The problem with predictions is that it uses past data. People evolve their strategies, which invalidates the prior knowledge.
The leftist technocrat really believes that if only they can capture and evaluate all the data then they can do a perfect job of central planning.
The leftist technocrat sees the BIG DATA fad of current IT as the solution to their prayers.
Take the recent superbowl. At halftime most people were predicting Atlanta would win. Then early in the 3rd quarter 2 things happened that made Brady and Bellicheck know that they would win the game.
An Atlanta player sauntered into the end zone as if he were playing against amateurs. Then Atlanta special teams recovered an onside kick. The body language of the young players on the sidelines said they thought they had already won the game and did not need to try anymore.
Now all the technocrat needs to do is acquire complete information on the psyche of each player and collect complete information on the group dynamics mass psychology and feed that into the model and then they can accurately predict the outcome of the game.
Eventually Big Data and Analytics will be even smarter than Tom Brady and Bill Bellicheck... that is the belief of the Leftist technocrat.
