What does 'tunnel vision' refer to in the context of problem solving?

In the context of problem solving, 'tunnel vision' refers to ignoring alternative perspectives. This phenomenon occurs when an individual becomes so focused on a specific solution or detail that they fail to consider other options or viewpoints that may be crucial to finding a comprehensive solution. By concentrating excessively on one aspect of a problem, a person may overlook key information or innovative ideas that could lead to more effective outcomes. This narrow focus can hinder creativity and limit problem-solving efficacy, which is why recognizing the potential for tunnel vision in decision-making processes is important.
