Why is it so difficult to look people in the eyes?
If you have difficulty looking people in the eyes, you are not alone. I was just at the grocery store and found myself looking everywhere except at the cashier.
There is often an intensity when looking someone in the eyes that makes us feel simultaneously invasive and vulnerable. This is why holding one’s gaze helps with bonding by heightening one’s connection to the other person. I believe this is worse when you are an introvert. We do have a tendency to sense people and see a lot more than just a person’s words.
Some scientists from Kyoto University have discovered that maintaining eye contact while processing what a person is saying is sometimes taxing on the brain. I would wager to say that this is especially true of introverts who are much more internalized than externalized.
