Description: Being intelligent and thinking deeply is an amazing skill. In fact, it allows us to solve hard problems, get better grades, finish assignments and projects faster, understand the nuances of a group or context, and know or find out what steps or decisions to take to achieve a goal. However, even though humanity is increasingly embracing rational, scientific thought and tends to believe what it sees and hears, I believe there's a somewhat misguided interpretation of those who arrive at the best conclusions, even if they do so excellently and present almost unassailable arguments. Many people's misunderstanding lies in confusing well-executed work or arguments so solid that they're mistaken for impulsiveness and aggression.
