Amazon 'Reviewing' Its Website After It Suggested Bomb-Making Items (nytimes.com) 156

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.

      • I think what is freaking people out is that it's all but literally telling you the recipe, and doing so across a pretty wide spread of departments. For example, if you go to buy Red Iron Oxide powder (Common supply for pottery and ceramic hobbyists), it suggests also buying aluminum powder and magnesium ribbons from way over in "Industrial and Scientific," which is all you need to mix and ignite thermite. The worst example was where stump remover suggested you buy the other ingredients for homemade black

      • This story is a bit misleading and sensationalist. The "gunpowder" they refer to isn't anything any modern gun would use. It's not nearly so strong. Instead it's the raw ingredients for the centuries-old black powder, which needs extensive processing in order to make black powder from these ingredients. Just mixing them will do nothing. (I've made black powder multiple times, using ingredients from the hardware store.)

        The other item they refer to as "explosive" is metal powder, which Burns with a bright li

    • But it's the PR perception that Amazon is encouraging folks to buy all the bomb making materials a terrorist needs in one go that they are trying to avoid. That the algorithm works and apparently creates more sales and more happy customers is not the issue.

        • That's another way of making my point. Amazon's goal is to sell stuff, as much stuff as they can. They only care about this because the bad PR reduces sales..

      • I know you capitalized all the letters in LITERALLY, but there are still products that Amazon doesn't sell. So, it's not 'literally everything.' I'm not sure that negates your point, but hyperbole is dishonesty and being dishonest reduces the value of your speech.

      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.
      • by SeaFox ( 739806 )

        It's much easier to push around online retailers than to look for solutions to social problems that breed terrorism to begin with.

      • Because blowing shit up is a lot of fun and not necessarily harmful. I doubt the majority of these purchases are made for any reasons that are harmful. There's not much out there that is more entertaining than blowing shit up. It's even possible to blow shit up without hurting yourself or anyone else. Hell, you can blow shit up and be apolitical.

      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.
      • by hey! ( 33014 ) on Wednesday September 20, 2017 @11:14AM (#55232001) Homepage Journal

        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 [youtube.com], 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.

        • Thinking about it a bit more, Amazon does tailor the recommendations to you, so maybe the people who are complaining are ones that the recommendations algorithm has decided are terrorists.

      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.
    • The real problem is that in order for the algorithm to work, there have to be enough people out there who are in fact buying the items together. Either those items are often bought together for some other non-bomb-making purpose -- people buying plastic buckets, nails, engine oil and high-nitrogen fertilzer because they are DIY gardners who are working on a shed to hold their lawnmower -- or there are enough people out there building bombs with ingredients purchased together on Amazon that their algorithm

    I suspect most of these suggestions are based on actual purchase histories or at least browsing histories--these are data trends. What does this say about consumers?

    I highly doubt Amazon hired staff to curate product groupings since that's not feasible for all products. These are data trends and Amazon is simply displaying them. Now, Amazon has to go in an *actually curate* nasty product grouping relationships to create an exclusion list. Damned if you do, damned if you don't I suppose.

    • Doubtful. Amazon's algorithm is terrible. Mainly it is looking for things that it thinks are associated, upsells, or ads.

    If so, that should be a big clue as to who is building them.

    You can still get "The Anarchist Cookbook" [amazon.com] on Amazon, which is the number one bestseller in Anarchism.

      • by gweihir ( 88907 )

        Pretty much anybody that tries to make more historic (and easier to make) explosives for the first time finds this out. The stuff is dangerous. There is also a (IMO credible) rumor that the CIA actually published this book and the recipes are just recipes that are public anyways but all the safety-precautions have been removed. I find that credible, and if true, the CIA would have done good for a change.

        • The good thing to do would be to collect intelligence on suspects, hand the information to the police who then arrest them, not to cause kids in the whole world to blow their hands off.
          • by gweihir ( 88907 )

            I, on the other hand, like a bit of evolutionary selection for intelligence here. Gross stupidity should come with significant personal risks. And when they actually intended to blow up other people, poetic justice comes into it as well. Also note that stupid "kids" manage to maim themselves (and others) all the time via things like drunk driving, for example.

            • Jerry Pournelle (RIP) managed, at the age of 14, to make "about half a cup" of nitroglycerine without blowing himself up. The recipe was right there in the Encyclopedia Britannica, and the ingredients easily obtained by a 14-year old farm kid in rural Tennessee in the 1940s. That took some smarts. The stupid ones trying the same would have atomized themselves.

              The hog pond would never be the same again, though.

    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.

      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.

      • Isn't it trivial to only allow people who have purchased said product from Amazon to review said product (once)?

        • It is, Amazon has instead chosen to mark those reviews from people to whom they know they have sold the product differently from other reviews, because they want reviews even if they are of low-quality because they can point to $BIG_NUM of reviews and say "look how credible we are"

        • For some products, I imagine that they will take whatever reviews they can get. There may just not be enough verified purchasers out there. After all if Amazon just started carrying a product, they won't have any verified purchasers. So they have to accept any reviews. Once there are enough sales (assuming the initial reviews were positive enough to generate any), they may want to switch to verified purchaser reviews.

    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.

        ..oh, and would you like a text message sent to your phone (*ahem* any phone you like) when it's 'delivered'?

      Running low? Just hit the button and your frequently ordered item will be there in a Dash!

      Think Amazon for all your Jihadi needs.

Absolute ignorance. somewhere around the fifth grade bright students are able to put together various facts that enable bomb building and frankly they don't even have to buy anything suspicious. And Lord help you if you have an eighth grader with a strong interest in chemistry. The only answer is to keep all people in absolute ignorance and spy on them in their homes relentlessly.
  • Finally one supplier cares about what the demand side is actually demanding and of course those damn commies have to put a stop to it!

    Stop interfering with free trade, dammit!

  • It is fun when you look at items like precision scales to see all the drug-related stuff being suggested. Usually that's for cannabis, but not only.
