My latest Guardian column "Surveillance: You can know too much," explains how collecting too much information on innocent people makes it harder to catch guilty ones:
At a certain point, data gathered to predict the weather overwhelms your capacity to add it to your calculations efficiently, resulting in ever-longer runtimes that give less accurate predictions. It's better to crunch the data needed to calculate tomorrow's weather in 10 minutes (and refine your guess twice an hour) than to shovel so much data into the hopper that you don't get tomorrow's forecast until next week.
The sweet spot lies somewhere between gathering too much information and gathering too little – and the secret to hitting that spot is intelligent, discriminating data-acquisition.

One way your score can be plunged into negative territory is for a judge to declare you to be a bad person (mostly this happens to people said to have refused to pay […]
