In almost any data-gathering situation, there are far more types of information that could be gathered than you can possibly tackle. Compare the contradictory claims that U.S. wireless phone providers make for their network coverage. No one's lying--they're all just picking different aspects of coverage to measure. Are you measuring it accurately? There are far more ways to screw up a measurement than there are to get it right. Ever compare election results to what the polls had said right up to the end? And political pollsters are the rocket scientists of data gathering--it's downhill from there. Are you interpreting the data wisely? Unless someone is inside trading, all inve...

As Robots come into play more and more, the person who codes them can become the double bluff.  Trick you with emotions of love and steal your wallet in the process. Don’t believe me then watch – Guy Hoffman: Robot...

We studied the group of people who changed their status from "Single" to "In a relationship" and also stated an anniversary date as the start of their relationship. During the 100 days before the relationship starts, we observe a slow but steady increase in the number of timeline posts shared between the future couple. When the relationship starts ("day 0"), posts begin to decrease. We observe a peak of 1.67 posts per day 12 days before the relationship begins, and a lowest point of 1.53 posts per day 85 days int...
