Self-reinforce
A process where an initial effect strengthens itself by creating conditions that amplify the same effect. In social contexts, this often becomes a feedback loop where negative information or a trend intensifies because it reinforces its own presence.

A process where an initial effect strengthens itself by creating conditions that amplify the same effect. In social or environmental contexts, this often manifests as a feedback loop where negative information or a trend becomes more intense because it reinforces its own presence. For example, avoidance of news can increase anxiety about bad news, which in turn leads to further avoidance, creating a self-perpetuating cycle.
What this means in real life
A runner who finishes a morning jog and immediately feels proud, then posts about it online for likes—the pride and social validation reinforce the habit, making them more likely to run again tomorrow.
What it isn’t
It is not the same as self-discipline or willpower. Self-reinforcement is about strengthening behavior through reward or confirmation, whereas discipline is about forcing yourself to do something despite resistance or lack of immediate reward.
Commonly misused online
Often conflated with 'toxic positivity'—people assume any self-reinforcement is healthy. In reality, reinforcing harmful beliefs (like conspiracy theories through echo chambers) or unhealthy behaviors (like perfectionism through constant self-praise) can be destructive.
