But the effect isn’t pretty. Under depletion’s influence we are more prone to inappropriate social interactions, such as talking too much, sharing intimate personal information, and being arrogant. We are less likely to follow social norms; for example, we are more likely to cheat. We are less helpful. We can also be more aggressive; the effort of curbing our normal aggression depletes our self-control over that impulse. Conversely, we can also be more passive; when our intellectual resources are sapped, we are more easily persuaded by others and less adept at coming up with counterarguments.
