What is a thought tunnel?

Thought tunnels, the tendency for people to focus heavily on their thoughts without considering other inputs such as the input of others ,are one way thinking patterns that can block a clear view of reality..

Thought tunnels happen when, as you work toward your goals, you fall victim to your brain’s need for efficiency. Because there’s much going on in most environments—whether they are external or internal—your brain starts filtering out what it might deem as unnecessary information; it simply can’t take it all in.
