Psychologist Michal Kosinski developed a method to size up who a person based on their FB activity.

If you would like to get a small taste for what companies can do with Big Data, follow this link to Kosinski’s own website (found in the above article). I did this, and I was impressed. Based on 60 of your FB “likes,” a company can get a impressive read on who you are.

This is not just a parlor trick. This type of analytics can swing a tight presidential election.
