Why does it seem that people behave like they are supposed to when they are being observed?
For example. If you place a fake security camera on an employee, they would behave better (or at least appear to).
Alternatively, when a system or workflow becomes transparent, it seems to me that people would make an extra effort to do better since they are more exposed.
Is there any particular identified effect, cognitive bias, or phenomenon that describes the reasons behind this change of behavior?
