I work at a retail store where every error is as generic as it can be "Authorization declined" for example. It could mean... -Wrong PIN -No Balance -Chip was bumped -Card was used out of state It's very frustrating to me AND customers.

[@encycl07pedia-]

What's worse is when idiot programmers decide error codes are a good idea after 1980. Error code: 123984JRH. You have to search it. Oh, this means you may have one of ten different issues! Netflix is one of those. Just tell people the actual error. And don't get me started on the error messages that are just plain wrong. It's infuriating as a programmer when you fix the problem stated in the error message and get the same error message because the monkey who designed it was too myopic to see any cases where something else could cause that error to occur. Those are arguably worse than just sitting and waiting on an error code that may never come (looking at you, noscript-less pages).

A couple of years ago I started having alarming neurological symptoms. After many tests and scans I got a call from a specialist who would be taking over my case. At this point I still had no idea what was going on, so I called the number to set up an appointment. The words I was greeted with filled me with dread. "Thankyou for calling neuro-oncology, can I help you?" It turned out that because of a rare genetic disorder I have I was referred to a doctor who had a subspecialty in this disorder, his main specialty was neuro-oncology. So I didn't have brain cancer. But of course the receptionist who set up my appointment couldn't tell me this, so I spent about a week thinking I was going to be getting very bad news indeed. It was very stressful. I mentioned this to my doctor and for some reason they stopped greeting people with that greeting. I mean, a lot of the people calling that number probably do have brain cancer, and you don't want to find this out with a cheery "Thank-you for calling the brain cancer treatment doctors"

With a system that public, it should at least have a generic message as part of the catch-all. "We're sorry, the automated system has experienced an issue accessing your data. Please stand by while we connect you with one of our team." It's always worthwhile to handle edge cases. The only question is: Do you handle them individually, or do you use one giant generic error handler?

[@ZipplyZane]

And now I'm gonna erase my post saying the same thing.

[@MedoFortyTwo]

IMO, handling errors well is one of the most difficult aspects of programming. My rule of thumb is: individual messages / solutions for "business domain" problems that the user can understand ("The selected seat has been reserved by someone else in the meantime. We have updated your seating plan, please try again."), one general message / solution for technical problems like database trouble or unreachable services or anything else not in the user's domain ("Your reservation could not be processed due to a technical problem. We have already been automatically informed about the issue. Please try again at a later time.") Assuming a typical logging mechanism is in place, technical problems should always be internally logged as errors with internal details of what went wrong, so that the system operator can be notified and so that programmers can figure out the issue. Business domain problems should not usually be logged above info level because they don't indicate that the system is malfunctioning, so they would just create noise for the system operator to sift through and ignore. In the system Tom describes there was apparently a general solution for technical problems and it was even a sensible one (the system didn't just e.g. tell him there was an error and hang up, though that would have been easier on people's nerves). The only issue is that it initially looks to the caller like the "bad news" case.

[@alexm7307]

How's this: if (positive) { //sucks to be you announce(callTransfer); call.transferToRealPerson; } else if (negative) { announce(resultsNegative); call.hangUp; } else { announce(oopsieDoopsie); call.transferToRealPerson; KZbin.subscribe("PewDiePie"); //I am doing my part! }

As a software developer of 45 years experience working on IBM Midrange and Windows systems, I give you big "KUDOS" for this post. One of the most important lessons I ever learned was that chiefly, I am a tool maker. I make tools that other people have to use to do their jobs. 'Good enough' is never good enough.

[@nekomatafuyu]

If there was a different message for an error compared to a positive test result, then the message for the positive test result would effectively be the computer telling you the bad news. By the sounds of it, the problem wasn't so much with the code, but with telling the patient that there will be a difference in how the message is delivered depending on the test result - The given method basically results in the patient being told of a positive result by a computer whilst stating that the whole point of the system is that a patient should not be told of a positive result by a computer.

[@spiltcore]

That's what I dipped into the comments to say, i.e. the alleged programming error has the effect of keeping uncertainty (and hope) alive until there's definitely a human available to talk. Thank you for being onto it already.

It’s possible that that was intended behaviour, had they publicised the fact that some negative test results are randomly put through to humans it would cause people to panic less when they’re put through to humans. This may have been a mistake in the PR not the code.

[@NFMorley]

Sounds possible - especially as people may have follow up concerns so having occasional calls forwarded to specialist nurses might help catch health trends sooner (or just act as a blind control on whether the system/model works - ie if more aftercare, support, etc is needed)

[@loopback36]

Why you're not higher in the comments? That was my thought too

[@nebuleon]

@@NFMorley I have a feeling that a random sampling sent on purpose to humans would not have experienced the absurd pause Tom got on the line, though. (And I don't know how the system usually works; I'm not in the UK. Maybe there actually is a lengthy pause for everyone.)

[@Showsni]

I was thinking that too - if every single negative result puts you through to a human and every single positive result doesn't, then there's no difference in having the machine announce you failed the test.

[@slackius851]

Came to look through the comments to see if anyone else had this same thought. If this is what’s happening, there should be more information given to people saying so. Leaving that out only decreases the effectiveness of such a design decision. That said, I can see such a change being made after the system was already in place. That’s a recipe for half-baked implementations like this one just to fulfill the new requirements and nothing more. This kind of “fix” might even be as simple as changing some numbers or clicking a checkbox. If that’s the case, I can see why no further effort would have been made to record more informative messages.

[@o0Avalon0o]

My friend just casually mentioned they just had that test months ago; I asked if they ever got results back. They said they never got contacted so they assumed it was negative... I helped them sort it out but that did not mean negative.

it's not only for those errors caused by edge cases, tho. it's also about people whose devouted enough to abuse it and sometimes people are lazy or don't have enough time to do such thorough debugging. And sometimes such weaknesses came inherently from the platform that the code stood upon.

I used to work with a developer named Charlie. "Charlie's Law" was if it takes 1 unit of time to develop code for "me", it takes 3× time to develop code for "us" (the team, a group of coworkers) and 3× that amount of time to make it work well enough for "everybody." I think this is reasonably accurate.

I think it would be a good thing to make it so that it always puts you through to a human, no matter whether your result is good or bad. If it's only supposed to put you through for bad results, then that means it just drags out the reveal and makes it even more uncomfortable experience. Either way, I get exactly what you're saying about that long awkward pause. It's like some kind of super-evil version of Chris Tarrant waiting almost a minute to reveal the correct correct answer after the contestant has said final answer.

Very good video. I'm in the field of information security and it's very, very clear from my perspective that the vast majority of security problems are caused by the exact same "good enough" attitude and wouldn't exist if someone had spend a bit more care and - that's the problem - resources on thinking about unintentional consequences. We've now spent the past 20 years trying to cope with this, with ever better technologie, with better management approaches, with complex risk assessments - but rarely do we do anything about the root cause. It's a case of the insane running the asylum.
