Hiding deceit. If you’re purposefully hiding the truth from someone, you may hesitate to look them in the eye because you’re worried that your eyes will give away the truth, and because creating the kind of intimate bond described above when you’re knowingly duping someone makes you feel especially ashamed. This is why people will sometimes, although not always, avoid your gaze when they’re lying to you, why people say things like: “Look me in the eye when you tell me that!” and why people who do make solid eye contact are considered more trustworthy.
