That nobody would fund Christopher Columbus' voyage because they thought the world was flat. In 1492 people had known that the Earth was round for quite some time, and we actually had a very accurate estimate of how big it was. In fact there's some evidence that the reluctance to fund Columbus' voyage was because that most assumed you couldn't get to India by going west because, given the estimate of the Earth's size, there was probably a landmass in the way.

"NASA spent millions on developing a pen for space. The Russians used a pencil." [suggesting NASA isn't very intelligent] They were perfectly correct to make a pen for space. A pencil would have released loads of tiny graphite particles during use, which would float around and interfere with electronics.

I still hear that a lot of people believe the pyramids were built by slaves. They were not, they were paid workers. They even had benefits like bonuses and health care and the more skilled workers were allowed days off. (In ancient Egypt they had four categories that all careers fell into which are: manual work, administration, priesthood, military service.)

That Napoleon was short, he was of average height by those times. French just used the different scale of measurement.

That the Tiananmen Square massacre never happened. I studied in China and my teachers there gave me this watered-down, oversimplified story of what they were told as youngsters. You can't even find that section on Wikipedia when in China. Censorship is real.

Ok so, we have known for YEARS that Greco-Roman statues and buildings were painted rather than them being just plain white marble, but we actively ignored it.

So when people found old Greco-Roman statues they did notice staining from paint on some statues but ignored it because white marble was so beautiful and by the renaissance was pretty much a symbol of Rome and thus, civilization. Early art historians basically said "they were meant to be white because white bare marble was more beautiful" DESPITE EVIDENCE OF PAINT. When statues were found from Ancient Greece and Rome the remaining paint was washed off and even the Parthenon had obvious evidence of paint on it up until the 18th century. Even historical texts from the time talk about painted buildings and the discovery of Pompeii showed a Roman empire that was much more colorful than people wanted to admit.

So fast forward to the late 20th century when, after admitting amongst themselves that statues were likely painted announced to the world in a big way that yeah, the statues were painted. A Museum made a replica of Augustus of Prima Porta which they painted to the best evidence they had and the public hated it, with one art critic comparing it to a drag queen. Even when faced with the truth, people didn't merely reject it, they went against it. It got so bad that White nationalists sent death threats to art historians for stating that Greco-Roman statues were pained bright colors because it went against their image of ancient European civilization.

So yeah. Paleontologists might get flack for feathered Dinosaurs but at least they don't get death threats from White nationalists.

Almost anything involving the Library of Alexandria.

No, the Library of Alexandria was not the sole repository of knowledge in the ancient world. There were many other great libraries such as the one in Pergamum as well as many, many other collections.

No, we did not lose countless important works that could only be found there. The Library worked on copying works, and any important writings could easily be found in other libraries around the world.

No, we wouldn't be living in a utopia if it didn't burn because it was the centre of learning. The Library was in serious decline for almost a century before it burned. When Ptolemy VIII banned all foreign scholars from Alexandria, they moved to other libraries, and as Ptolemaic rule became less stable and the position of head librarian became a political position the prestige of the Library faded.

No, Julius Caesar did not burn it down on purpose. While he was besieged in Alexandria his troops set fire to some ships on the docks and the fire accidentally spread. However, it is unsure of how much of the Library was truly destroyed, as we know the Mouseion survived, and at any rate we know much was rebuilt later, with Mark Antony supposedly gifting some 200,000 scrolls to the Library, and Claudius built an additional to it during his reign.

No, the Christian Crusaders did not burn down the Library because they hated knowledge. First of all they didn't even attack Alexandria during the major Crusades (they would during a later minor one) besides they would be almost a 1000 years too late, as the last recorded evidence of the Library dates back to the middle of the 3rd Century, and any vestiges of the Library, which would have been a minor shell of its hight as Roman and Greek scholarship had long moved to other centres. At any rate what remained would have been destroyed during either Aurilian's attack of the city in 272 CE or Diocletian's in 297 CE.

That corsets were uncomfortable for women and they moved organs and made women faint. Women wore corsets for hundreds of years, they were the precursor to the bra. They were for support, they were not solidly boned, they were actually quite flexible. All women wore them, high ladies of society, working women, old women, young women. They can actually be quite comfortable. The myths that most people know stem from very high ladies of fashion. Corsetry and tight lacing are two different things. Most women did not have 18in waists. Just like today, the women that were placed in ads are skinny and unattainable. People were not shaped differently.

That the Roman Empire fell in 476 AD and then it was the dark ages. In reality, a peasant living through 476 probably wouldn't have realized they were living through the end of one age and the start of another. The beginnings of feudalism had already started back during Diocletian's reign, barbarians warbands and barbarian roman troops had been a fact of life for generations. The barbarian king who deposed Augustulus still considered himself a rightful representative of the Empire, etc. In some ways, the fall of Rome was sudden and traumatic (the population of Rome itself absolutely cratered in the 400's, after all), but it was really more of a gradual, centuries long transition than a fall.

That humanity happily left the struggles of hunting and gathering to gratefully pick up sedentary agriculture. Historical evidence suggests early states had to constantly round up farmers who decided that agriculture sucked and fled to be seminomadic or nomadic pastoralists and hunters. Thus early war's focus on taking slaves, which usually were resettled closer to state centers and integrated culturally. Agriculture was forced on most of humanity, not picked up as an improvement. Plenty of evidence also suggests that agriculture was much less energy efficient and ensured poor nutrition. Nomadic barbarians were often larger and healthier than antiquity farmers. Some anthropologists even think sedentary agriculture was a last ditch survival tool taken up during a climatological cataclysm and not seen as some technological progression by early humans. Neat stuff.

The Romans only briefly held Britain, they had occupied it longer than the USA has been a country.

That knights in plate mail were big, slow, clunky bruisers. In reality plate armor is actually easier to move around in than what we think of in video games as medium armor like chainmail. Why? Because its fitted to the wearer and held on with a complex collection of straps and belts. This distributes the weight evenly across the body. In comparison to chain mail (or samurai o-yoroi which often comes up when this is mentioned), this is far more comfortable as the others put weight straight on the arms and shoulders. In a similar vein, padded or cloth armor is often portrayed in games as the lowest form of protection but a properly made gamberson of such is actually surprisingly good protection. The layers of tough textile, often stitched so the weave is going in different directions each layer, actually can really stagger a slashing blow.

People believe, that the ex soviet union nations liked the soviet union and wanted to be annexed. the soviets treated the ex soviet countries badly. deportings every day. freedom of speech doesnt exist. you couldnt even show your countrys original flag.

The myth that Titanic was in any way badly designed, badly built, or badly operated - by the standards of the time. In fact there are so many crazy inaccuracies surrounding Titanic that it's hard to list them all here... But I'll give it a go!

She was an incredibly seaworthy ship - probably moreso than any passenger ship around today. The iceberg damage stretched almost a third of the way down her side, and she still stayed afloat for more than two hours!

In that time, all but two of her lifeboats were launched - there wasn't time to launch any more. She could have had a hundred more lifeboats on board, but that wouldn't have helped without vastly more crew to operate them.

Titanic's passengers genuinely did believe that she was practically unsinkable. When the time came to begin loading the lifeboats, many thought they would be safer staying on Titanic. There wasn't time for the crew to wait around convincing more people to get in, so when a lifeboat was ready, if there was no-one else waiting to get in, it had to go. This is why so many of Titanic's lifeboats left only half-full - it's not just because the crew were worried about over-filling them.

Titanic wasn't travelling too fast for the conditions - by the standards of practice around at the time. Further precautions were put into practice after the incident, but no-one on board can be blamed for doing what anyone on any ship would have done the same.

Titanic was by no means a fast ship, nor was she ever intended to be. The White Star Line (Titanic's owners) were in competition with one other big shipping line, Cunard. Cunard's liners (Mauretania, Lusitania and later Aquatania) were the fastest in the business. To combat this, instead of fighting for speed, White Star decided to try to make their liners the most luxurious in the world. Olympic and Titanic were famed for their splendour and comfort - passengers said that it was easy to forget that you were at sea, as there were very few vibrations from the engines, and the ships remained stable even in fairly rough seas. By comparison, Cunard's liners were very fast, but their quadruple-screw configuration made vibration more apparent. It's a myth that Titanic was ever trying to make record-breaking speed across the Atlantic.

She wasn't built using sub-standard materials. This rumour goes around a lot these days because of an article that was written some time ago; what the article is supposed to mean is that there is much better quality steel available today. This was not the case in 1909. Additionally, Titanic's builders were paid on a fee plus materials basis - they were given a set fee to construct the ship, plus the cost of all materials used. There was no incentive to use anything but the best steel they could get their hands on. The shipyard had an excellent reputation and would not risk tainting it by using bad steel, which could easily be noticed on inspection anyway.

Titanic and her two sister ships Olympic and Britannic were also surprisingly manoeuvrable for their size - much moreso than was expected. Some will tell you that Titanic's rudder was too small, but this simply isn't true. In fact, Olympic's wartime captain marvelled at her manoeuvrability, and was even able to throw her into a sudden turn, ramming (and sinking) a German U-boat. Olympic was the first of only two merchant vessels throughout the First World War recorded to have sunk an enemy vessel.

While it's true that the lookouts' binoculars were misplaced (or rather, locked away in a cabinet that no-one on board had the key to open), this made no difference to Titanic's fate. The images of sea captains and pirates scanning the horizon through telescopes, while common in films, has virtually no stead in reality. Binoculars and telescopes narrow your field of vision down to a fine point, making it harder to spot anything.

I was taught some 16-20 years ago that pretty much all slaves liked their owners, liked serving them, thought they got a good deal, etc. We were also told that "most of the ones that came here did so voluntarily"

That Anne Boleyn had six fingers. She would have never been a lady in waiting to Catherine of Aragon, or even a mistress to Henry if she did, as it would be considered an imperfection. Most of it was made up after she was executed.
