Thinking set, also known as "inertial thinking", is a special mental preparation state or activity tendency caused by previous activities. Under the constant environment, the fixed situation enables people to solve problems quickly by using the methods they have mastered. When the situation changes, it will prevent people from adopting new methods. Negative mentality is a shackle that binds creative thinking.
