Many anglers consider trout exceptionally "smart" fish that can be difficult to catch due to their wits. The truth is that they are no more intelligent than catfish, bass or any other species. The real difference between trout and other game fish is the way in which they use their senses. And their remarkable ability to react to, and learn from, the stimuli they see, hear, feel and smell. With their actions based on instinct, not brainpower.
