Even the most intelligent people generally behave this way, and it’s tragic. To be effective you must not let your need to be right be more important than your need to find out what’s true. If you are too proud of what you know or of how good you are at something you will learn less, make inferior decisions, and fall short of your potential.

Understand your blind spot barrier. In addition to your ego barrier, you (and everyone else) also have blind spots—areas where your way of thinking prevents you from seeing things accurately. Just as we all have different ranges for hearing pitch and seeing colors, we have different ranges for seeing and understanding things. We each see things in our own way. For example, some people naturally see big pictures and miss small details while others naturally see details and miss big pictures; some people are linear thinkers while others think laterally, and so on.

Naturally, people can’t appreciate what they can’t see. A person who can’t identify patterns and synthesize doesn’t know what it’s like to see patterns and synthesize any more than a color-blind person knows what it’s like to see color. These differences in how our brains work are much less apparent than the differences in how our bodies work. Color-blind people eventually find out that they are color-blind, whereas most people never see or understand the ways in which their ways of thinking make them blind. To make it even harder, we don’t like to see ourselves or others as having blind spots, even though we all have them. When you point out someone’s psychological weakness, it’s generally about as well received as if you pointed out a physical weakness.
