Just as we work to escape or avoid any aversive or unpleasant event, most of us also work to escape or avoid our painful or aversive thoughts, feelings, emotions, and other private experiences. But many of the strategies we use to avoid painful private thoughts or experiences can actually be quite harmful and just make things worse.
For example, research shows that trying to suppress a thought typically makes the thought occur more frequently, not less1. Many psychologists believe this constant and active attempt to avoid unpleasant thoughts and private experiences is at the root of many psychological disorders.
