Quizplus · Accepted Answer

John has encountered this problem before and knows what steps to take to solve it. He is approaching the problem with a preconceived notion of what has worked in the past, which is an example of a mental set. Insights involve sudden realizations or aha moments, confirmation bias is a tendency to seek out information that confirms preexisting beliefs, and heuristics are mental shortcuts for problem-solving.
