The vanishing cost of guessing
[C]ritics charge that big data will make us stick to constantly optimizing what we already know, rather than thinking out of the box and truly innovating. We’ll rely on machines for evolutionary improvements, rather than revolutionary disruption. An abundance of data means we can find facts to support our preconceived notions, polarizing us politically and dividing us into “filter bubbles” of like-minded intolerance. And it’s easy to mistake correlation for causality, leading us to deny someone medical coverage or refuse them employment because of a pattern over which they have no control, taking us back to the racism and injustice of Apartheid or Redlining.
