Amazon 'Reviewing' Its Website After It Suggested Bomb-Making Items (nytimes.com)

An anonymous reader shares a report: Amazon said on Wednesday that it was reviewing its website after a British television report said the online retail giant's algorithms were automatically suggesting bomb-making ingredients that were "Frequently bought together." The news is particularly timely in Britain, where the authorities are investigating a terrorist attack last week on London's Underground subway system. The attack involved a crude explosive in a bucket inside a plastic bag, and detonated on a train during the morning rush. The news report is the latest example of a technology company drawing criticism for an apparently faulty algorithm. Google and Facebook have come under fire for allowing advertisers to direct ads to users who searched for, or expressed interest in, racist sentiments and hate speech. Growing awareness of these automated systems has been accompanied by calls for tech firms to take more responsibility for the contents on their sites. Amazon customers buying products that were innocent enough on their own, like cooking ingredients, received "Frequently bought together" prompts for other items that would help them produce explosives, according to the Channel 4 News.

    If that's the case, then it's not a problem. You're just showing ads for plastic buckets to people who don't want to build a bomb. I suspect the worry is that the algorithm might actually be working. In which case it's still not a problem. Once you have the recipe for a plastic bucket bomb, finding the bucket isn't a major obstacle.

      I don't understand how this isn't just Amazon showing articles from a hardware store, rather than, well gee there are soooo many people making this stuff that the algorithm has learnt the specific components.

      You would think they would be more concerned with why so many people are buying these items together that the algorithm is showing them as frequently bought together.

      The surprising thing is that enough people were buying bomb-making ingredients together to train their algorithm. Most things that you use to make bombs are dual-use items, and I'd expect a lot more people to have been buying them to not make bombs than were buying them to make bombs.

      Exactly, the algorithm is working perfectly. Since people aren't blowing up buildings left and right and yet are making bomb making stuff, maybe the people in the UK should work on desensitizing themselves to things that are done a regular basis both for practical reasons and recreation. Here in the US (where Amazon is based) we have a massive rural population and blowing stumps and the like is just daily life for those folks. For most things that is just fine and legal so long as they don't transport and for things where it isn't entirely legal... lets just say if he isn't getting anything too crazy, stockpiling anything, or hurting anyone then whatever levy Farmer John is moving or refrigerator he's blowing up on his back 40 or personal firing range is somewhere near the bottom of the list for federal agents, especially since he has a legitimate reason to buy big bags of fertilizer and large quantities of diesel and it isn't the easiest thing in the world detect if he were using something a big bigger to blow a stump.

      Well, I suppose this is an occasion for Bayesian reasoning. The probability that you buy bomb ingredients given that you're a terrorist being high doesn't mean that the probability that you are terrorist given that you buy bomb ingredients is necessarily high. In fact even if someone is *definitely* building a bomb, it doesn't automatically mean they are a terrorist.

      On YouTube there's a whole genre of videos devoted to large Tannerite explosions. Tannerite is an impact-initiated binary explosive that is popular for making shooting targets. Normally it's used in small quantities but of course there are many videos of people setting off very large Tannerite explosions, involving hundreds of pounds of the stuff.

      Some people are just fascinated with explosives. So what you have to ask is whether it is more common to be into blowing things up for DIY amusement or blowing things up to hurt people. Where people go wrong with this kind of question is they rely on their intuition in guessing prior probabilities. If blowing things up holds no fascination for them, they assume that that kind of thing must be rare, or even non-existent.

    Looks like you're building a pipe bomb. Would you also like some acid to throw in white women's faces in case it doesn't go off? How about a fidget spinner in case both of your attacks fail?

    In recent days amazon has been found to be deleting reviews of Hillary Clinton book that are negative - they justify this by saying that "no one could have read the book that fast" yet they don't block the great reviews from people who have had the same amount of access to the book as the negative reviewers.

    If you take away the ability of people to speak freely, leaving them with the perception of censorship***, they will find other, very terrible ways to communicate their thoughts...and suggesting bombs at the same time is something that is actually genuinely frightening.

    ***I know amazon is not a government and therefore cant "censor" but it can give the perception thereof because of the sheer power they do hold.

      That's not accurate - it seems they removed non "Verified Purchaser" reviews, which were predominantly one star; it does seem likely that most of those people might not have read the book, and certainly they didn't get it from Amazon. From Slate:

      Amazon has since removed hundreds of reviews—both positive and negative—from unverified reviewers, but since these were overwhelmingly in the one-star camp, the book’s rating has now jumped from a 3.2 rating to a 4.9 rating overall.

      Amazon has been deleting negative reviews from people it can't verify have bought the book from it. That's entirely reasonable - the book is being review bombed heavily, and the goal is to provide reliable reviews (it's not your political free speech soapbox).

      There are plenty of people who have bought the book from Amazon, had time to actually read it and decided to leave a review. Not all of them are positive, but the barrier to entry (the cost of the book + time) does mean that people who review it are at least interested in the content.

      They are doing the same thing with Zoe Quinn's new book. Steam is doing something similar with game reviews, because people review bomb them in response to some random thing the developer posted on Twitter.

    The algorithm isn't faulty. It works exactly as designed. But it is also completely blind to the deeper meaning of the result. Take this as a cautionary tale against all software-augmented decision making. Software is not inherently fair and impartial. It just blindly follows a rigid set of rules that don't include any moral values. And sometimes, the developer may have even made the rules intentionally malicious.
