overclaiming

You claim to understand concepts that do not exist.

In a 2003 study, participants consistently claimed knowledge of nonexistent academic terms when asked to rate their familiarity with various topics.

Researchers tested participants on a mix of real and fabricated concepts. Many individuals rated their understanding of the fake terms as high, rather than admitting a lack of knowledge. This suggests a systemic tendency to over-report expertise to maintain a positive self-image.

Your brain prefers the appearance of knowing over the reality of ignorance.
