58-59.

The bottom line is that the human mind is prepared for tribalism. Human evolution is not just the story of individuals competing with other individuals within each group; it’salso the story of groups competing with other groups—sometimes violently. We are all descended from people who belonged to groups that were consistently better at winning that competition. Tribalism is our evolutionary endowment for banding together to prepare for intergroup conflict. When the “tribe switch” is activated, we bind ourselves more tightly to the group, we embrace and defend the group’s moral matrix, and we stop thinking for ourselves. A basic principle of moral psychology is that “morality binds and blinds,” which is a useful trick for a group gearing up for a battle between “us”and “them.”In tribal mode, we seem to go blind to arguments and information that challenge our team’s narrative. Merging with the group in this way is deeply pleasurable—as you can see from the pseudotribal antics that accompany college football games.

But being prepared for tribalism doesn’t mean we have to live in tribal ways. The human mind contains many evolved cognitive “tools.”We don’t use all o f them all the time; we draw on our toolbox as needed. Local conditions can turn the tribalism up, down, or off. Any kind o f intergroup conflict (real or perceived) immediately turns tribalism up, making people highly attentive to signs that reveal which team another person is on. Traitors are punished, and fraternizing with the enemy is, too. Conditions of peace and prosperity, in contrast, generally turn down the tribalism.32People don’t need to track group membership as vigilantly; they don’t feel pressured to conform to group expectations as closely. When a community succeeds in turning down everyone’s tribal circuits, there is more room for individuals to construct lives of their own choosing; there is more freedom for a creative mixing of people and ideas."
