How can a mental set interfere with problem-solving?

A mental set can interfere with problem-solving because it refers to a tendency to approach situations in a specific way based on past experiences or habits. When someone is stuck in a mental set, they may only consider solutions that have worked for them in the past, which can hinder their ability to think of new and innovative solutions to problems. This fixation can block their view of alternative methods or approaches that might be more effective in the current situation. Essentially, a mental set limits the problem-solver's ability to adapt their thinking patterns, making it difficult to reframe the problem or look at it from different perspectives, hence preventing the discovery of new solutions. This explanation emphasizes the rigid nature of mental sets and how they can restrict cognitive flexibility, which is crucial for effective problem-solving.
