"My great great grandfather, a carpenter, did some work for a poor painter in the neighbourhood. The painter had no money, so he offered either a bottle of wine or a painting. My great great granfather chose the wine.

The painter was Edvard Munch, and the painting would have been worth millions upon millions today, or even just a few decades later (if translated to todays money)."

"Mao Zedong

Pest capaign: He basically told his nation to take pots and pans to kill all the sparrows. However, the ecosystem was disturbed and the locust population skyrocketed.

Seeds: he thought that planting seeds 1 meter in the ground would result in greater roots and better harvest. He also thought that putting tons of seeds in one compact area would cause a better harvest. All the seeds died however. Around 30 million or so died from Famine under his rule.

"Hey! Look at the other nations industrializing! Lets smelt all our metal to build better infrastructure. What? It creates pig iron which is super unstable and impure therefore being ultimately useless? Oops!" -Mao"

"Well, the decision of Inalchuq, the governor of the Khwarazmian city of Otrar, to attack Genghis Khan’s trade caravan was pretty bad. Khan was famous as a ruthless warlord, not the sort of guy you want to piss off.

But maybe they could have got away with it. Genghis sent three ambassadors to negotiate a settlement.

Which is when Muhammad II, the Shah of of Khwarzem, made the really bad decision to kill one of these ambassadors and send the other two back without their beards as a sign of humiliation.

Genghis Kahn was so enraged he assembled an army and destroyed the Khwarazmian Empire. Wiped out every town they had. He even re-routed a river to wipe out the village where the Shah was born, wiping it off the map. By 1120 there wasn’t much of anything left."

"Thomas Midgley Jr can lay claim to three:

First, he discovered and helped popularize the use of lead in petrol/gasoline, causing unimaginable harm to the atmosphere and our brains. He contracted lead poisoning when working on the project, but apparently neglected to draw any conclusions from this.

Second, he lead the team that discovered freon, the first chlorofluorocarbon, and helped popularize the use of CFCs in refrigeration and industrial applications, causing further unimaginable harm to the atmosphere

It’s suggested that he had a greater impact on the atmosphere than any other single person in history.

As for the third, well:

In 1940, at the age of 51, Midgley contracted poliomyelitis, which left him severely disabled. He devised an elaborate system of ropes and pulleys to lift himself out of bed. In 1944, he became entangled in the device and died of strangulation."

"Maybe the worst business decision ever made was by Xerox with their Alto computer.

Xerox invented the graphical interface modern computers use. Desktop, folders, copy/paste etc. They basically invented the modern computer in the '70s. But the problem was, the people in charge at the time were businessman without any technical knowledge so they didn't realize what they had. They did nothing with it and gave it away to universities and showed other companies. The famous story is that Steve Jobs saw this and within 5 minutes realized this was the way computers would work in the future. He copied it, because Xerox didn't patent their invention and didn't do anything with it and the rest is history."

"Two terrible decisions for the price of one:

The British gave Native American's blankets diseased with smallpox to "thin" out their ranks during The French and Indian War. They didn't anticipate just how deadly this would be; some tribes losing as much as 90% of their number due to the epidemic.

When Edward Jenner invented the smallpox vaccine, Britain made fast allies by exporting it out to the world. Some of those shipments were to be sent to the United States, with the intention of helping both the Colonial American populace and the Native American Populace.

Only problem was that the Colonials and the Natives were having a bit of a war for the west at the time. The US Army took the vaccines hostage, with the intention of letting more Natives die, until they gave up and moved into the reservations the US Army had built for them.

Native Americans just can't catch a break at all."

"Robert Ballard, one of the guys who discovered Titanic, says that his biggest regret is that he and Jean-Lous Michel didn’t bring a piece of the Titanic up with him when he first discovered it in 1985. At the time, they didn’t want to disturb the wreck, and leave it pristine. But if they had done so, then they would’ve been able to claim legal ownership of the wreck under international maritime law, and therefore more control over it. Because they chose not to do that, everyone and their grandma is free to take artifacts and pieces of the wreck, and this makes preservation impossible."

"How about the greatest single decision that could have ended up as the worst single decision in history ever made by a person?

Vasily Arkhipov. The man who was solely responsible for preventing nuclear war in 1962. The three officers on board the diesel-powered and nuclear armed B-59 sub had to agree unanimously to launch the nuclear torpedo. Conditions due to the Kennedy administration's blockade began to take a toll upon the crew members. Diesel subs can get incredibly hot over extended periods of time, the batteries failed and the air conditioning stopped, and the lack of fresh air from increased carbon dioxide levels means delirious crew members. Eventually two officers, Captain Savitsky, and the political officer Ivan Semonovich Maslennikov got sick of waiting due to thinking WWIII had already begun and decided to go through with the launch. But Arkhipov was second in command and his position as flotilla commander meant they also needed his approval to launch it. If he wasn't a flotilla commander it wouldn't have been needed gain his approval even as second in command. Vasily disagreed and all three actually got into a physical confrontation, fighting over command of the torpedo. Eventually they agreed with Vasily and had brought the sub to surface. Needless to say, they faced criticism and were disgraceful to their superiors who would have rather saw them go down with their ship than be captured by the enemy.

According to Wikipedia: ''Each captain was required to present a report of events during the mission to the Soviet defense minister, Andrei Grechko. Grechko was infuriated with the crew's failure to follow the strict orders of secrecy after finding out they had been discovered by the Americans. One officer even noted Grechko's reaction, stating "upon learning that it was the diesel submarines that went to Cuba, removed his glasses and hit them against the table in fury, breaking them into small pieces and abruptly leaving the room after that."

It's safe to say that there's an almost unanimous amount of agreement over the importance of Arkhipov's decision. Everyone from Chomsky, to McNamara have agreed that this was the defining moment of whether or not we would prevail as a species. This was it. The test. The launch of the torpedo would have meant the nuclear destruction of the blockade above, and thus the invasion of Cuba and the launching of the NATO nukes in Turkey and other European countries. Meaning the missiles in Cuba which were operational at this point, would have decimated all the major cities on the Eastern seaboard, and the major cities in the Midwest.

Arthur M. Schlesinger Jr., an advisor for the John F. Kennedy administration and a historian, has stated, "This was not only the most dangerous moment of the Cold War. It was the most dangerous moment in human history."

"Brutus decided to join Cassius in murdering the dictatorial tyrant, Caesar. The reason? They suspected his intent to become a king.

Which then started a chain of events leading to his adopted son Caesar becoming a military dictator without equal, having all the powers of a king without being called one.

When this Caesar Augustus dies, his name and title is passed on for the next four hundred years almost like you would a crown. Monarchies then returned all over Europe, in the style of Augustus Caesar.

And so, the decision of Brutus to join the conspiracy in effect changed all of Western civilization for the next 1900 years to adopt the very political style he wanted to avoid.

It would not be until the 1770s when America and later France would begin revolting and experimenting with Democracies and Republics."

"William Howard Taft running for US president:

Prior to ww1, the US elections took place with Woodrow Wilson winning with a 36% (give or take) majority, how could this happen? Taft. The election was split 3 ways, Wilson for the democrats, and Taft and Teddy Roosevelt for the Republicans, they split the vote and Wilson Won. Had Taft not split the vote Roosevelt would have won and serve a third presidential term. As president, Roosevelt would have almost definitely pushed the US one WW1 much earlier than Wilson did, possibly shortening the war by up to a year. The main impact of this would have been on Russia, while it wouldn’t have saved the Tsar, it would have put down Lenin and prevented the rise of Communism, as it would have denied Lenin the public backing he needed, given that the current govt. didn’t look quite so incompetent. With no Lenin, no Stalin, no mass genocides, speaking of genocides, the fear of communist take-over largely fuelled support for the Nazi party and without them, Hitler would have lived and died a fringe extremist with very few people even noticing him.

TLDR; Taft ran for president, split the vote, denied Roosevelt a third term, which lead to a prolonged WW1, the Russian Communist take over, WW2, Cold War, etc."

"Here’s a recent one...

After successfully invading Iraq and toppling Saddam Hussein, the US decided that all members of the ruling Baath party should be banned from government and military positions in the new government.

The result was a crop of knowledgeable bureaucrats and military leaders available to join a group of terrorists under Zarqawi to form a little group that would go on to become ISIS."

"John H. Sununu might count. He was an MIT educated engineer, brilliant guy, PhD in mechanical engineering. He even served on MIT's Advisory Board of the Technology and Policy. He remains a member of the National Academy of Engineering. More importantly, he was a governor of NH and later the White House Chief of Staff under George H.W. Bush.

As Bush's adviser, he was the first one with a STEM background to doubt climate change. He publicly questioned the validity of James Hansen / NASA's modeling efforts. In fact, the US was on the verge of signing a binding climate treaty with 65 other nations (in 1989!)

Prior to this point, the argument was "how do we balance emission reductions versus economic losses", with conservative forces recognizing the danger but insisting we protect businesses from overreaching regulation. After Sununu's public doubts, the entire debate shifted to "is climate change even real?". It inspired the "everything's fine" PR campaign that has been ongoing ever since. I honestly suspect treaty opponents didn't even realize that pure denial would be a realistic strategy until Sununu called James Hansen a liar.

I guess in another 50 years we'll see the true extent of the damage he did. Ironically all this falls not on some moron, but on a brilliant guy who decided to speak on something outside his expertise."
