What defense mechanism involves adopting an opposite idea to suppress a feared impulse?

The concept of adopting an opposite idea to suppress a feared impulse is representative of reaction formation. This defense mechanism allows individuals to cope with anxiety or internal conflict by behaving in a way that is directly contrary to what they truly feel or desire. For example, someone who harbors negative feelings toward a person might express overly positive sentiments or behave in an excessively friendly manner towards that individual, effectively masking their true feelings. By expressing the opposite emotion or impulse, the individual helps to shield themselves from the anxiety that may accompany their original feelings, thus creating a form of psychological defense.

In contrast to reaction formation, other defense mechanisms like projection involves attributing one’s own unwanted feelings or impulses to someone else. Denial refers to refusing to accept reality or facts, thus avoiding uncomfortable emotions or thoughts. Rationalization involves justifying actions or feelings with logical reasons, often overlooking the true motivations. Each of these mechanisms serves different functions, but none embody the specific characteristic of expressing an opposite view to manage internal fears, as reaction formation does.
