  • I feel like this pattern of people lying to doctors and doctors adjusting things to account for it really messes with rigorously honest people.

    A little while back I was reading how when they ask you how much pain you’re in, with 10 being the most pain imaginable, they pretty routinely have people calmly say “12”. So, if you’re actually using the scale where you’ve probably never experienced more than a 9 and would be sobbing at an 8, so you say 7, they automatically assume you’re in basically no pain because you said less than 10.

    Kind of wish we could just speak accurately and take each other literally instead of playing games where we try to figure out exactly what lie to tell to convey the truth, but I guess that’s not how most people are wired.


  • Are you set on using light sources, or would you be okay with a shader that just creates the shadows without checking for specific light sources? It looks like this might do what you want, but you might need to modify it to work with your exact use case (multiple z levels).

    Generally it seems like some kind of shader might be your best option, it seems like the 2d lights are intended for casting lights within a given z level rather than between them. If you want more complex shadows across multiple z levels, you might need to create your own light objects (just a position, color, and intensity) and pass them to a shader that does something similar to the linked example, but modified based on your lights list.

    It’s possible there’s a simpler way that someone else could chime in with (I’m pretty new to godot), but as far as I can tell the built in 2d light and shadow systems aren’t designed for different z levels, so you’d need to use something else.




  • It means the overall death rate in the sample group was decreased substantially. The number of people who survived because they didn’t get lung cancer or blood clots was so large that it had a noticeable impact on the number of total survivors, even when you include death by bus. This is a useful measure for a couple of reasons. One, it accounts for the prevalence of the disease being prevented - cutting all pork from your diet prevents 100% of deaths by trichinosis, which accounts for like 0.00001% of deaths from all causes (completely made up numbers and example, without consulting any sources). Two, it could account for net change in survival, for a treatment or behavior that has both positive and negative effects - giving radiation therapy indiscriminately to everyone with any kind of lump might decrease rate of dying from breast cancer, but increase death “from all causes” because it causes more problems than it solves.

    I guess an additional way it might be useful is if we don’t yet have data on the exact mechanisms by which the treatment helps or what exactly its preventing - all we know is that we gave group A the treatment and not group B, and after 20 years there were a lot more people alive in group A, but we haven’t yet found a pattern in which causes of death were most affected and how.



  • This has been pretty widely discussed under the name “the double empathy problem”, although as always it’s good to have more actual data. The general gist in the existing discussion is that autistic people and allistic people have trouble with each other’s communication styles, but this is treated as a communication deficit in autistic people rather than two different styles that have difficulty understanding each other. An analogy might be a minority that (poorly) speaks the language of the majority, and then is considered stupid despite the fact that they are bilingual and none of the people they’re speaking to have made an effort to learn the minority language.

    I wasn’t sure to what extent this was autistic community in-group jargon, so I spent time trying to loosely explain it, when it turns out that a quick Google to check whether I’m crazy indicates it’s pretty well established and I could probably have just linked the Wikipedia page.

    For anyone else who was curious about lichens covering “a not insignificant amount” of the earth’s surface, a quick google tells me it’s about 7% (according to e.g. new york times, scientific american, etc)

    Edit: oh and estimating the age of an exposed surface by lichen diameter is called lichenometry. I’m seeing stuff about it being used in geological contexts but it makes sense that it could work for old buildings too

    Probably Wayne Gretzky? I don’t even know anything about ice hockey and I know he’s supposed to be the most dominant player of any sport. Like he and his brother have the record for highest combined goals of any pair of brothers: 2,857 by Wayne, 4 by Brent. If you take away all his goals, he’d be the highest scoring player of all time on assists alone. There have been 13 times when a player has scored over 100 goals in a season in NHL history: Lemieux (once), Orr (once), and Gretzy (eleven times in a row). He retired last century and still holds 57 records. I’m not gonna keep picking out examples but there’s a bunch more facts like this that sound like the old “chuck norris facts” meme but are actually true.

    “If you don’t know anything about ice hockey why do you have all these facts on hand?” - I remembered seeing this kind of list before so I did a quick Google.

    Edit: I’m seeing some different exact figures for some of these, but the general principle stands and I’m not invested enough in hockey facts to nail down which numbers are exactly right.
