Definition: overconfidence bias (case of overconfidence)
The Overconfidence bias describes the tendency to overestimate one's own judgment, decision-making capacity, or professional competence. People with this bias often rely too much on their gut feeling and experience — even if objective data suggests a different assessment.
Examples of overconfidence bias
Sound familiar?
You're not applying because you don't fulfill 100% of the skills from the job ad? Then you're probably a woman. Studies show that on average, men apply if they only meet 60% of the requirements — women, however, often only when they completely agree. However, it is not only applicants who overestimate or underestimate themselves, but also HR managers.
What is the reason for that?
This is due to hubris
The overconfidence bias refers to the tendency to overestimate one's own judgment.
In personnel selection, this cognitive distortion means that HR managers, for example, are so impressed by their own experience that they believe they can make the right selection decision based on just a few, sometimes irrelevant, criteria. They rely on their instincts — the famous gut feeling.
What else is a bias? We explain:
A bias generally describes a systematic distortion in human perception, thinking, or behavior. It is a type of “mental abbreviation” or bias that subconsciously influences our judgment and decision-making.
These distortions can result from personal experiences, cultural influences, emotional states or evolutionary thought patterns. While they often help us make quick decisions, they can also lead to miscalculations and irrational decisions.
Other examples of biases in the HR process include:
- Confirmation Bias: The Confirmation Bias
We prefer information that supports our existing point of view and ignore conflicting information. - Primacy Effect: The First Impression Mistake
The first impression has a disproportionate influence on the overall assessment and is difficult to change. - Halo & Horns Effect: Distortion due to individual features
A single positive (halo) or negative (horn) aspect outshines a person's entire perception. - Affinity Bias (Mini-Me Effect): The Similarity Flaw
People who are similar to us are automatically rated more positively. - Status quo bias: favoring the existing
Existing conditions are preferred over changes, even if they would be beneficial. - Stereotypes/Gender/Racial Bias
Unconscious prejudices against marginalized groups influence decisions. - Illusory Correlation: The Perception of False Connections
False assumption of relationships between independent properties. - Contrast Bias: The Contrast Effect
Evaluation of a person in direct comparison with previous or successor rather than according to objective criteria. - Conformity Bias: The Adjustment Mistake
Adapting one's own decisions to group opinions due to fear of negative evaluation.
Identifying our own biases is the first step towards becoming more aware and being able to make more objective decisions within personnel selection.
How structured pre-selection helps avoid this distortion is shown by Aivy's assessment procedures.
This effect is one of 17 patterns that shape hiring decisions. The overview is in Unconscious Bias in Recruiting.
