Looking at these in isolation might give some the mistaken impression that these instances of workplace sexism and harassment are isolated incidents. When viewed as a whole, it's clearly a problem for software engineering (as people in the field have been claiming for years). In fact, I'd be willing to bet that we'll soon see comments full of anecdotes from people who have never seen sexism or this kind of harassment in their workplaces claiming that there is no problem. Or implying that this is somehow not all bad. For sure this is an issue in many fields, but software engineering seems to be the only one in which people proudly proclaim there is no problem, despite the increasing number of reports to the contrary.

> I'd be willing to bet that we'll soon see comments full of anecdotes from people who have never seen sexism or this kind of harassment in their workplaces claiming that there is no problem. I think this happens because people generally believe that a anecdote confirming the null hypothesis serves as evidence for that hypothesis. It's one of the best examples of something that scientists, engineers, and so-called "logical" thinkers screw up on a day-to-day basis. In other words, suppose I claim that some days a subset of the population can see the earth's sky as green, rather than blue. My null hypothesis in this case is that the sky is blue and always will be for all people at all times. Finding several anecdotes from people who have seen the sky blue can never confirm my null hypothesis. They may have simply never seen the sky green. In statistics, we can sort of work around this problem with p-tests or confidence intervals. In interactions with normal humans, I like to take the personal approach of always putting a little more weight in anecdotes that push against the null hypothesis. Just because they're contrarian, it doesn't mean their argument is more valid, but when you encounter something "outside of the norm" it's worth evaluating whether your sense of "normal" is more biased than you might think.

  Erm, what? Encountering normalcy is evidence for things being normal. It might be weak evidence - after all, the "sometimes some people see the sky green" also predicts a lot of sky-looks-blue. But it's still evidence, you can't just throw it out because you've labeled it the "null hypothesis".

    I'm not saying you throw it out. Read more carefully, don't put words in my mouth please. > Finding several anecdotes from people who have seen the sky blue can never confirm my null hypothesis were my words exactly. May I ask what issue you take with this wording? In your counter, you misinterpreted this and claim that I throw evidence out. My actual claim is such anecdotes actually do not serve as well as evidence. As you said, you cannot throw out such evidence, and I agree. You seem to have misunderstood what I meant. More importantly, you then fall prey to the exact logical fallacy I'm discussing while trying to counter me: > Encountering normalcy is evidence for things being normal False. False. False. False. This is legit the encapsulation of what makes this a fallacy. Consider the following thought experiment: Suppose I give you a black box, and I ask you to prove to me that this machine works perfectly. You sit down and watch the machine, and you can verify that it is working perfectly right now. It is now logically impossible to prove the machine works perfectly at all times, however, because you lack any evidence the machine does not operate normally. You could watch the machine all day, and all night, for eternity, till the stars die in the sky. At any point while watching it, would you claim that you now have evidence the machine always operates normally? How do you know I haven't programmed it to break the instant you turn away from it? Or the instant you stop observing it? There's no way to know for sure...so do you have any evidence it's performing perfectly? Anecdotal evidence is very similar. Many anecdotes re-affirming that all is working as planned don't tell me anything because that is the "null hypothesis". I take issue with your wording "because you labeled it the null hypothesis". I didn't label one or the other maliciously or even intentionally. The definition of the null hypothesis is (in my experience, I'm not a mathematician by trade) the scenario which is the "default" or "normal" or "expected". This fits both the scenario I gave and the analogy I make. Again, I'm not saying I'm "throwing out" such evidence. In actual human interactions, we cannot swing the pendulum entirely the other direction and simply ignore and throw any evidence that confirms the "normal" either. In such a case, we would be making the exact same logical error except in reverse. I'm just trying to point to a general guideline based upon statistics and our usage of the null hypothesis within it. Mathematical ideas do not map perfectly to worldly ones, but they serve as useful tools and models. In this case, I use my model to remind myself to consider anecdotes that are "abnormal" or "beyond the norm" as more important evidence since these "abnormal" events are the very things I want to be able to recognize. A more rough "human" example might be: Say you give your cancer test results to five random doctors, and 4 of them say you're okay as expected, but one says you have cancer. My point is that the fifth doctor's evidence is more "important" (in a human, not mathematical way) to me than the other four. He could have found something they all missed.

  Ahhh, the raven paradox. [0] It is a major problem for inductive logic. Too bad so few are aware of it. [0] https://en.wikipedia.org/wiki/Raven_paradox https://en.wikipedia.org/wiki/Raven_paradox

I actually thing the increasing reports are due to the situation improving in that there is more training and institutional support for complaints. More people are complaining about less egregious behavior because they're more sure that their voice will be heard.

So then we should have an article quantifying that with a fancy NYTimes data visualization, instead of just forming a perception based on what is truly just a handful of articles.
