Crab mentality, also known as crab theory, [1] [2] crabs in a bucket [a] mentality, or the crab-bucket effect, is a mentality of which people will try to prevent others from gaining a favourable position in something, even if it has no effect on those trying to stop them. It is usually summarized with the phrase "If I can't have it, neither can you". [3]
The metaphor is derived from anecdotal claims about the behavior of crabs contained in an open bucket: if a crab starts to climb out, [4] it will be pulled back in by the others, ensuring the group's collective demise. [5] [6] [7]
The analogous theory in human behavior is that members of a group will attempt to reduce the self-confidence of any member who achieves success beyond others, out of envy, jealousy, resentment, spite, conspiracy, or competitive feelings, in order to halt their progress. [8] [9] [10] [11]
Tesser's self-evaluation maintenance theory (SEM) [12] suggests that individuals engage in self-evaluation not only through introspection but also through comparison to others, especially those within their close social circles. When someone close to an individual excels in areas they value, they may feel threatened and act in ways that downplay their achievements. [13] This mechanism can partly explain why individuals may attempt to pull down those who achieve more than themselves as a way to protect their own self-esteem and social standing. Emotions such as envy may be generated when individuals feel threatened during self-evaluation. [14] This can lead to a desire to diminish the well-being of others, particularly when their success highlights the individual's own failures or inadequacies. [15]
Relative deprivation theory proposes that feelings of dissatisfaction and injustice arise when people compare their situation unfavorably with others' situations. [16] This sense of inequality, rooted in subjective perceptions rather than objective measures, can deeply influence social behavior, [17] including the phenomenon of crab mentality. When individuals see their peers achieving success or receiving the recognition they feel is undeserved or unattainable for themselves, it can trigger actions aimed at undermining these peers' accomplishments. [18] The concept emerged from a study of American soldiers by Stouffer. Soldiers in units with more promotions were paradoxically less satisfied, feeling left out if not promoted themselves, despite better odds of advancement. [19] This reflects how relative deprivation fuels dissatisfaction by comparing one's situation to others. By "dragging" others down to a similar level, individuals might feel a sense of satisfaction. Thus, crab mentality can be viewed as a response to perceived social inequality, where pulling others down becomes a strategy to cope with feelings of inadequacy or injustice.
Zero-sum bias, where individuals perceive that they can only gain at the expense of others, may contribute to crab mentality. [20] This bias is rooted in a fundamental misunderstanding of success and resource distribution, leading to the incorrect belief that success and resources are limited and one person's gain is necessarily another's loss. [20] Such a worldview fosters competitive rather than collaborative social interactions, encouraging behaviors that aim at hindering others' achievements to protect one's perceived share of limited resources, [21] like crabs in a bucket. In Daniel V. Meegan's study, researchers found that students expected lower grades for peers after seeing many high grades already awarded, despite being in a system where high grades are unlimited. [20] This illustrates how people often view success as a limited resource. Thus, when they see their peers successfully "climbing out of the bucket", they may try to hinder their progress to ensure their own chances of success remain unchanged.
It's crucial to differentiate crab mentality from strategic competition, where actions are calculated for self-interest and personal gain. [22] People's rational behaviors are aimed directly at benefiting themselves. [22] Since it is driven by cognitive biases and emotions, [23] crab mentality is often a reactive, non-rational behavior that seeks to level the playing field by pulling others down, even though there are no direct benefits to the individual.
Social psychology is the scientific study of how thoughts, feelings, and behaviors are influenced by the actual, imagined, or implied presence of others. Social psychologists typically explain human behavior as a result of the relationship between mental states and social situations, studying the social conditions under which thoughts, feelings, and behaviors occur, and how these variables influence social interactions.
Self-esteem is confidence in one's own worth, abilities, or morals. Self-esteem encompasses beliefs about oneself as well as emotional states, such as triumph, despair, pride, and shame. Smith and Mackie define it by saying "The self-concept is what we think about the self; self-esteem, is the positive or negative evaluations of the self, as in how we feel about it ."
The bandwagon effect is a psychological phenomenon where people adopt certain behaviors, styles, or attitudes simply because others are doing so. More specifically, it is a cognitive bias by which public opinion or behaviours can alter due to particular actions and beliefs rallying amongst the public. It is a psychological phenomenon whereby the rate of uptake of beliefs, ideas, fads and trends increases with respect to the proportion of others who have already done so. As more people come to believe in something, others also "hop on the bandwagon" regardless of the underlying evidence.
Psychology is an academic and applied discipline involving the scientific study of human mental functions and behavior. Occasionally, in addition or opposition to employing the scientific method, it also relies on symbolic interpretation and critical analysis, although these traditions have tended to be less pronounced than in other social sciences, such as sociology. Psychologists study phenomena such as perception, cognition, emotion, personality, behavior, and interpersonal relationships. Some, especially depth psychologists, also study the unconscious mind.
An attitude "is a summary evaluation of an object of thought. An attitude object can be anything a person discriminates or holds in mind". Attitudes include beliefs (cognition), emotional responses (affect) and behavioral tendencies. In the classical definition an attitude is persistent, while in more contemporary conceptualizations, attitudes may vary depending upon situations, context, or moods.
In psychology, an attribution bias or attributional errors is a cognitive bias that refers to the systematic errors made when people evaluate or try to find reasons for their own and others' behaviors. It refers to the systematic patterns of deviation from norm or rationality in judgment, often leading to perceptual distortions, inaccurate assessments, or illogical interpretations of events and behaviors.
In psychology, the false consensus effect, also known as consensus bias, is a pervasive cognitive bias that causes people to "see their own behavioral choices and judgments as relatively common and appropriate to existing circumstances". In other words, they assume that their personal qualities, characteristics, beliefs, and actions are relatively widespread through the general population.
In-group favoritism, sometimes known as in-group–out-group bias, in-group bias, intergroup bias, or in-group preference, is a pattern of favoring members of one's in-group over out-group members. This can be expressed in evaluation of others, in allocation of resources, and in many other ways.
Social comparison theory, initially proposed by social psychologist Leon Festinger in 1954, centers on the belief that individuals drive to gain accurate self-evaluations. The theory explains how individuals evaluate their opinions and abilities by comparing themselves to others to reduce uncertainty in these domains and learn how to define the self. Comparing oneself to others socially is a form of measurement and self-assessment to identify where an individual stands according to their own set of standards and emotions about themselves.
Sociometer theory is a theory of self-esteem from an evolutionary psychological perspective which proposes that self-esteem is a gauge of interpersonal relationships.
Attribution is a term used in psychology which deals with how individuals perceive the causes of everyday experience, as being either external or internal. Models to explain this process are called Attribution theory. Psychological research into attribution began with the work of Fritz Heider in the early 20th century, and the theory was further advanced by Harold Kelley and Bernard Weiner. Heider first introduced the concept of perceived 'locus of causality' to define the perception of one's environment. For instance, an experience may be perceived as being caused by factors outside the person's control (external) or it may be perceived as the person's own doing (internal). These initial perceptions are called attributions. Psychologists use these attributions to better understand an individual's motivation and competence. The theory is of particular interest to employers who use it to increase worker motivation, goal orientation, and productivity.
Self-evaluation maintenance (SEM) concerns discrepancies between two people in a relationship. The theory posits an individual will maintain as well as enhance their self-esteem via a social comparison to another individual. Self-evaluation refers to the self-perceived social ranking one has towards themselves. It is the continuous process of determining personal growth and progress, which can be raised or lowered by the behavior of others. Abraham Tesser created the self-evaluation maintenance theory in 1988. The self-evaluation maintenance model assumes two things: that a person will try to maintain or increase their own self-evaluation, and self-evaluation is influenced by relationships with others.
Self-enhancement is a type of motivation that works to make people feel good about themselves and to maintain self-esteem. This motive becomes especially prominent in situations of threat, failure or blows to one's self-esteem. Self-enhancement involves a preference for positive over negative self-views. It is one of the three self-evaluation motives along with self-assessment and self-verification . Self-evaluation motives drive the process of self-regulation, that is, how people control and direct their own actions.
In social psychology, illusory superiority is a cognitive bias wherein people overestimate their own qualities and abilities compared to others. Illusory superiority is one of many positive illusions, relating to the self, that are evident in the study of intelligence, the effective performance of tasks and tests, and the possession of desirable personal characteristics and personality traits. Overestimation of abilities compared to an objective measure is known as the overconfidence effect.
Envy is an emotion which occurs when a person lacks another's quality, skill, achievement, or possession and either desires it or wishes that the other lacked it. Envy can also refer to the wish for another person to lack something one already possesses so as to remove the equality of possession between both parties.
Herd behavior is the behavior of individuals in a group acting collectively without centralized direction. Herd behavior occurs in animals in herds, packs, bird flocks, fish schools and so on, as well as in humans. Voting, demonstrations, riots, general strikes, sporting events, religious gatherings, everyday decision-making, judgement and opinion-forming, are all forms of human-based herd behavior.
Social comparison bias is the tendency to have feelings of dislike and competitiveness with someone seen as physically, socially, or mentally better than oneself. Social comparison bias or social comparison theory is the idea that individuals determine their own worth based on how they compare to others. The theory was developed in 1954 by psychologist Leon Festinger. This can be compared to social comparison, which is believed to be central to achievement motivation, feelings of injustice, depression, jealousy, and people's willingness to remain in relationships or jobs. The basis of the theory is that people are believed to compete for the best outcome in relation to their peers. For example, one might make a comparison between the low-end department stores they go to frequently and the designer stores of their peers. Such comparisons may evoke feelings of resentment, anger, and envy with their peers. This bias revolves mostly around wealth and social status; it is unconscious and people who make these are largely unaware of them. In most cases, people try to compare themselves to those in their peer group or with whom they are similar.
The frog pond effect is the theory that individuals evaluate themselves as worse than they actually are when in a group of higher-performing individuals. This effect is a part of the wider social comparison theory. It relates to how individuals evaluate themselves based on comparisons to other people around them, and is generally due to upward comparisons toward people who are better than themselves.
Friendship jealousy refers to the type of jealousy experienced when an individual perceives a third-party threat to one of their valued friendships. It is not to be confused with envy, or wanting what a friend has.
