The back end of the worst week you’d had, and you find yourself looking at venues. Or house prices. Or working out whether you could go part time so there’d be less to argue about. Not leaving. Investing.
Escalation of commitment is one of the most replicated findings in decision-making research: the more someone has already put in, the more likely they are to keep going, even when the evidence says stop. The decision stops being about whether this is good and becomes about not wasting what’s already gone in.
And a coercive relationship actively increases what you’ve invested. Isolation removes the alternatives. Financial entanglement raises the exit cost. Having your reality overwritten means less confidence in the evidence that says leave. The conditions that make this bias strongest were being built around you the whole time.
