Crab mentality is basically “if I can’t have it, you or nobody can.” When a group of crabs is trapped in a bucket, one crab may easily escape, but the others would aggressively drag it back down. Humans are not that different from animals. The crab mentality happens almost ubiquitously. When an individual’s success or elevation threatens group dynamics, the collective often chooses containment or sabotage over celebration.
Interpersonal sabotage
Because this mentality thrives on similarity or shared identity, you don’t feel crab mentality toward a celebrity or billionaire (unless you are one of them). Instead, you feel it with people who were in the same place. This is especially true in more intimate settings, such as friendship or a romantic partnership.
Imagine one friend starts exercising, eating healthy, studying for a new career, or promoting. A healthy friend circle celebrates, encourages, and inspires each other. A dysfunctional “friend”, conversely, uses peer pressure, passive-aggressive mockery, and exclusion to pull the person back. Because the individual’s improvement highlights their own stagnation, they think, You think you are better than us? I won’t rest until you lose that thing I want but don’t have.
Likewise, if one romantic partner has a breakthrough, the partner may minimize the achievement, dismiss their feelings, pick fights on the day of big interviews, or create emotional chaos to drain the achiever’s energy.
Professional group dynamics
While interpersonal-level exploitation is outrageous, this belief often manifests in groups where people compete for limited resources.
“Tall Poppy Syndrome” is commonly talked about in UK, Australian, and New Zealand sociology. If someone becomes too powerful, the public or the media look for flaws to humiliate them. This might be a situational, careless mistake from ten years ago, yet the goal is simply to bring them down. You’ll also see this a lot in academia or corporate settings. A student who shows outstanding talent is mocked as a “nerd.” Or bullies isolate them, start a smear campaign, or accuse them of “intentionally making others look stupid.” Or coworkers collectively isolate an overachieving employee, sabotage their projects, or ruin their reputation.
Ultimately, high performance makes the rest feel and look incompetent.
The psychology behind crab mentality
The most straightforward explanation is envy: benign envy may involve wanting what others have and learning from it, while malicious envy (the one behind the crab mentality) drives people to want others to lose what they have. Moreover, relative deprivation is another factor. If you and your friend earn $50,000, you’re equals. But if one starts earning $150,000, your relative status plummets, even without any change in your lifestyle. If it happens in a group, someone’s success may challenge everyone else’s excuses: you can no longer blame the system, bad luck, or other environmental factors (unless everyone is trapped).
While most people feel the damage as direct interpersonal sabotage, the real danger is internalized “self-crabbing.” If you sabotage your own achievements out of fear of retaliation or isolation from your peers, you deserve a better circle. Leave them alone. Let them. (Related: Why Are People Trapped in a Dysfunctional Social Circle?)
