They say, "you mean it's just sounds?" thinking that for something to just be a sound is to be useless, whereas I love sounds just as they are, and I have no need for them to be anything more than what they are.

Took me a while to work out that plane reply. Looks like a non-sequitur, but it's basically a diagram of where planes came back with bullet holes, so you armour the other spots because it means planes that got shot there didn't come back. So he's saying you've seen camouflage work a lot more, you just didn't notice, because it worked.

Doesn't this mean the armor worked, not the camouflage worked?

They’re saying people think of adding additional armor to the red-dotted areas

I think it's meant as an analogy. You didn't record the planes that got shot in the blank areas, because they didn't make it back for you to record that they got shot there -> You didn't notice the camouflage that worked, because it worked so well that you didn't see anything camouflaged was there at all

It's an analogy for survivorship bias. You didn't see the camoflauge, therefore there was no camoflauge.

The camouflage and the airplanes are both instances of Berkson's paradox, an incredibly general and counterintuitive phenomenon.

I uh... think the OP is saying the camo worked because its a white plane on a white background, and no critical areas were hit...

(Yes I know it's a pic for survivorship bias, but I still think that's :thejoke: the OP was trying to make.)

The plane picture is an image of where planes that made it back to base were being shot up. The initial interpretation was that this is where the planes should have their armour increased, because it's where they're getting shot. The actual, correct interpretation is that those planes were not shot anywhere that would be fatal, so you should up-armour the areas that were not shot. The ones that survived being what drives the dataset is called survivorship bias.

The same thing with camouflage . "This is the first time I've ever seen camouflage work" is something you say without realising you've seen it a thousand times, it just worked every time before now. So you don't include all the times that camouflage worked in the dataset you're using to base your assumptions on, meaning you're operating under an incorrect assumption that you've never seen it. It's basically the opposite of survivorship bias, because it's the ones that didn't make it that are driving your data.

The diagram is a very common demonstration of survivorship bias so it has become a minor meme to use in any instance where that is remotely applicable.

Allies in World War II (Let's just say Great Britain for simplicity) are trying to figure out the best place to armor their planes. They take the planes shot on missions that got back to Britain and analyze where the bullets most commonly hit. This is what the plane diagram is showing. So the obvious solution is to put thicker armor on the places that the bullets most commonly hit. However, someone points out that this is a logical fallacy. These are the planes that got back to Britain. It doesn't include the planes that were shot down in Germany and unable to be recovered. So it's actually a diagram showing where the bullets are less harmful, and the areas which don't have many bullet holes need to have thicker armor instead.

Back in the war people started noticing planes coming back with fairly specific patterns of damage and areas that weren't really hit at all. It took a bit for someone to figure out that you need to reinforce the bits that have no damage because the planes can fly fine when hit elsewhere but the ones hit in the 'undamaged' parts don't come back.

What they're saying by posting the image is that the fact that you're noticing the camo 'work' means it's not actually working. You never noticed the camo when it did work because it was doing its job.

It's survivorship bias.

Okay, so the plane picture. In WWII, the americans or english (can't remember which) did a study on their aricraft that returned from combat, to figure out where and how they got shot up. The result is the image above. The conclusion was, hey, this is where airplanes get hit, let's armour those places extra. Then some dude figured "No wait, this is where the airplanes that got back got hit." The planes that got hit in all the other places never even made it back to be studied. (Pretty obvious, when you think about it - there's for example very few hits recorded in the cockpit or engines on the surviving planes.)

Same idea behind the camouflage picture. Every camouflage that you've seen is by definition camouflage that isn't working.
