About the Technology
Data collected from customers, scientific measurements, IoT sensors, and so on is valuable only if you understand it. Data scientists revel in the interesting and rewarding challenge of observing, exploring, analyzing, and interpreting this data. Getting started with data science means more than mastering analytic tools and techniques, however; the real magic happens when you begin to think like a data scientist. This book will get you there.

In this unprecedented view from the trenches, prosecutor turned champion for the innocent Mark Godsey takes us inside the frailties of the human mind as they unfold in real-world wrongful convictions. Drawing upon stories from his own career, Godsey shares how innate psychological flaws in judges, police, lawyers, and juries coupled with a "tough on crime" environment can cause investigations to go awry, leading to the convictions of innocent people.
In Blind Injustice, Godsey explores distinct psychological human weaknesses inherent in the criminal justice system--confirmation bias, memory malleability, cognitive dissonance, bureaucratic denial, dehumanization, and others--and illustrates each with stories from his time as a hard-nosed prosecutor and then as an attorney for the Ohio Innocence Project.
He also lays bare the criminal justice system's internal political pressures. How does the fact that judges, sheriffs, and prosecutors are elected officials influence how they view cases? How can defense attorneys support clients when many are overworked and underpaid? And how do juries overcome bias leading them to believe that police and expert witnesses know more than they do about what evidence means?
This book sheds a harsh light on the unintentional yet routine injustices committed by those charged with upholding justice. Yet in the end, Godsey recommends structural, procedural, and attitudinal changes aimed at restoring justice to the criminal justice system.

Описание: In this unprecedented view from the trenches, prosecutor turned champion for the innocent Mark Godsey takes us inside the frailties of the human mind as they unfold in real-world wrongful convictions. Drawing upon shocking--yet true--stories from his own career, Godsey shares how innate psychological flaws and the "tough on crime" political environment specifically experienced by judges, police, prosecutors, defense attorneys, and juries can cause investigations to go awry, leading to the conviction of innocent people. Each chapter explores a distinct psychological human weakness inherent in the criminal justice system--confirmation bias, memory malleability, credibility-determining errors, tunnel vision, cognitive dissonance, bureaucratic denial, "group think" mindsets, and dehumanization, and then illustrates each human weakness with true stories from Godsey's time as a prosecutor and innocence lawyer. Part confessional, Godsey takes us back to his days as a hard-nosed prosecutor and brings to life the law enforcement mindset that leads to wrongful convictions in a way that has never been done before. It also analyzes the criminal justice system's internal political pressures. How does the fact that judges, sheriffs, and prosecutors are elected officials impact how they view cases, especially since re-elections are based on showing tough stance on crime? How can defense attorneys provide appropriate support for their clients when many are over-worked and underpaid? And how do juries overcome their own bias that those in power or influence--police, prosecutors, and expert witnesses--know more about what the evidence tells them? Godsey sheds a harsh light on the unintentional yet routine injustices committed by those charged with upholding justice. Yet in the end, he recommends structural, procedural, and attitudinal changes that can hopefully restore justice to the criminal justice system.
