If a person stubbornly believes that they know everything, they are often in a state of cognitive blind spot.

Especially when the facts have clearly disproved their viewpoint, they still refuse to acknowledge it, cannot reflect on themselves, and even insist stubbornly due to concern for their image;

The risks hidden in such cognitive inertia can be considered latent dangers, and the decision-making errors or behavioral deviations resulting from this may lead to immeasurable losses.

Only by breaking the illusion of "self-imposed limitations" and accepting facts and feedback with an open mind can one achieve a leap in cognitive levels.
