This began at the Oklahoma bombing. I had a friend go. He came back so traumatized that he did not speak for years. People love to over generalize and rag on police officers and other first responders. There are more good cops than bad ones, some have witnessed some truly horrific scenes in the line of duty

Bored Panda reached out to Daniel T. Willingham, a professor of psychology at the University of Virginia and author, most recently, of Outsmart Your Brain: Why Learning is Hard and How You Can Make It Easy. He was kind enough to share some insights about why humans are so drawn to learning new facts and how we benefit from them.

According to the professor, one reason why we find facts interesting is that they are very context-specific. “For example, if I said ‘Would you like to know how guitars are made?’ you wouldn’t necessarily say ‘Yes!’ immediately. You’d more likely say ’Uh … maybe. Is it interesting?’”

ADVERTISEMENT

“What’s odd about facts is that the content matters less to whether or not you’d like to learn about it than you’d think,” he explained. Being a psychologist, Willingham is absolutely fascinated by human memory but sometimes it happens that when he goes “to professional meetings and attend talks about human memory that I find boring.”

“And then sometimes, I watch a documentary on something—for example, making guitars—that I didn’t think I’d find interesting in the least and find myself fascinated.”

That your brain erases your nose from your vision, until you actively think about it. You nose is obstructing your vision 100% of the time, but your brain interrupts it as useless information, and removes it. When you start thinking about it, or close one eye, you can see your nose again.

This might seem harmless until you realize the implications.

Your brain, without asking, erases something very real from your awareness. Imagine the possibilities of other things it's doing on it's own like that. There could be a literal 2nd world right in front of us, and it might just be being erased as useless information.

I had the honor of taking care of several people who had been in concentration camps(they had the tattooed numbers) and this is very true. One guy with dementia could only get baths, no showers because just the word shower sent him into a horrible memory sequence. Their stories were heartbreaking to say the least.

Curiosity is an innate drive we share with many other species, he told us. It prompts us to learn about our environment, which obviously helps individuals to survive: “We are not curious about everything—we are curious when we think a little exploration will lead to a lot of learning.”

Still, what we gain from learning new information depends on what we already know: “Suppose you say to me: ‘Would you like to know which, of all the bottled sauces made in Kenya, is the most popular?’ I can’t name even one … so if you tell me, that fact isn’t very informative.” 

“But suppose I knew a lot about African cuisine. Now that information would be informative, because I have some context to put it in, some existing knowledge to connect it to,” Daniel T. Willingham explained.

However, some say that taking the time and energy to learn interesting facts is a waste of time since this information is accessible with a few Google searches and quick clicks on the links. The professor disagrees, saying that factual knowledge is a really important driver of reading comprehension and other high-level thinking skills, like problem-solving.

“Think about how much easier it is to read a passage if you’re familiar with the general topic—I don’t care how ‘skilled’ a reader you are, if (like most Americans) you’re unfamiliar with the game of cricket, you will not be able to make sense of a newspaper account of the game,” Willingham elaborated.

People Are Sharing 35 Not Fun Facts They Wish They Didn't Know The image that most people have of blobfish is based on a misconception.

people think that’s what they look like all the time but blobfish adapted to live in deep waters, which means the deeper you go, the more water pressurethere is. Their bodies are not meaty like fish but more gelatinous because they adapted to the water pressure. if you accidentally pull them to higher levels but with less water pressure, their bodies don’t handle it well bc there’s nothing keeping their bodies in tact, so their bodies explode.

Basically, every photo you’ve seen of a blobfish where they look big and pink and, of course, blobby is a photo of a dead blobfish.

Merchandise and cartoons designed after what they look like dead. Hell, they’re referred to as what they look like dead.

Known as the "Ring of Death", it means that the turtle's eyesight has been permanently damaged due to mistaking your lights for the moon that guides it to the sea. By doing this, you have doomed the sea turtle to death right after birth.

Vasily Arkhipov was a Soviet navy officer who was the second in command of a B-59 submarine equipped with nuclear weapons at the height of the Cuban Missile Crisis. When the ships commander was told to launch the entire nuclear arsenal onboard, Arkhipov refused to authorize the attack, after realizing that the launch from the US was an error in their system.

If he wasnt on that submarine, the United States and Russia would be a big, grey spot on the globe.

This act lead to a lot of uncertainty on the part of the USSR - They simply did not know whether to execute him for insubordination or to give him a medal for saving the day. After thorough consideration they settled for the latter. He died of kidney cancer in 1998, probably as a late effect from radiation leaks on atomic submarines.

On September 26, 1983, at a nuclear bunker near Moscow, the computers reported a U.S. first strike was under way. Colonel Stanislav Petrov, on duty at the time, chose not to report the "attack" to the Kremlin, thus violating orders, as he believed it was a computer error. He was proven right. Had he blindly followed orders that day, most of the Northern Hemisphere would have become an irradiated wasteland.

Another close call. The authorities could neither publicly commend nor punish him, as that would have exposed the vulnerability of the rocket systems. So they just ignored the event, but a little while later - and of course completely without any ties to his role in this - Petrov was promoted and given a medal for his merits at "improving the facility".

That is very inaccurate. That “entire nuclear arsenal” consisted of exactly one nuclear torpedo, and launching the “special weapon” required the consensus of the three senior officers on board. The sub was out of radio contact because it was running deep to avoid detection. See: https://en.m.wikipedia.org/wiki/Soviet_submarine_B-59

You mixed something up. Arkhipov decided to go against the wishes of the other two commanders who held launch keys and were prepared to turn them, because he wanted to wait for clearer commands from the USSR government. There hadn't been a faulty US launch in that situation, however, the US launched explosives to force the USSR submarine to emerge. What you mean is Stanislav Petrov in 1983, as Rob Chapman described in the comments.

The reason you’re supposed to contact a doctor if you have an erection lasting longer than four hours is because prolonged priapism can lead to gangrene of the penis.

There is a mysterious illness called the 'sweating sickness' that hit in multiple small epidemics in the early modern era. It was incredibly contagious and massively deadly, with about a 50% average death rate, but it could be higher. It began with an ominous sense of apprehension, followed by severe pains in the neck and giddiness. They then abruptly stopped and switched to heavy sweating, headaches and delirium. Finally, the person was hit with an extreme urge to sleep, and it was thought to be fatal if you fell to it.

We know almost nothing about it, nothing about how it spread, how it was caused, only that if you got it you were either surviving or dead within 24hrs. There are horror stories of people leaving town on hunting trips and returning the same day to find almost everybody in the village dead, with only a few scattered survivors.

The worst thing was, you did not gain immunity. You could live through the sweating sickness once, and then get it a few days later and die. Or live through it two or three times, and then get it and die. It was horrific, and we don't know why it disappeared and we don't know if it will ever return.

The last outbreak occurred in 1551, after which the disease apparently vanished. It occurred near the time of The War of the Roses, speculation includes it was linked to the outrageous living conditions and bad sewage disposal or a hantavirus virus type of disease.
