The French philosopher Michel Foucault (1926-1984) has a set of insights that can help clarify how social media affects us on a psychological level. Foucault died before the advent of the internet, yet his studies of social conditioning and identity formation in relation to power are applicable to life online. Seen from a Foucaultian perspective, social media is more than a vehicle for exchanging information. Social media is a vehicle for identity-formation. Social media involves ‘subjectivation’.
