Reaction formation is a defense mechanism in which people express the opposite of their true feelings, sometimes to an exaggerated extent. For instance, a man who feels insecure about his masculinity might act overly aggressive. Or a woman with substance use disorder may extol the virtues of abstinence. This dynamic is often summarized by Shakespeare’s famous line in Hamlet: “The lady doth protest too much, methinks.”

The concept of defense mechanisms was developed by Sigmund Freud and his daughter Anna Freud. They conceptualized a spectrum from mature to immature defense mechanisms, on which reaction formation is considered intermediate. Many Freudian theories have been disproven over time, but defense mechanisms like reaction formation have endured.

Reaction Formation in Therapy and Mental Health

The counterintuitive tendency to adopt beliefs diametrically opposed to one’s own is driven by a desire to protect the ego—one’s true nature may be deemed unacceptable by the individual, his or her loved ones, or society at large.

For example, a man who desperately craves love but can never seem to develop a relationship may begin to outwardly espouse misogynistic views. By denying his true feelings, he can protect his self-esteem.

Reaction formation may be a temporary coping mechanism, but it’s unproductive in the long run. It ignores underlying beliefs or challenges that need to be addressed, which can hurt mental health.

When does reaction formation become problematic?

Reaction formation occurs because an individual is anxious or uncomfortable about a particular belief, trait, or preference. By demonstrating the opposite, that uncomfortable characteristic remains unacknowledged, both to themselves and others. But it’s healthier for people to express their authentic selves, so reaction formation can hurt well-being over time.

How is reaction formation addressed in therapy?

If a patient seems to have intense, bold, or exaggerated beliefs about something, this may signal that reaction formation is at play. A therapist might address that by helping the patient to explore and accept the underlying challenge that is causing distress. If a young man insists that he has a perfect relationship with his father, the therapist may help the patient work through a conflict with his father that he is anxious to acknowledge.

Reaction Formation in Everyday Life

Reaction formation can be confusing to identify, because the person is often very insistent about their beliefs. And it’s important to state that most people who are passionate about their beliefs are genuine—trusting the person should be the first response. But there are still instances in which reaction formation occurs in daily life, such as in relationships or politics.

Can reaction formation affect relationships?

One way reaction formation occurs in relationships is when one person is uncomfortable with their feelings of affection for the other. Instead of embracing the person, reaction formation may lead them to disengage, argue, or hurt the person. This is an adult version of a common childhood dynamic, when teasing, hair-pulling, and other calls for attention may signal that one child has a crush on another.

Can reaction formation involve sexual beliefs and opinions?

The tendency to publicly and vehemently protest an uncomfortable desire sometimes manifests in those who struggle with sex or sexuality. For example, there have been examples of politicians who preach against homosexuality yet are gay themselves, and politicians who advocate for legislation against child molestation yet have sexually abused children themselves. Research shows that conflicting moral and religious beliefs about porn may contribute to self-identification as a porn addict. Although there are many contributing factors in these situations, one might be that discomfort with aspects of sex and sexuality leads to reaction formation.
