Some people swear by things they picked up at school or university, others rely on the opinions of experts, while there are also some who get their intake of facts from the World Wide Web. And while some of the sources might seem more reliable than others, it's not uncommon that all of them might be incorrect sometimes.

There are plenty of scientific theories that have been proven wrong, so things that you've heard from 3 friends and aunt and your grandma can definitely be wrong. Here's a list of half-truths and all-lies that many people believe but actually have either been disputed or don't have any actual substance to them, according to Wikipedia. Scroll down, read through, and see if your own perception of truth and reality is challenged. Oh, and don't forget to comment and vote on your favorites!

A Common Belief Regarding Self-Harm Is That It Is An Attention-Seeking Behaviour; In Many Cases, This Is Inaccurate

Many self-harmers are very self-conscious of their wounds and scars and feel guilty about their behaviour, leading them to go to great lengths to conceal their behaviour from others. They may offer alternative explanations for their injuries, or conceal their scars with clothing.

There Is No Such Thing As An "Alpha" In A Wolf Pack

There Is No Such Thing As An "Alpha" In A Wolf Pack

An early study that coined the term "alpha wolf" had only observed unrelated adult wolves living in captivity. In the wild, wolf packs operate more like human families: there is no defined sense of rank, parents are in charge until the young grow up and start their own families, younger wolves do not overthrow an "alpha" to become the new leader, and social dominance fights are situational.

Humans Have More Than The Commonly Cited Five Senses

Humans Have More Than The Commonly Cited Five Senses

The number of senses in various categorizations ranges from five to more than 20. In addition to sight, smell, taste, touch, and hearing, which were the senses identified by Aristotle, humans can sense balance and acceleration (equilibrioception), pain (nociception), body and limb position (proprioception or kinesthetic sense), and relative temperature (thermoception). Other senses sometimes identified are the sense of time, echolocation, itching, pressure, hunger, thirst, fullness of the stomach, need to urinate, need to defecate, and blood carbon dioxide (CO2) levels.

Napoleon Bonaparte Was Not Short

Napoleon Bonaparte Was Not Short

He was actually slightly taller than the average Frenchman of his time. After his death in 1821, the French emperor's height was recorded as 5 feet 2 inches in French feet, which in English measurements is 5 feet 7 inches (1.70 m). He was actually nicknamed le Petit Caporal (The Little Corporal) as a term of endearment. Napoleon was often accompanied by his imperial guard, who were selected for their height—this could have contributed to a perception that he was comparatively short.

The Forbidden Fruit Is Not Apple

The Forbidden Fruit Is Not Apple

The forbidden fruit mentioned in the Book of Genesis is never identified as an apple, a misconception widely depicted in Western art. The original Hebrew texts mention only tree and fruit. Early Latin translations use the word mali, which can be taken to mean both "evil" and "apple". In early Germanic languages the word "apple" and its cognates usually meant simply "fruit". German and French artists commonly depict the fruit as an apple from the 12th century onwards, and John Milton's Areopagitica from 1644 explicitly mentions the fruit as an apple. Jewish scholars have suggested that the fruit could have been a grape, a fig, wheat, an apricot, or an etrog.

Albert Einstein Did Not Fail Mathematics Classes

Albert Einstein did not fail mathematics classes (never "flunked a math exam") in school. Upon seeing a column making this claim, Einstein said "I never failed in mathematics... Before I was fifteen I had mastered differential and integral calculus." Einstein did, however, fail his first entrance exam into the Swiss Federal Polytechnic School (ETH) in 1895, when he was two years younger than his fellow students, but scored exceedingly well in the mathematics and science sections, then passed on his second attempt.

Leif Erikson, and possibly other Vikings before him, explored Vinland, which was either the island of Newfoundland, part of modern Canada, or a term for Newfoundland and parts of the North American mainland. Ruins at L'Anse aux Meadows prove that at least one Norse settlement was built in Newfoundland, confirming a narrative in the Saga of Erik the Red. Columbus also never reached any land that now forms part of the mainland United States of America; most of the landings Columbus made on his four voyages, including the initial October 12, 1492 landing (the anniversary of which forms the basis of Columbus Day), were on Caribbean islands that are now independent countries.

Pencils cannot be used in space because the graphite dust and particles they generate pose fire, puncture and inhalation hazards in a low-gravity, high-oxygen environment, something even the Soviets acknowledged. The space pen was independently developed by Paul C. Fisher, founder of the Fisher Pen Company, with $1 million of his own funds. NASA tested and approved the pen for space use, then purchased 400 pens at $6 per pen. The Soviet Union subsequently also purchased the space pen for its Soyuz space flights.

Shaving Does Not Cause Terminal Hair To Grow Back Thicker (More Dense) Or Darker

This belief is due to hair that has never been cut having a tapered end, whereas after cutting the edge is blunt and therefore thicker than the tapered ends; the cut hair appears to be thicker and feels coarser due to the sharper, unworn edges. The shorter hairs being less flexible than longer hairs also contributes to this effect.

There Is No Evidence That Jesus Was Born On December 25

The Bible never claims a date of December 25 (he and his followers primarily used the Hebrew calendar, which as a lunisolar calendar does not have a day-to-day correspondence to the fully solar Roman calendar nor its modern-day descendant Gregorian calendar); contextual clues may imply a date in or around September. The fixed date is attributed to Pope Julius the First because in the year 350 AD he declared the twenty-fifth of December the official date of celebration. The date may have initially been chosen to correspond with either the day exactly nine months after Christians believe Jesus to have been conceived, the date of the Roman winter solstice, or one of various ancient winter festivals.

Great White Sharks Do Not Mistake Human Divers For Pinnipeds

Their attack behaviors on humans and pinnipeds are very different: when attacking a seal, a great white shark surfaces quickly and violently attacks it. Attacks on humans, on the other hand, are more relaxed and slow: the shark charges at a normal pace, bites, and swims off. Great white sharks have efficient eyesight and color vision; the bite is not predatory, but rather for identification of an unfamiliar object.

Mental Abilities Are Not Absolutely Separated Into The Left And Right Cerebral Hemispheres Of The Brain

Mental Abilities Are Not Absolutely Separated Into The Left And Right Cerebral Hemispheres Of The Brain

Some mental functions, such as speech and language (such as Broca's area and Wernicke's area), tend to activate one hemisphere of the brain more than the other in some kinds of tasks. If one hemisphere is damaged or removed at an early age, these functions can often be recovered in part, or even in full, by the other hemisphere (see neuroplasticity). Other abilities, such as motor control, memory, and general reasoning, are served equally by the two hemispheres.

Most Diamonds Are Not Formed From Highly Compressed Coal

Most Diamonds Are Not Formed From Highly Compressed Coal

More than 99 percent of diamonds ever mined have formed in the conditions of extreme heat and pressure about 140 kilometres (87 mi) below the earth's surface. Coal is formed from prehistoric plants buried much closer to the surface, and is unlikely to migrate below 3.2 kilometres (2.0 mi) through common geological processes. Most diamonds that have been dated are older than the first land plants, and are therefore older than coal. It is possible that diamonds can form from coal in subduction zones and in meteoroid impacts, but diamonds formed in this way are rare and the carbon source is more likely carbonate rocks and organic carbon in sediments, rather than coal.

The Flight Mechanism And Aerodynamics Of The Bumblebee (As Well As Other Insects) Are Actually Quite Well Understood

Despite the urban legend that calculations show that they should not be able to fly, the flight mechanism and aerodynamics of the bumblebee (as well as other insects) are actually quite well understood. In the 1930s, the French entomologist Antoine Magnan indeed postulated that bumblebees theoretically should not be able to fly in his book Le Vol des Insectes (The Flight of Insects). Magnan later realized his error and retracted the suggestion. However, the hypothesis became generalized to the false notion that "scientists think that bumblebees should not be able to fly".

It is a question of simplifying. If do the simple maths on bumblebees, the result is that they can not flap their wings fast enough (muscle speed and strength, nerve firing rate, speed of neural signals and such). When you start to factor in variables like the hydrostatic rebound of the thorax, reflex motion of other muscles, suddenly they can fly. Of course the old joke is never to tell the bumblebee it can't fly.

Bats Are Not Blind

Bats Are Not Blind

While about 70 percent of bat species, mainly in the microbat family, use echolocation to navigate, all bat species have eyes and are capable of sight. In addition, almost all bats in the megabat or fruit bat family cannot echolocate and have excellent night vision.

The Word Theory In "The Theory Of Evolution" Does Not Imply Scientific Doubt Regarding Its Validity

The Word Theory In "The Theory Of Evolution" Does Not Imply Scientific Doubt Regarding Its Validity

The concepts of theory and hypothesis have specific meanings in a scientific context. While theory in colloquial usage may denote a hunch or conjecture, a scientific theory is a set of principles that explains observable phenomena in natural terms. "Scientific fact and theory are not categorically separable", and evolution is a theory in the same sense as germ theory or the theory of gravitation.

Exactly I wish this concept was more wide spread. Since many people usually dismiss evolution as a "theory" and use the colloquial usage to try to denounce it.

Waking Sleepwalkers Does Not Harm Them

Waking Sleepwalkers Does Not Harm Them

While it is true that a person may be confused or disoriented for a short time after awakening, this does not cause them further harm. In contrast, sleepwalkers may injure themselves if they trip over objects or lose their balance while sleepwalking.

I once had a nightmare that my friend was sleepwalking into her suicide through a wide open window. I stopped her and that woke her up and she looked confused indeed. I woke up from that dream with deep thoughts.

The Order In Which Different Types Of Alcoholic Beverages Are Consumed Does Not Affect Intoxication Or Create Adverse Side Effects

The Order In Which Different Types Of Alcoholic Beverages Are Consumed Does Not Affect Intoxication Or Create Adverse Side Effects

The order in which different types of alcoholic beverages are consumed ("Grape or grain but never the twain" and "Beer before wine and you'll feel fine; wine before beer and you'll feel queer") does not affect intoxication or create adverse side effects.

Twinkies Have A Shelf Life Of Approximately 45 Days (25 In Their Original Formulation)

Twinkies Have A Shelf Life Of Approximately 45 Days (25 In Their Original Formulation)

It's far shorter than the common (and somewhat jocular) myth that Twinkies are edible for decades or longer. They generally remain on a store shelf for only 7 to 10 days

Black Holes Have The Same Gravitational Effects As Any Other Equal Mass In Their Place

Black Holes Have The Same Gravitational Effects As Any Other Equal Mass In Their Place

They will draw objects nearby towards them, just as any other planetary body does, except at very close distances to the black hole. If, for example, the Sun were replaced by a black hole of equal mass, the orbits of the planets would be essentially unaffected. A black hole can act like a "cosmic vacuum cleaner" and pull a substantial inflow of matter, but only if the star from which it formed was already having a similar effect on surrounding matter.

Marie Antoinette Did Not Say "Let Them Eat Cake" When She Heard That The French Peasantry Were Starving Due To A Shortage Of Bread

Marie Antoinette Did Not Say "Let Them Eat Cake" When She Heard That The French Peasantry Were Starving Due To A Shortage Of Bread

The phrase was first published in Rousseau's Confessions when Marie was only nine years old and most scholars believe that Rousseau coined it himself, or that it was said by Maria-Theresa, the wife of Louis XIV. Even Rousseau (or Maria-Theresa) did not use the exact words but actually Qu'ils mangent de la brioche, "Let them eat brioche" (a rich type of bread). Marie Antoinette was an unpopular ruler; therefore, people attribute the phrase "let them eat cake" to her, in keeping with her reputation as being hard-hearted and disconnected from her subjects.

Toilet Waste Is Never Intentionally Jettisoned From An Aircraft

Toilet Waste Is Never Intentionally Jettisoned From An Aircraft

All waste is collected in tanks and emptied into toilet waste vehicles. Blue ice is caused by accidental leakage from the waste tank. Passenger trains, on the other hand, have indeed historically flushed onto the tracks; modern trains usually have retention tanks on board and therefore do not dispose of waste in such a manner.

Nonstandard, Slang Or Colloquial Terms Used By English Speakers Are Sometimes Alleged Not To Be Real Words, Despite Appearing In Numerous Dictionaries

Nonstandard, Slang Or Colloquial Terms Used By English Speakers Are Sometimes Alleged Not To Be Real Words, Despite Appearing In Numerous Dictionaries

All words in English became accepted by being commonly used for a certain period of time; thus, there are many vernacular words currently not accepted as part of the standard language, or regarded as infelicitous in formal speech or writing, but the idea that they are somehow not words is a misconception. Examples of words that are sometimes alleged not to be words include "irregardless", "conversate", "funnest", "mentee", "impactful", and "thusly", all of which appear in numerous dictionaries as English words.

Alcohol Does Not Necessarily Kill Brain Cells

Alcohol Does Not Necessarily Kill Brain Cells

Alcohol can, however, lead indirectly to the death of brain cells in two ways: (1) In chronic, heavy alcohol users whose brains have adapted to the effects of alcohol, abrupt cessation following heavy use can cause excitotoxicity leading to cellular death in multiple areas of the brain. (2) In alcoholics who get most of their daily calories from alcohol, a deficiency of thiamine can produce Korsakoff's syndrome, which is associated with serious brain damage.

In South Korea, It Is Commonly, And Incorrectly, Believed That Sleeping In A Closed Room With An Electric Fan Running Results In "Fan Death"

In South Korea, It Is Commonly, And Incorrectly, Believed That Sleeping In A Closed Room With An Electric Fan Running Results In "Fan Death"

According to the Korean government: "In some cases, a fan turned on too long can cause death from suffocation, hypothermia, or fire from overheating." The Korea Consumer Protection Board issued a consumer safety alert recommending that electric fans be set on timers, the direction changed, and any doors to the room be left open. According to Yeon Dong-su, dean of Kwandong University's medical school, "If it is completely sealed, then in the current of an electric fan, the temperature can drop low enough to cause a person to die of hypothermia." However, leaving a fan running in an unoccupied room will not cool it down; rather, due to energy losses from the motor and viscous dissipation, a fan will actually slightly heat a room

Houseflies Have An Average Lifespan Of 20 To 30 Days, Not 24 Hours

The misconception may arise from confusion with mayflies, which, in some species, have an adult lifespan of as little as 5 minutes. A housefly egg will hatch into a maggot within 24 hours of being laid.

When Kitty Genovese Was Murdered, 37 Neighbors Did Not Stand Idly By And Watch, Not Calling The Police Until After She Was Dead

When Kitty Genovese Was Murdered, 37 Neighbors Did Not Stand Idly By And Watch, Not Calling The Police Until After She Was Dead

When bartender Kitty Genovese was murdered outside her Queens apartment in 1964, 37 neighbors did not stand idly by and watch, not calling the police until after she was dead, as The New York Times initially reported to widespread public outrage that persisted for years. Later reporting established that the police report the Times had initially relied on was inaccurate, that Genovese had been attacked twice in different locations, and while the many witnesses heard the attack they only heard brief portions and did not realize what was occurring, with only six or seven actually reporting seeing anything. Some called police; one said "I didn't want to get involved", an attitude later attributed to all the residents who saw or heard part of the attack.
