How do chess masters excel?
Chess masters excel by recognizing patterns in chess positions, allowing them to anticipate moves and develop strategies more effectively. They have better memory for potential chess positions that could arise in real games, enabling them to make informed decisions based on past experiences.

What is the key to developing expertise?
The key to developing expertise lies in deliberate practice, which involves engaging in challenging tasks that push one's abilities to the limit. This type of practice, combined with immediate and clear feedback, allows individuals to improve their skills significantly over time.

Why do political and economic experts struggle with predictions?
Political and economic experts often struggle with predictions because the fields they operate in have low validity environments, making it challenging to accurately forecast outcomes. Despite their expertise, they may perform worse than random chance due to the unpredictable nature of political and economic events. This highlights the importance of recognizing the limitations of expertise and the need for continuous learning and adaptation in these dynamic fields.
