No, they aren't. They are the one chance we have to escape it.
You see humans are terribly biased. Racial bias isn't even anywhere near the strongest bias we have. Unattractive people get sentences twice as long as attractive people. Judges give far harsher sentences before lunch, when they are hungriest. Socially awkward people seem to be pretty strongly discriminated against. Studies have found people discriminate by politics even more than race. Job interviews have actually been shown to degrade performance over just judging resumes. Before statistics and credit ratings, getting a good loan required being an old friend of the banker.
It's not just that humans are unfair. We are objectively terrible. Very simple statistical algorithms beat human "experts" in almost every domain they get tried on. Way back in the 1920s, a statistician came up with a formula that was better at predicting recidivism than a group of 3 prison psychologists.
Simple linear regression has predicted the success of medical treatments better than doctors, diagnosed psychoticism better than trained psychiatrists, predicted academic success much better than admissions officers, predicted loan risk better than bank officers, etc, etc. To say nothing of modern machine learning methods on modern computers. It's insane we allow humans to continue doing these tasks at all.
But there has been huge resistance to algorithms in every domain. From people who stand to lose their jobs and be put to shame by them of course. But also even outsiders tend to reject algorithms. And overly trust humans. Psychologists have actually studied this. They call it a bias labelled "Algorithm Aversion". (http://opim.wharton.upenn.edu/risk/library/WPAF201410-AlgorthimAversion-Dietvorst-Simmons-Massey.pdf http://opim.wharton.upenn.edu/risk/library/WPAF201410-Algort...) The study showed that humans were willing to forgive the mistakes of humans far more than those of algorithms, even when the algorithm made far fewer of them.
This is why they aren't everywhere already. The last thing we need is fear mongering articles like this. As shown, humans are far worse. If an algorithm shouldn't do it, then a human certainly should not.
A big part of the case this article makes is a reference to a propublica study that found a slight bias against race in an algorithm once. Yet that study wasn't peer reviewed. The findings weren't statistically significant, which is a pretty low bar to begin with. And yet it always comes up as the main reference in these discussions. It's the only piece of evidence they can find of this nonissue ever happening. Stop. You are just making the problems you claim to care about worse.
- ivanbakel 9y agoThe bigger issue raised in the article is the idea that, even when algorithms are an "improvement" on human bias, the public is willing to accept that they express no bias at all. That level of trust in technology is unfair, and it doesn't exist for human judgement - if people are more confident in exercising oversight, that's at least one reason to not switch over to purely algorithmic decision-making.
