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

I have no words to describe that first big round whatever-it-is. Just the way they put percentages of income and percentages of people on the same scale would be enough to make this a terrible graph, but there's so much else going on that makes it one for the hall of fame.

They just really like circles.

I hope you don't make any maps! Just use the area. I agree that if you really want the difference magnitude to be easily and accurately perceived, you should be using bar lengths, but don't do some weird halfway thing.

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 got this title for the dumbest fucking possible take on sea shanties. Specifically, I derailed the meme thread because sailors in the 18th century weren't woke enough for me, and you shouldn't sing sea shanties. In fact, don't have any fun ever.
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.

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.

the dude's WAR is more than suspect: in his code he runs a simulation where if an average general has 99% of the air force/infantry/artillery/cavalry participating in a battle, he predicts that this guy would have a 75% chance of winning against another average general.

he's literally just adding wins and subtracting losses

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.

Well, it was only one of his many operations, most of which were successful, but...

Wikipedia posted:

Amputated the leg in under 2​1⁄2 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.

Well this was back in the early days, when being fast did indeed reduce mortality rates. Longer you had the patient open, especially in amputations, the more poo poo could go wrong.

Sometimes it backfired, though, as DACK informed us.

Mostly because modern anesthesia hadn't been invented yet, and the way to do surgery and kill the fewest patients was to do it as fast as possible before they bled out. 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.”

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.

It's often presented as such, when it comes up here, and on other sites, some of them more or less reputable news orgs, etc.

Edit: even when it's questioned it's usually in terms of "it might not have happened" rather than "it probably didn't." And I've never seen the claim that it was specifically made up to get back at him for suggesting doctors wash their hands.

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.

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.

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.

Does Science Advance One Funeral at a Time?

quote:

Knowledge accumulation — the process by which new research builds upon prior research — is central to scientific progress, but the way this process works is not well understood.

In Does Science Advance One Funeral at a Time? (NBER Working Paper No. 21788), Pierre Azoulay, Christian Fons-Rosen, and Joshua S. Graff Zivin explore the famous quip by physicist Max Planck. They show that the premature deaths of elite scientists affect the dynamics of scientific discovery. Following such deaths, scientists who were not collaborators with the deceased stars become more visible, and they advance novel ideas through increased publications within the field of the deceased star. These "emerging stars" are often scientists who were not previously active within that field. The results suggest that outsiders to a specific scientific field are reluctant to challenge a research star who is viewed as a leader within that field.
