Lying in plain sight [closed]

Solution 1:

reaction formation

...is a type of defense mechanism in which a person acts in the exact opposite manner to his own disturbing or socially unacceptable thoughts or emotions. This behavior is often unconscious and appears exaggerated, perhaps in an effort to overcompensate for the embarrassment, guilt or repulsion the person feels regarding his private thoughts.

Some colorful examples...

Let's say that you secretly harbor lustful feelings toward someone you should probably stay away from. You don't want to admit to these feelings, so you instead express the very opposite of those feelings. This object of your lust now becomes the object of your bitter hatred. This defense mechanism could be subtitled the "lady doth protest too much," that wonderful quote from Hamlet. A less highbrow example is "Church Lady," the old Dana Carvey character from Saturday Night Live. Her secret obsession with pornography became reversed into her extreme scorn for all things sexual. In short, reaction formation means expressing the opposite of your inner feelings in your outward behavior.
