Hello World: Being Human in the Age of Algorithms
von Hannah Fry
Unless the fraction of people who commit crimes is the same in every group of defendants, it is mathematically impossible to create a test which is equally accurate at prediction across the board and makes false positive and false negative mistakes at the same rate for every group of defendants. It’s like the saying among airline pilots that the best flying team has three components: a pilot, a computer and a dog. The computer is there to fly the plane, the pilot is there to feed the dog. And the dog is there to bite the human if it tries to touch the computer.

Just by virtue of some algorithms existing, we face issues of fairness that cut to the core of who we are as humans, what we want our society to look like, and how far we can cope with the impending authority of dispassionate technology.
There are two parallel threads of human error here. First, someone wrote this garbage spreadsheet; second, others naïvely trusted it. The ‘algorithm’ was in fact just shoddy human work wrapped up in code.
That was the deal that we made. Free technology in return for your data and the ability to use it to influence and profit from you. The best and worst of capitalism in one simple swap.

"Forming an opinion on an algorithm means understanding the relationship between human and machine. Each one is inextricably connected to the people who build and use it."
"It would probably be more useful to think of what we’ve been through as a revolution in computational statistics than a revolution in intelligence."
