*Cognitive bias is a form of thinking that appears to be erroneously based on logical and rational reasoning, leading to incorrect analysis and judgments*.
These shortcuts of the mind are mostly unconscious and systematic. Thus, although we can act on them after the fact, we cannot prevent the brain from producing them. The best way to counteract them is first to be aware that they exist, then to know how our three systems of thought work. Out of the 250 or so cognitive biases known to date the *following three formidable ones deserves special attention in education*
- *Bias blind spot*
The blind spot evokes the visual partiality, we all have an area of our retina which is devoid of photoreceptors, therefore blind, and it is our brain that completes the missing visual portion.
While evaluating our own perceptions, we tend to give *more credit to the information that comes from our thoughts than from our actions*
. In contrast, *we do the opposite when we judge others* , *giving more importance to their actions than to their thoughts*, even if we know the latter.This phenomenon called the “*illusion of introspection*”
In an educational context, the bias blind spot can cause a teacher to behave towards learners in a way that is consistent with specific preconceived ideas that he or she knows to be wrong and would not apply to him or her
