An interesting read over at Aeon about our innate sense of privacy and how it affects what we do online.

Too much information: Our instincts for privacy evolved in tribal societies where walls didn’t exist. No wonder we are hopeless oversharers

Over time, we will probably get smarter about online sharing. But right now, we’re pretty stupid about it. Perhaps this is because, at some primal level, we don’t really believe in the internet. Humans evolved their instinct for privacy in a world where words and acts disappeared the moment they were spoken or made. Our brains are barely getting used to the idea that our thoughts or actions can be written down or photographed, let alone take on a free-floating, indestructible life of their own. Until we catch up, we’ll continue to overshare.
