Insight is achieved on an individual basis, while trial$-$and$-$error learning occurs through team efforts.

Insight is only applicable to humans, whereas animals employ trial and error.

Insight occurs in a moment of internal breakthrough, while trial$-$anderror learning occurs through repetition.
