Reality Distortions: Overestimation Bias

The statistical tendency toward unfounded optimism.

In studying how people make decisions, we discover the existence of various cognitive biases that shape our mental architecture.

We can define a bias as a pre-established inclination or instinctive preference that distorts our judgment.

For example, if we had a bad experience in childhood when tasting a certain food, we develop an aversion that leads us to systematically reject it in adulthood, wrongly assuming that our taste has not evolved.

Unfortunately, we possess a vast number of these mental shortcuts, and the vast majority of them lead us to make serious analytical errors.

One of the most preva lent and striking biases is that of optimism and personal overvaluation.

Systematically, human beings tend to be excessively positive about their own abilities, judging their performance far above the objective reality in virtually any discipline or daily task.

False perception of competence versus the average

The false perception of superiority is demonstrated in multiple statistical studies.

If we consult a large group of individuals about their level of skill in the kitchen, we will find that more than ninety percent classify themselves as above-average cooks.

Mathematically, it is impossible for such a number of people to be above average, since the average divides the population into exactly two halves.

This illusion persists in many areas: the vast majority of university students anticipate outstanding grades, far above the actual performance of the group.

Curiously, when we are completely lacking in knowledge about a subject, we are able to admit our ignorance.

However, as soon as we acquire some basic notions and manage to execute a task in a moderately acceptable manner, our ego intervenes and convinces us that we have reached the level of an exceptional expert, greatly overestimating our true technical and operational capacity.

Summary

Individuals exhibit a natural predisposition toward exaggerated optimism. This cognitive distortion leads us to overestimate our own capabilities in various life areas.

Most people consider themselves statistically above average. This illusion of competence generates false expectations and complicates the acceptance of one's own mistakes.

Recognizing this overvaluation bias is fundamental in the service offered. Representatives must treat users by validating their perspective without confronting inflated egos.
