Why do you keep the plan you have even when a better one is right there?
Doing nothing feels safe, so "leave it as is" quietly wins arguments it never earned.
Status quo bias is the pull toward keeping the current state of things just because it is the current state. When one option is framed as the existing default, far more people pick it, even when a different option would serve them better. Switching forces an active choice, and if that choice goes wrong it feels like your fault, so the safe move is to change nothing.
Your phone plan quietly costs more than three newer plans, but you have stayed on it for two years because cancelling and comparing feels like a hassle.
Standing still is a decision too, and it is the one we make by accident most often.
Once a month, audit one thing you are on autopilot with - a plan, a habit, a subscription - and ask if you would actively pick it again today.
Status quo = the default wins by walkover, not by winning.
