Cory Doctorow explains why so many of us have gotten into the habit of oversharing personal details in our social media activities:
Whenever government surveillance is debated, someone inevitably points out that it is no cause for alarm, since people already overshare sensitive personal information on Facebook. This means there’s hardly anything to be gleaned from state surveillance that isn’t already there for the taking on social media.
It’s true people overshare on social networks, providing information in ways that they later come to regret. The consequences of oversharing range widely, from losing a job to being outed for your sexual orientation. If you live in a dictatorship, intercepted social media sessions can be used by those in charge to compile enemies lists, determining whom to arrest, whom to torture, and – potentially – whom to murder.
The key reason for oversharing is that cause and effect are separated by volumes of time and space, so understanding the consequences can be difficult. Imagine practising penalty kicks by kicking the ball and then turning around before it lands; two years later, someone visits you and tells you where your kicks ended up. This is the kind of feedback loop we contend with when it comes to our privacy disclosures.
In other words, you may make a million small and large disclosures on different services, with different limits on your sharing preferences, and many years later, you lose your job. Or your marriage. Or maybe your life, if you’re unlucky enough to have your Facebook scraped by a despot who has you in his dominion.
