What is a common characteristic of individuals who rely heavily on their mental sets?

Individuals who rely heavily on their mental sets tend to approach problems using established strategies that they have previously found effective. This characteristic can lead to a fixation on these familiar approaches, making it difficult for them to adapt or alter their strategies even when faced with new challenges.

As a result, they might struggle to recognize when a familiar approach is ineffective. This rigidity can impede their ability to explore alternative solutions that might be more appropriate for the specific situation. Mental sets are often built on past experiences and successes, so when those methods fail, those reliant on them may not readily notice the need for change or innovation in their problem-solving processes.

In contrast, the other options reflect traits or behaviors that are not typical of individuals with strong mental sets. Those who solve problems unconventionally exhibit creativity and flexibility, while cognitive flexibility itself points to an ability to adapt one's thinking. Similarly, a preference for collaboration suggests a more open-minded approach that contrasts with the rigidity suggested by excessive reliance on mental sets.
