Status Quo Bias
Status quo bias describes a systematic preference for the current state over a better alternative.
It's reinforced by loss aversion, anticipated regret and omission bias, which make action feel riskier than inaction and by default effects that lock in existing choices.
In practice this keeps people in tools, routines or projects that no longer fit.
Useful counters include creating better defaults (opt-in windows, scheduled reviews), running small reversible trials with clear stop rules, comparing options by expected value rather than comfort and writing change criteria in advance to reduce after-the-fact justifications.
