Our brain works with mental shortcuts. They are useful for making fast decisions, but they constantly distort reality. We confirm what we already believe, ignore what makes us uncomfortable, and give more weight to recent or emotional information. This is not an individual failure or a moral flaw, it is how the human brain is designed. No one is exempt from this, regardless of intelligence or experience.

The real difference is not in having no biases, but in knowing they exist and acting accordingly. Some people actively monitor them and build systems to reduce their impact. They seek opposing views, expose themselves to data that does not reinforce their position, and distrust their first conclusions. It is not about being right, but about getting a little closer to reality in a world that constantly pushes in the opposite direction.
