What is the smart person fallacy and how does it impact decision-making and critical thinking?

The smart person fallacy is the belief that intelligent individuals are always right and make the best decisions. This can lead to overconfidence and a reluctance to consider other perspectives or information. It can impact decision-making by causing people to dismiss valid arguments or evidence that contradicts their own beliefs, leading to poor choices. Critical thinking is also hindered as individuals may not thoroughly analyze information or seek out alternative viewpoints.
