Social comparison bias
Social comparison bias refers to the tendency to feel dislike or competitiveness toward someone who is perceived as physically, socially, or mentally superior. Closely related is social comparison theory, which suggests that people evaluate their own worth by comparing themselves to others. This theory was introduced in 1954 by psychologist Leon Festinger. Social comparisons considered central to factors such as achievement motivation, perceptions of injustice, depression, jealousy, and even the willingness to stay in relationships or jobs. The core idea is that individuals strive to achieve the best possible outcome relative to their peers. For example, a person may compare the affordable department stores they usually visit with the designer boutiques frequented by their peers. Such comparisons can trigger feelings of resentment, anger, and envy. This bias primarily revolves around wealth and social status. It tends to occur unconsciously, with most people unaware that they are making such judgments. Typically, individuals compare themselves with members of their peer group or with those they perceive as similar.
Research
There are many studies focusing on social comparison and its effects on mental health. One such study examined the relationship between depression and social comparison. Thwaites and Dagnan, in "Moderating variables in the relationship between social comparison and depression", investigated this relationship using an evolutionary framework. They hypothesized that depression could result from the social comparisons people make. This study explored the moderating effects of two factors: the personal importance of the comparison dimensions, and the perceived importance of those dimensions to other people. To measure depression in participants, the researchers used a self-esteem test called the Self Attributes Questionnaire, developed by Pelham and Swann in 1989. The test included 10-point Likert scale ratings across ten individual social comparison dimensions. Additional questions were added to examine beliefs about the importance of these dimensions. Data were collected from a combined clinical and non-clinical sample of 174 individuals. They concluded, based on the data, that social comparison was indeed related to depression. Participants who engaged more frequently in social comparison reported higher levels of depression than those who did so less often. Research has also shown that there are two forms of social comparison. Upward comparison occurs when individuals compare themselves to those who appear better off or superior. In contrast, downward comparison occurs when individuals compare themselves to those who are worse off, often fostering a competitive attitude.Cognitive effects
One major symptom that can occur with social comparison bias is the mental disorder of depression. Depression is typically diagnosed during a clinical evaluation using the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition criteria. Symptoms include depressed mood, hopelessness, and sleep difficulties, including both hypersomnia and insomnia. Clinical depression can be caused by various factors in a person's life. Major depressive disorder is a common mental illness associated with social comparison bias. Depression also has a biological explanation for why people lose hope in life. It is linked to a reduction in the size of the hippocampus and decreased levels of serotonin circulating in the brain. Another negative symptom associated with social comparison bias is suicide ideation. Suicidal ideation is defined as persistent thoughts of suicide and suicide attempts. It can arise from social comparison bias because individuals who compare themselves to those perceived as superior may feel mentally discouraged, believing they cannot achieve or appear in the same way, which leads to low self-esteem. Low self-esteem is one of the main factors contributing to suicidal ideation.Additionally, social comparison bias can increase feelings of anxiety. This anxiety may stem from various concerns, such as one’s progress in life. It can manifest as nervousness about logging on to social media and viewing posts, which may then develop into social anxiety when encountering those same individuals offline. This can act as a potential trigger. Specifically, regarding anxiety and body image, people may be easily triggered while using social media. “A common problem with social media is the tendency for people to compare themselves to others. Social media is a place where people tend to tailor their image to present only positive aspects. When others share stories or images of success, achievement, beauty, love, or happiness, it can trigger feelings of inferiority.”
Physical/Behavioral Effects
Social comparison can lead some individuals to engage in harmful behaviors as a coping mechanism. These may include, but are not limited to, drug/substance abuse, self-harm, eating disorders, alcoholism, and other unhealthy strategies.When it comes to social media, social comparison can also play a significant role. Individuals may take steps such as unfollowing accounts or pages that they find triggering. Conversely, it can be beneficial to follow more positive and inspiring accounts. Taking breaks from social media has also been shown to be helpful.
