This, I think, is one of the most important books I've read this year. For, one cannot expect to grasp even the most sketchy outline of our socio-economic reality if one is not familiar with the now-prevailing currency, namely data.

Computer is good at doing things fast, really fast. So, when it errs, it errs like the flash, resulting a gigantic accumulation of errors. It shouldn't be surprising that big data (a match made between statistics and computer science) with its inbuilt measures of inaccuracies paired with shortcomings in creating mathematical model that sufficiently mirror the reality will create tools of horrible injustice.

However, it is not always easy to notice. Technical difficulties and self-fulfilling feedback loop can deceive us quickly.

However, the writer herself have has been deep in this systems and saw these things closely. With her deep knowledge and a very conscientious mind, she is well equipped to discuss the matter in great depth and honesty.
