Why radicals can't recognize when they're wrong

It's not just ostriches who stick their head in the sand.

  • Not only does everyone have personal experience with how difficult it can be to change people's minds, but there's also empirical research showing why this is the case.
  • A new study in Current Biology explains why some people seem to be constitutionally incapable of admitting they're wrong.
  • The study shows the underlying mechanism behind being bull-headed, and there may be some ways to get better at recognizing when you're wrong.

If you find yourself in an argument about politics, climate change, religion, or any number of conversation topics that are taboo at the Thanksgiving table, you've probably silent screamed to yourself, "Why won't this jerk change their mind? It seems so obvious!" Not only that, but it seems like the crazier position the other side has, the more obstinate they are that you're wrong, not them.

New research published in Current Biology on December 18, 2018, confirms this feeling: people with radical beliefs actually think differently than those without. Specifically, radicals have less metacognitive sensitivity than moderates.

Metacognition refers to the ability to be aware of and analyze one's own thinking. Metacognitive sensitivity is similar, but more specific: it refers to the ability to distinguish between one's correct and incorrect judgements. The new paper, titled "Metacognitive Failure as a Feature of Holding Radical Beliefs," shows that radicals have measurably less metacognitive sensitivity than moderates.

A radical experiment

First, the researchers developed a model of "radicalism." They distributed a series of validated questionnaires on political orientation, attitudes toward specific political issues, intolerance to opposing views, belief rigidity, and other domains. From these, they developed two factors that explained people's responses: dogmatism and authoritarianism, which, taken together, were considered to define a radical.

In this study, dogmatism referred to one's rigidity of belief and intolerance to opposing viewpoints, while authoritarianism referred to one's adherence to in-group authorities and norms and aggression towards those who did not adhere to those authorities and norms. It's important to note that people from both ends of the political spectrum could qualify as radicals based on these criteria, although people with rightwing politics tended to be more authoritarian, which replicates previous findings on the subject.

Based on this construct of radicalism, the researchers took a new sample, measured their radicalism, and presented them with a straightforward task. Study participants were shown two squares with flashing dots for about 750 milliseconds. Their job was to pick the square that had more dots. But the purpose of this task wasn't to see how perceptive participants were. It was to see how confident they were in their answers, how well they could measure their performance — that is, their metacognitive sensitivity.

After making their choice, participants were asked to rate how confident they were in their answers. In theory, when the number of dots in the two squares were similar (therefore making it harder to select the correct answer), then participants would rate their confidence lower. When their confidence ratings were lower, they would be more likely to have selected the wrong answer. This was true for moderates — high confidence ratings were associated with accuracy, low confidence ratings were associated with inaccuracy. But this was not true for radicals.

One might think that radicals would be consistently overconfident in their answers, but this wasn't necessarily the case. Instead, they simply could not track their performance; their confidence ratings failed to match whether they were correct or incorrect. In short, they were less able to observe and analyze their performance because they were less metacognitively sensitive.

To replicate and further test these results, the researchers tweaked the experiment a bit. Just as before, they presented participants with two squares full of flashing dots, one with more dots and one with less, and asked them to select the one with more dots. This time, though, the researchers showed the same set of flashing dots again after an answer had been selected but before the participants rated their confidence.

Being exposed to the dots a second time was new evidence. If the participants could consider and incorporate this evidence, then they would rate their incorrect and correct answers with even less or more confidence than before, respectively.

Again, moderates performed as expected. But radicals? They couldn't incorporate this new information, at least not when they were wrong. When the new evidence confirmed their answer, radicals rated their confidence in their answer as higher, just like moderates did. When the new evidence showed that they had selected incorrectly, radicals still had higher confidence ratings in their wrong answer than moderates.

Can we become better at metacognition?

"In times of increasing political polarization and entrenchment of opinion, the ability to reflect on our viewpoints may be crucial for a fruitful discourse," said Max Rollwage — the lead researcher on the study — in an interview with Tonic. "It is not yet clear whether reduced metacognition is the cause or consequence (or both) of radicalization, nevertheless it is easy to imagine that deficits in metacognition will contribute to the consolidation of radical beliefs."

Fortunately, metacognition is not fixed. It can be exercised like a muscle. In fact, a significant amount of research in education theory deals with how best to teach metacognition to students, as it can improve learning outcomes. It seems that simply being aware of the concept of metacognition can improve one's metacognitive ability. Meditation, too, has been shown to increase metacognition. If we can improve our ability to reflect on how we think, we might incidentally improve our national and global discussions about politics and policy, become better at recognizing when we're wrong, and — at the very least — improve conversation over the Thanksgiving table.

  • It appears that Earth has a geologic "pulse," with clusters of major events occurring every 27.5 million years.
  • Working with the most accurate dating methods available, the authors of the study constructed a new history of the last 260 million years.
  • Exactly why these cycles occur remains unknown, but there are some interesting theories.

Powerful branding can not only change how you feel about a company, it can actually change how your brain is wired.

  • Powerful branding can not only change how you feel about a company, it can actually change how your brain is wired.
  • "We love to think of ourselves as rational. That's not how it works," says UPenn professor Americus Reed II about our habits (both conscious and subconscious) of paying more for items based primarily on the brand name. Effective marketing causes the consumer to link brands like Apple and Nike with their own identity, and that strong attachment goes deeper than receipts.
  • Using MRI, professor and neuroscientist Michael Platt and his team were able to see this at play. When reacting to good or bad news about the brand, Samsung users didn't have positive or negative brain responses, yet they did have "reverse empathy" for bad news about Apple. Meanwhile, Apple users showed a "brain empathy response for Apple that was exactly what you'd see in the way you would respond to somebody in your family."
