Dunning-Kruger theory of mind

Our ignorance of our ignorance of others


On our known-terrible ability to know our terrible inabilities to know about others. Our constant and reliable ability to 1) think we know more about others than we do and 2) never notice it. Manifesting in, e.g. pluralistic ignorance, the out-group homogeneity effect, idiosyncratic rater effect, many other biases I do not yet know names for.

I cannot shake the suspicion that there is some insight in learning process of our minds which explains how our interpersonal understanding capacities are biassed here.

On evaluating others

The feedback fallacy:

The first problem with feedback is that humans are unreliable raters of other humans. Over the past 40 years psychometricians have shown in study after study that people don’t have the objectivity to hold in their heads a stable definition of an abstract quality, such as business acumen or assertiveness, and then accurately evaluate someone else on it. Our evaluations are deeply colored by our own understanding of what we’re rating others on, our own sense of what good looks like for a particular competency, our harshness or leniency as raters, and our own inherent and unconscious biases. This phenomenon is called the idiosyncratic rater effect, and it’s large (more than half of your rating of someone else reflects your characteristics, not hers) and resilient (no training can lessen it). In other words, the research shows that feedback is more distortion than truth.

On understanding how others think

Todo: raid this for references: Why You’re Constantly Misunderstood on Slack (and How to Fix It).

People of higher status are more likely to think that those who disagree with them are stupid or biased — even when their high status is the result of a random process. (Brown-Iannuzzi et al. 2020)

The researchers first analyzed data from 2,374 individuals who participated in the 2016 American National Election Studies Time Series Survey, a nationally representative survey of U.S. citizens. As expected, liberals and conservatives were more likely to describe the opposing political party as uninformed, irrational, and/or biased compared to their own party.

Importantly, the researchers found that this was especially true among those with a higher socio-economic status. Among more liberal participants, higher status individuals displayed more naive realism toward Republicans. Among more conservative participants, higher status individuals displayed more naive realism toward Democrats.

In a follow-up experiment, the researchers experimentally manipulated people’s sense of status through an investment game. The study of 252 participants found that those who were randomly told they had performed “better than 89% of all players to date” were more likely to say that people who disagreed with their investment advice were biased and incompetent.

For ages my favourite go-to-bias to think on here was Fundamental attribution bias, which seems ubiquitous to me.

In social psychology, fundamental attribution error (FAE), also known as correspondence bias or attribution effect, is the tendency for people to under-emphasize situational explanations for an individual's observed behavior while over-emphasizing dispositional and personality-based explanations for their behavior. This effect has been described as "the tendency to believe that what people do reflects who they are".

Apparently it has been called in to question though? (Epstein and Teraspulsky 1986; Malle 2006) TODO: investigate.
