I’ve been thinking about human behaviour. And to me it seems that our brains invoke a “default action” or a “default network” when there is no actionable stimuli or a task or actionable goal at hand. Is there such a thing in psychology?

For example if I complete a task and don’t have anything else to do this second I fall back on a default action. This action is dependent on the situation. This action is something that I usually do in a similar situation.

This can be harmful if you are addicted to something. You seek out your addiction. The default action can overridden. But it requires effort. Default action does not. In case of addiction the required effort can be overwhelming. But if you can override the default action again and again the new action becomes the default action in that situation.
