When someone familiar is part of a group performance, it's almost impossible not to focus on them, oftentimes exclusively. This predisposition can distort your judgment of their actual performance.

Those who have witnessed a close friend or family member's dance performance can easily relate to this phenomenon. Your eyes naturally seek them out in the group, causing you to unintentionally overlook the other performers, thereby impairing your ability to evaluate objectively. I refer to this as the 'Bias of Known.'

This bias is prevalent in various aspects of life. For example: businesses evaluating their products. Small businesses, at times, treat their product as if they were their own offspring, fostering this known bias and hindering their ability to objectively compare their product with others in the market. While protecting something like a child is natural, in the business world, it must face the harsh reality of competition.

I believe that practicing the avoidance of the 'Bias of Known' is essential when aiming to create something that truly stands out and matters in the lives of people.
