How the internet can read your mind

Short cartoon video on the subject of deduction by computers of your friends, habits and messages in order to read your mind

Think you can hide your personal data by choosing not to reveal information online?

Even if you’re a social media prude, advanced software algorithms can glean a surprising amount of detail about your life. For example, even though most people on Facebook choose not to reveal their physical addresses, it’s possible to infer the general location of the majority of users based on the few who do. Similar software can figure out who is likely to be your friend and what kind of personality you might have.
