Changes in behaviour  Surveillance changes the way we make daily decisions—the same way that a rapidly approaching police car in your rear-view mirror may make you feel nervous even when you are driving completely lawfully. The very existence of a mass surveillance system will negatively influence the behaviour and emotions of a significant majority of the population.  First, surveillance affects emotions and mental performance, as it leads to heightened levels of stress, fatigue and anxiety due to the constant feeling that you are being watched.(1)  Secondly, it creates conformity to social norms. “In a series of classic experiments during the 1950s, psychologist Solomon Asch showed that conformity is so powerful that individuals will follow the crowd even when the crowd is obviously wrong. A government that engages in mass surveillance cannot claim to value innovation, critical thinking, or originality.”(2)  This is of extreme importance as first of all, it is the state’s duty to create the most peaceful and harmonious environment in which the individual can reach its full potential (this one clearly not being it) and second if we don’t feel free to do things that are perfectly legal because we think someone might think it suspicious or out of character then it is difficult to say we are really free.
