90s Cringe Rock posted:People tend to be really awful at understanding and comparing the area of circles, though. That’s not the problem. The problem is the ambiguity; a circle’s diameter grows linearly with the radius while the area grows quadratically. Want to exaggerate a difference? Use the radius as scale. Want to diminish it? Use area. Both are bad because even if you state which you use, some people will intuitively misinterpret it, even if only subconsciously. It’s the same as when somebody presents a difference as a percentage: the absolute difference is probably infinitesimal (gene testing shows you are 20% more likely to get whichever rare cancer 5 people die from yearly) and if they use absolute numbers, it is an insignificant percentage (government spent $20M more on the poor). tl;dr: always use radius1.5 as scale for circles

Yeah this is a concept I've tried to explain to my family when they freak out about an ad on tv about food or lifestyle choices increasing their chances of getting whatever disease and it's impossible for some people to get that it's not "You now have a 20% chance of getting this" it's "your already super low chance just got bumped up a bit".

Just do a grid of whatever it is you're measuring. So, if you want to represent 100,000 people, do a grid of 10X10 little people icons, and have a thing at the bottom that says 1 icon = 1000 people Joke answer, do 316x316 icons

Were the few generals with -3 and -2 wars to their names peace activists or something? But they weren’t fighting too hard for peace either so it wouldn’t be considered its own kind of war for the purposes of this graph? E: Hold on, why is there enough space for 7 bars between 0 and 5 wars? I thought we were counting in whole numbers of wars, but apparently the correct reading is that more than 3000 generals have between 0 and 5/7 of a war to their names?

I was so baffled I read the article, and it's not wars, it's WAR - wins above replacement. How he calculates WAR is a bit suspect, but the biggest problem is that as far as I can tell it's an absolute sum of WAR stats, not an average, which means that someone with a long, successful, and above all famous campaign (like Napoleon or Julius Caesar) will have a huge numerical advantage vs. someone for whom only one battle is present on Wikipedia, even if they won that battle handily while at a huge disadvantage. Right after that graph he trash-talks Robert E Lee, so there's at least something good in the article.

It’s “wins above replacement”. It’s a coincidence that the acronym also means “major armed conflict”. Dividing it into bars of 0.7 units width is still whack.

Yes. “Wins above replacement” makes sense for sports teams where everyone is playing the same number of games, or if they aren’t, it’s a problem (like they’re out for injury). It makes a lot less sense for generals plucked from the last three millennia of warfare.

Among other things, I am fond of the insane way in which inconclusive battles, Pyrrhic victories, and victories in minor battles are not only counted as positive but are often more positive than decisive victories against superior forces.

Jurgan posted:Are you saying every time he attempted it, he killed the patient and two bystanders? Wikipedia posted:Amputated the leg in under 21⁄2 minutes (the patient died afterwards in the ward from hospital gangrene; they usually did in those pre-Listerian days). He amputated in addition the fingers of his young assistant (who died afterwards in the ward from hospital gangrene). He also slashed through the coat tails of a distinguished surgical spectator, who was so terrified that the knife had pierced his vitals he dropped dead from fright. That was the only operation in history with a 300 percent mortality.

After it was invented, he was a enthusiastic early adopter.

Too bad they didn’t have youtube at the time. I can imagine his speed run videos. “Ok, so here normally you’d have to cut diagonally along the hand of your assistant who’s holding the leg. But that’s the long way. If instead we cut straight through, it shaves nine frames off the animation, and it shortens the cut just enough that we’ll save an entire stitch later on. The best part is, cutting through the assistant’s fingers does not take any longer than cutting through the patient’s flesh only, so this maneuver is pure profit.”

Liston was a pioneer of surgery and did a generally good job of keeping people alive in an era where that was the exception rather than the rule.

The 300% mortality story and the accidentally took the patients balls off story are most likely gossip made by surgeons who were mad at him for daring suggest there might be less infections if they didn't spend all day covered in viscera. Primary sources usually agree he was crazy skilled and genuinely interested in improving the state of the art in technique and anesthetic.

A lot of people don't realize that it was only in the 19th century that we got rid of most of the insane medieval bullshit that was still in science (even if the foundations for modern science were laid in the 17th and 18th centuries). For example, the discussion about spontaneous generation wasn't fully put to rest until Pasteur's experiments. It's not that long ago.

groan I know I myself was glibly calling it medieval bullshit earlier, but with a lot of these major advances and discoveries they initially had no data or even cohesive theories to scientifically back them up. In many cases, the necessary framework or instruments just didn't exist yet. You can say people were slow to adopt them when the evidence did start piling up, but it's always easy to go 'lol idiots' in hindsight. We only know what's correct because that discussion happened and a new scientific consensus was eventually reached.

lol you think I'm wrong and doctors as a profession aren't REGULARLY like "im so smart i cannot be wrong" to this very day about things like "maybe the idea of studying only men because women are too complicated isn't actually correct"? never any issues related to patriarchy in this traditionally patriarchal profession that's groanworthy!

I don't think your observation of 'human pride exists' is wrong, just that it's not the only factor to explain why it took so long to adopt certain views that we now know to be correct. Continental drift is another example, you can think it's insane that it took so long for geologists to accept it, but without the explanatory mechanism of plate tectonics and a way to measure/prove that, it's just another theory.
