This is one of my favorites. I also enjoy the example of steel helmets in WW1. When steel helmets were first introduced in the British army there was a sudden massive spike in head wounds. They figured the helmets must be making the men too confident in exposing their heads, and they were nearly withdrawn from service. Fortunately a competent statistician was able to point out why there was a spike in head wounds. Before the helmets were introduced anyone who was hit in the head by a bit of artillery shrapnel would have been killed. With the helmets they were surviving to be listed as having head wounds.
@tempo5366 Жыл бұрын
I’m not sure about the British Army, but in the German Army both was true. People initially thought that the helmet was bulletproof, which made them stick out their head out of the trench and get shot. Same for the plane right? You don’t know if some parts of the plane are just less likely to get hit (for example the nose) or if those planes that get shot don’t come back. In reality it’s usually a combination of these factors.
@taylorminton1056 Жыл бұрын
Another massive change in wounds in military history is when units started getting issued field tourniquets. This is about from the 80s onward and particularly in the war on terror, where close explosions like IEDs go off all the time. Severe damage/loss of limb used to result in a lot more death than it does now. Rapidly used tourniquets from every single soldiers' IFAC meant that we were getting a lot more WIA soldiers with a limb gone, where before the massive blood loss from a lost limb usually ends up with a KIA.

Related to that is the study of ancient human remains. In cultures that developed agriculture, you see a general deterioration in the physical condition of the skeletons, with an increase in chronic health problems. Whereas among hunter-gatherer societies, the skeletons show individuals with higher average fitness. The obvious conclusion is that the agricultural lifestyle is not good for your health. But in fact, what it means is that those who would have been at a serious, even fatal, physical disadvantage in a hunter-gatherer society were more likely to survive and continue to be productive in an agricultural society.

@@wyattrichards7587 the funny thing is that's actually not how Newton's third law works at all. The action/reaction applies to forces, not energy. So even in the case of a gun where the recoil is caused by nothing else but the bullet, the bullet will actually have more energy than the recoil! That's because the same force is applied in both directions but, the bullet experiences the force over a longer distance i.e. approximately the length of the barrel. Work done on a particle is equal to force times distance, and work means the energy that is delivered to the particle. The gun on the other hand moves a smaller distance than the length of the barrel, so even if the force is the same the energy delivered to the gun by the recoil is smaller than the bullets energy. Your teacher did not only get the reality wrong, they also got the theory wrong. They ended up teachin people false physics.

Thats how teachers should be. He didnt call anyone by name or make them uncomfortable, force them to share opinions, or even make them stand up when they speak, making them most comfortable to engage in the discussion. Casually asks them to share their views if they have any, and remarks on their response then proceeds to take the lead. So informal yet absolutely effective. I wish I could be a teacher like him.

To simplify if anyone still lost.. You put armor on where there are no dots. The reason being: The planes who returned and gave this data, obviously survived DESPITE being shot at where the dots are. Those dots means you can get shot at those areas and still survive, planes who got shot at other spots did not survive to give the data.. Hence the bias. The dots represent strong points, empty spots represent weak points.

Tho, those planes were Doppeldecker planes and FAR from steong enough to carry armor, just about strong enough to carry a single bomb, a pilot and a light machinegun with a single belt of ammunition. So if you got hit in the engine, the pilot or one of the main support beams, you were right on f*cked. But there are pictures of planes being shredded by bullets and savely landing.

Another good example of how confusing statistics can be, most soldiers who had head injuries before helmets would inevitably perish making the number of “injuries” not actual injuries but deaths. By the time helmets became ubiquitous of course an injury to the head wouldn’t be nearly as severe, chances of survival were much higher. So head injuries rather than death were much more prevalent once helmets were implemented.

That's a slightly different problem from the survivorship bias.. It has to do with how you characterize / categorize data points. Practically, death is a subset of injury, and if you treat it like that in your statistics, injuries won't go up. However, if you've got one column named "injuries" and another column named "deaths" with no overlaps, you've got a flawed system and your injury rates will go up if you introduce measures that decrease the likelihood of you dying after suffering an injury.
@Ramsay584 жыл бұрын
When crash helmets were made compulsory in 1973, as well as neck injuries increasing, the rider death rate also increased - perhaps due to broken necks or people increasing their speed due to a false sense of security, but it's hard to be sure as it's said 88% riders already wore a helmet by choice. The same was not true when car seat belts were made compulsory in 1983 and car death rates immediately fell.

Had a grandfather who worked at an airbase during the war, helping coordinate bombing runs over various German cities. He never actually saw the impact the bombers had until the war ended, and a pilot offered to fly him over Germany. It was the first time he actually saw the destruction he'd helped create, and it haunted him for the rest of his life. It's one thing to see a demolished city in the middle of wartime, it's another to fly over it after the fighting's stopped, and just contemplate the impact your actions have had on the world.

Similar WWII story: there’s a famous book about how “deadly” it was to be in an American Sherman tank. The guy who wrote it was a tank-recovery specialist in the war. That means every single tank he encountered was a dead tank. What really happened was he only encountered tanks that were messed up and assumed every other tank was too. Furthermore: he compared decimated US tanks to disabled Nazi tanks, which is important because when Germans bailed from a tank, the US stopped shooting at it because the Germans were retreating and couldn’t go back to repair it. Germans meanwhile kept shooting dead US tanks so they couldn’t be repaired, because Americans were advancing and could retrieve dead tanks. For years people accepted it as gospel because they were viewing incomplete data

Also many more German tanks were destroyed by close air support than by tank on tank conflict. Advances in communication technology and tactics allowed ground personel to control air attacks.

@@shawnr771 Actually air power wasn't as effective on tanks as we think. Tests by the British showed that it took a fighter craft numerous passes to even hit a tank with an anti-tank rocket. And that was a stationary tank in the middle of an open field. In real combat the tank would evade and put machine gun fire near the fighter to make it worry about dodging. IIRC, according to the Chieftan, that the reason that aircraft is remembered at being effective against tanks is that when they found a tank and couldn't identify what killed it, aircraft was the default to record it as. Of course this doesn't mean that aircraft were useless against tanks. They were much more effective against the softer targets that make up the tank's supply line and a tank without fuel or ammo is useless. Also a tank focused on dodging an air attack isn't focused on enemy tanks or infantry with anti-tank weapons.

My favorite example of Survivor Bias has to do with the construction of buildings, in particular very old buildings from long in the past that survive to this day. Historians would study the methods used to construct these buildings and then assume that this was how all buildings were constructed in that particular era. The problem was, they were getting a very stilted representation of how buildings were built because the ones that survived were constructed extremely well with very high quality materials; whereas the vast majority of buildings were poorly constructed using inferior materials, which is why they no longer exist

People do this with many things when they say "they don't make'm like they used to." Yeah, your grandma's harvest gold fridge from 1962 that's still around is the one that just happened to survive this long while millions of others did not. People really need to learn about survivorship bias.

Which was perfectly obvious. I hate when people assume that there’s a massive Blindspot in every single industry that has anything even remotely related to a survivorship bias, and therefore everyone must be completely mentally and capable of understanding that the only 2000 year old structures that you see are going to be the well-built ones that survived 2000 years compared to the not well-built ones that didn’t survive 2000 years. Duh!

I remember once hearing it suggested that bias might actually affect average penis size. Basically, researchers weren't going out and measuring every penis they could get their hands on, but they were instead getting their data on a volunteer basis. So one could argue the males who volunteered to give their measurements were more likely to be on the bigger side because males with smaller penises would more likely be more embarrassed about participating. And then this becomes crazier when considering that the average being artificially inflated like this increases the likelihood of males being unconfident about their penis size. So yeah, there's a good chance that the average penis size is actually smaller than what's on record.

Another example can be found in World War 1. Soldiers were given bullet proof helmets and the amount of head injuries drastically increased! Do you know why? . . . What also happened is the amount of deaths from head injuries decreased. Soldiers that would have died from head injuries ended up coming back with head wounds instead.

I noticed that "volunteer bias" before I ever knew there was a name for it. Chuck out a random question on social media like "How many people here are left-handed", and you would think the number approaches 50% when really we lefties are the ones who are more likely to answer a question like that.

@goldeer71292 жыл бұрын
It' also extremely important here to say that they are NOT 50% of lefties but like 10~20%. If you only ask lefties to say they are, it's gonna be extremely biased since only a few right-handed will manifest. But, even if you ask "what is your dominant hand", left-handed people will answer more than actual average of left-handed people. Or, if you think the answer is obvious, that you're part of the majority of people, you may not answer. But if you are (or think you are) part of a minority of peope you probably will answer to be heard. This is one of the reasons taking surveys out of context can be dangerous and non-representative.

It's possible we can relate the discussion of bias to this comment section. If a lot of comments are related to his correct/incorrect retelling of history, does that say something about how people who like history react to potential falsifications? It's a compelling way to look at data. I would argue that comments on the internet are under constant competition due to the value and reward systems that the original creators of the systems put in place.
