Original experiment
The first study investigating the paradoxical effects of thought suppression was conducted by Daniel Wegner in a laboratory in 1987. Wegner was an American social psychologist in the field of mental control, conscious will, etc. His interest of thought suppression was based on Freud's psychopathology theory. Freud posited that it was the unconscious that helped hide unwanted thoughts, but he failed to explain daily cases where individuals deliberately make effort to suppress a thought. Meanwhile, studies have shown that conscious thought suppression is difficult as those thoughts always linger in the mind. To explain these, some researchers started investigation. Wegner was one of them, and he conducted two laboratory experiments in 1987, asking participants to will away the thought of a white bear. In the first study, 34 participants were asked to read instructions inducing them to describe their thoughts verbally. They were randomly allocated to either initial suppression or initial expression condition. The two conditions only differed in the order of tasks. The expression task instructed participants to think of a white bear; the suppression task instructed them not to. In both tasks, participants had to ring a bell every time they thought of a white bear. Results showed that the initial suppression group exhibited more frequent thought of the white bear in the expression task. Initial suppression, hence, produced a rebound effect. The second experiment added a third group, asking participants to think of a red Volkswagen as a distractor during the suppression task. The results confirmed previous findings but showed that a distractor alleviated the paradoxical result caused by initial suppression as the third group rang the bell less frequently. Wegner explains that when individuals try to suppress a thought, they may feel it difficult and then become curious about why the thought is so persistent. Although they may be able to suppress the thought temporarily, later reminders of the thought can produce a preoccupation with the formerly hidden thought. Initial suppression therefore paradoxically increases the frequency of unwanted thoughts eventually.Mechanism
Wegner claims that successful thought suppression requires two distinct mental processes, that must be performed simultaneously. The first process is the operating process, which occupies mental resources to will away the unwanted thought, object, or emotion that is persistent in the mind. It works continuously until the thought is cleared completely. The second one is the monitoring process, which acts as a detector searching for unwanted thoughts. It then replaces them by shifting attention to other objects. When individuals' attention is on another task, their mental resources become limited, making it difficult to conduct the operating process. However, the monitoring process is still running, making individuals aware of those unwanted thoughts. The shutdown of operating processes and the continuance of monitoring reduce their ability to suppress the thoughts, and the unwanted thoughts eventually become even more prominent. This theory explains the effects of increased cognitive load by emphasizing that where there is cognitive effort, the monitoring process may supplant the conscious process, while also suggesting that in order for thought suppression to be effective, a balance between the two processes must exist, with the cognitive demand not being so great as to let the monitoring process interrupt the conscious processes. A 2006 study found that individual differences may be able to account for differences.Evidence
Eating behaviour of restrained eaters
The ironic process theory predicts that suppressing the desire to eat can paradoxically lead to overeating due to limited cognitive resources. Boom et al. conducted an experiment in 2002 to investigate the interaction between suppression, distraction, and the perceived calorie content of the food stimuli. The experiment was a "2 (restrained/unrestrained) * 2 (distraction yes/no) * 2 (perceived calories high/low) design, in which subjects consumed ice cream in a taste test situation." Ice-cream consumption was then measured. Results showed that restrained participants ate more than unrestrained participants, and when there was a distraction, they ate even more. These findings supported the theory. Their attempts to inhibit their desire to eat only produced an ironic result—eating more ice cream.Anger suppression on pain severity and pain behaviours
Burns et al. conducted an experiment in 2008 to investigate the relationship between anger suppression, pain severity, and pain behaviours in chronic low back pain patients. Based on Ironic Process Theory, the researchers supposed that the initial suppression of anger would ironically make the feeling of anger more intense. Participants were randomly assigned to either the suppression or no suppression group. During the experiment, they first completed a task inducing their anger, with a pain behaviour task following. Results showed that the suppression group reported greater anger and pain intensity. They also demonstrated more pain behaviors. "Attempts to suppress anger may aggravate pain related to their clinical condition through ironically increased feelings of anger."Application
The ironic process theory can be applied in the treatment for patients with mood disorders, such as anxiety and depression. The attempts of those patients who try to avoid their negative thoughts and feelings, such as suicidal ideas and frustration, may contradictorily make the thoughts even more persistent in their minds. "Trying not to be sad could over time engender severe sadness." Therefore, therapists should inform patients that negative thoughts may be beneficial and encourage them to accept their feelings rather than suppress them. Studies have also proved that this method could reduce depression.Memorization and mnemonics
Although in certain domains, such asExperience sampling
The experience sampling or daily diary method is one way that psychologists attempt to scientifically measure thoughts. This involves "interrupting people as they go about their daily lives and asking them to record the thoughts they are having right at that moment, in that place", often by using " clickers". One research team atCounteractive strategies
In the course of his years of research, Wegner discovered that interested people invariably asked if there was any way to avoid or suppress the unwanted thought. He and others identified the following strategies: 1. Focus on another object as distractor. 2. Postpone the thought. Set it aside for another time, possibly allowing for a specific duration. 3. Decrease your mental load by cutting back on multitasking. 4. Consciously expose yourself to the thought. Allowing controlled exposure to the thought decreases the likelihood of its unexpected, unwanted reappearance. 5. PracticeCriticism
The generalisability of the theory is still in question. Wegner's study used a white bear, and later studies in this area only used one stimulus as well. It is not known if similar results will be found when other stimuli are used, as the nature of the thought being suppressed, such as whether it is emotional, easily imagined, familiar, or complex, may impact the results.Earlier references

In popular culture
Similar ideas appear throughout popular culture and sayings, often with variations on animal and color, such as "It's as hard as trying not to think of a pink rhinoceros." Ironic process theory is also the basis for the mind game known as " The Game", which constitutes trying not to think about the Game. At the end of the 1984 movie ''See also
