Which of the following is NOT a roadblock to problem solving?

The answer highlights that excessive collaboration is not considered a roadblock to problem solving. In fact, collaboration typically enhances the problem-solving process. It brings together diverse perspectives and expertise, fostering creativity and innovation. This collaborative approach can lead to more effective solutions because it encourages open communication and the sharing of ideas.

In contrast, over certainty, fear of the unknown, and tunnel vision can restrict problem-solving effectiveness. Over certainty may lead to an unwillingness to consider alternative viewpoints or to acknowledge the complexity of a problem. Fear of the unknown can paralyze decision-making, as individuals may avoid engaging with issues that are unfamiliar or unpredictable. Tunnel vision restricts focus to a narrow set of solutions or perspectives, limiting the ability to see the broader context or additional possibilities. Collectively, these factors impede critical thinking and adaptability, which are essential for effective problem-solving.
