8 Brain 'Facts' We All Get Wrong

Are you left-brained or right-brained? The correct answer is “neither.” Read on to find out the science behind this and seven other brain “facts” we all get wrong.

1. A BIGGER BRAIN IS A BETTER BRAIN.

Nope. After all, humans believe we’re the smartest animals on the planet, but elephant brains are three times larger than ours. And whale brains? Forget it. 

Intelligence isn’t about relative size, either. Human brains make up about 2 percent of our body mass, which is pretty impressive. But tree shrew brains are a full 10 percent of their body mass, and they drink beer for a living.

So when it comes to brains, size isn't the most important thing. Hominid brain size did increase as we evolved, but scientists say that the secret to our smarts is complexity. And nobody can beat us there; neuroscientist Gerard Edelman has even described the human brain as “the most complicated object in the universe.” Your cerebral cortex alone has between 19 and 23 billion neurons, and each neuron can connect to other neurons tens of thousands of times. 

2. PEOPLE ARE EITHER LEFT-BRAINED OR RIGHT-BRAINED.

There are certain tasks that draw more on one side of your brain than the other, but everything you do uses both hemispheres. There’s no evidence that the right half of your brain is more creative, or that the left is more analytical. The myth originated in the 1970s, from a paper by CalTech neuroscientist Roger W. Sperry. Sperry reported finding cognitive differences between the hemispheres. The media took the idea and ran with it. Sperry warned against oversimplifying or misinterpreting his findings, but by then the proverbial horse was out of the barn. 

The only people who are truly left- or right-brained are those who have undergone hemispherectomies—a surgery in which half of the brain is removed. The procedure is more common than you might think, and patients often go on to live full lives with no cognitive troubles. We'll have a story about this procedure and the impact it had on the life of one remarkable young woman later this week. 

3. WE ONLY USE 10 PERCENT OF OUR BRAINS.

Oh yeah? Which part are you using right now? The entire brain may not be active every second of every day, but if you want to breathe, sleep, and digest your food, you need the whole thing. 

Modern brain imaging techniques have given us actual pictures of the whole brain in action, which should have put this myth to bed. Instead, the 10 percent legend has persisted for years and years, in part thanks to movies and psychics who argue that the “other 90 percent" of your brain must be reserved for some supernatural purpose. This is absolute bunk. We'll look at this myth in more detail later in the week too.

4. GETTING OLDER MEANS LOSING YOUR MENTAL EDGE.

It’s not that black and white. Yes, certain cognitive functions like short-term memory, attention, and language learning begin to decline with age, but other mental skills actually improve. Many of these are social and emotional in nature, rather than analytical. This may be why these gains haven’t gotten as much attention as the losses: Laboratory tests focus more on cerebral tasks than on practical mental skills. 

Studies have shown that older people have larger vocabularies than younger people, and that they make better use of them. Older adults are happier with their lives, and their relationships are more harmonious. Being older means that you have access to a mental database of past problems and solutions, which helps you make choices in the present. Scientists call this a “cognitive template,” but most of us know it better as wisdom.

5. CLASSICAL MUSIC MAKES YOU SMARTER.

Making yourself (or your baby) sit through symphonies won’t do anything for your IQ. A 1993 study [PDF] did show that listening to Mozart improved spatial reasoning—but only spatial reasoning, and only for 15 minutes. Even that modest effect might have been overstated. A 2010 review of 40 studies on the subject found that none of them could reproduce the results of the original experiment.

And those classical music videos for babies aren’t doing anybody any favors. Infants and toddlers who watch TV—even Baby Mozart—learn fewer words than their peers.

Classical music is not like broccoli. You can’t put cheese on it, and the only reason to consume it is if you (or your baby) actually like it.

6. CROSSWORD PUZZLES WILL KEEP YOU SHARP.

Like classical music, crossword and Sudoku puzzles are terrific—but only if you actually enjoy them. 

In an interview on the subject with The New York Times, neuroscientist Molly Wagster of the National Institute on Aging was unequivocal: “People who have done puzzles all their lives have no particular cognitive advantage over anyone else.” 

There is one thing that doing crossword puzzles will make you good at: doing crossword puzzles. The more puzzles you complete, the better equipped you’ll be to notice patterns and recognize frequently used clues.

7. MEN ARE NATURALLY BETTER THAN WOMEN AT MATH.

Just like women are naturally better at washing the dishes, right? No. Come on.

Study after study [PDF] has shown that the gap in math and science test scores between girls and boys can be attributed not to natural ability, but to cultural messages. It’s called the stereotype threat: When a member of a group is exposed to negative stereotypes about that group, they perform poorly. Just requiring girls to check “female” before beginning a standardized test has been shown to significantly reduce their scores. The more a person is bombarded with expectations of failure, the more likely it is that he or she will fail.

Researchers from the University of Wisconsin analyzed test scores [PDF] from 86 countries and found that average math scores for girls and boys were equal. Even in the United States, the gap has begun to narrow. 

"We have to stop selling T-shirts to girls that say, ‘I'm too pretty to do math,'” study co-author Jonathan Kane told CNN. "Our stereotypes are hurting our math education.”

8. YOUR BRAIN CAN'T CHANGE OR HEAL.

The brain you have now is the brain you’ve always had and always will … right? Wrong.

The human brain is astonishingly plastic and can adapt to all kinds of extreme situations. People who lose their sight find that their sense of hearing improves dramatically, because the brain dedicates more energy to auditory processing. And, as we’ve seen, people who’ve had half their brain removed can still function, because the remaining half takes up all the responsibilities. Our brains are not hard-wired in any sense of the word.

Our brains are also not a finite resource. Cells in the rest of our bodies are constantly dying and being replaced. For a long time, scientists believed that the brain was the exception to this rule, and that damaged brain cells would never grow back. We now know this isn’t the case.

20 John Carpenter Quotes About Horror Movies
Amy Sussman/Getty Images for Tribeca Film Festival
Amy Sussman/Getty Images for Tribeca Film Festival

Though he’s made a variety of movies—from fantasy to science fiction films—John Carpenter will forever be known as a master of horror, thanks in large part to the role he played in reinventing the genre with 1978’s Halloween. To celebrate the award-winning filmmaker’s 70th birthday, we’ve gathered up 20 of his most memorable quotes about Hollywood.

1. ON THE DEFINITION OF HORROR

“Horror is a reaction; it's not a genre.”

—From a 2015 interview with Interview Magazine

2. ON THE RULES OF MOVIEMAKING

“I think the rules of filmmaking are essentially the same as they were since, I guess, The Birth Of A Nation. The way you make movies: long shot, close-up, camera movement, structure—it’s all the same. Not much has changed. But the technology of movies has vastly changed. From 35mm black-and-white to color, from nitrate film to safety film and now into digital—and yet we’re still breaking scenes into master shots and close-ups. The cinema narrative has not changed that much since the silent film.”

—From a 2015 interview with The A.V. Club

3. ON THE TWO TYPES OF HORROR STORIES

“There are two different stories in horror: internal and external. In external horror films, the evil comes from the outside, the other tribe, this thing in the darkness that we don’t understand. Internal is the human heart.”

—From a 2011 interview with Vulture

4. ON THE IMPORTANCE OF NIGHT OF THE LIVING DEAD

“One movie that showed me it was possible to make a low-budget horror movie was Night of the Living Dead (1968). When I saw that, I was like, 'Wow, that's really effective, but it's obviously low budget.' They didn't have any money but they actually made something cool. That was inspirational to me when I was in film school.”

—From a 2015 interview with Interview Magazine

5. ON THE TRUTH ABOUT HOLLYWOOD

“Film buffs who don't live in Hollywood have a fantasy about what it's like to be a director. Movies and the people who make movies have such glamor associated with them. But the truth is, it's not like that. It's very different. It's hard work. If you were suddenly catapulted into that situation—without any training—you would say after it was over: 'Oh, God! You're kidding! You mean, this is what it's like? This is what they put you through?' Yes, as a matter of fact, it is like this—and it's often worse. People have tried to describe the film business, but it's impossible to describe because it's so crazy. You must know your craft inside out and then pick up the rules as you go along.”

—From an essay for Santa Fe Studios

6. ON THE HORROR OF WATCHING HIS OWN MOVIES

“I don't watch my films. I've seen 'em enough after cutting them and putting the music on. I don't ever want to see them again.”

—From a 2012 interview with Entertainment Weekly

7. ON THE EMOTIONAL TOLL MAKING MOVIES CAN TAKE ON A DIRECTOR

“I’ve been feeling old for years and years, and I think the movie business did it to me. At one point I just did movie after movie, and it starts tearing you down physically—emotionally too, if you do one after another. The stress, the emotional exertion of dealing with others. I’ve worked with really great actors and really difficult actors. The difficult ones are no fun. And the style of the movies today have changed a great deal. To me, I’m not a big fan of handheld. That’s just my tastes. That’s a quick fix for low budget. Let the operator direct it! Walk around. That’s how you burn through the pages. And found footage—how many times do we need to do that?”

—From a 2014 interview with Deadline

8. ON WHAT MAKES A GOOD HORROR FILM

“There’s a very specific secret: It should be scary.”

—From a 2015 interview with The A.V. Club

9. ON THE PERCEPTION OF A MOVIEMAKER

“In England, I'm a horror movie director. In Germany, I'm a filmmaker. In the U.S., I'm a bum.”

—From The Films of John Carpenter

10. ON STANDING OUT

“I don't want to be in the mainstream. I don't want to be a part of the demographics. I want to be an individual. I wear each of my films as a badge of pride. That's why I cherish all my bad reviews. If the critics start liking my movies, then I'm in deep trouble.”

—From an essay for Santa Fe Studios

11. ON MAINTAINING CONTROL

“My years in the business have taught me not to worry about what you can’t control.”

—From a 2007 interview with MovieMaker Magazine

12. ON HIS FAVORITE MOVIES

“I have two different categories of favorite films. One is the emotional favorites, which means these are generally films that I saw when I was a kid; anything you see in your formative years is more powerful, because it really stays with you forever. The second category is films that I saw while I was learning the craft of motion pictures.”

—From a 2011 interview with Rotten Tomatoes

13. ON BEING STUCK IN THE 1980S

“Well, They Live was a primal scream against Reaganism of the '80s. And the '80s never went away. They're still with us. That's what makes They Live look so fresh—it's a document of greed and insanity. It's about life in the United States then and now. If anything, things have gotten worse.”

—From a 2012 interview with Entertainment Weekly

14. ON THE IMPORTANCE OF INSTINCT

“I think every director depends primarily on his instincts. That’s what’s got him where he is, what’s going to carry him through the good times and the bad. I generally go with what I instinctually think I can do well.”

—From a 2011 interview with Vulture

15. ON BEING TYPECAST AS A DIRECTOR

“I haven't just made horror. I've made all sorts of movies. There have been fantasy movies, thrillers, horrors, science fiction. In terms of the ultimate reward, listen, man, when I was a kid, when I was 8 years old, I wanted to be a movie director, and I got to be a movie director. I lived my f*cking dream, you can't get better than that. That's the ultimate.”

—From a 2015 interview with Interview Magazine

16. ON THE REALITY OF MONSTERS

“Monsters in movies are us, always us, one way or the other. They’re us with hats on. The zombies in George Romero’s movies are us. They’re hungry. Monsters are us, the dangerous parts of us. The part that wants to destroy; the part of us with the reptile brain. The part of us that’s vicious and cruel. We express these in our stories as these monsters out there.”

—From a 2011 interview with the Buenos Aires Herald

17. ON MOVIES AS A SENSORY EXPERIENCE

“A movie’s not just the pictures. It’s the story and it’s the perspective and it’s the tempo and it’s the silence and it’s the music—it’s all the stuff that’s going on. All the sensory stuff. Sometimes you can get a lot of suspense going in a non-horror film. It all depends. But, look, if there was one secret way of doing a horror movie then everybody would be doing it.”

—From a 2015 interview with The A.V. Club

18. ON THE UNIVERSAL LANGUAGE OF HORROR

"Horror is a universal language; we're all afraid. We're born afraid, we're all afraid of things: death, disfigurement, loss of a loved one. Everything that I'm afraid of, you're afraid of and vice versa. So everybody feels fear and suspense. We were little kids once and so it's taking that basic human condition and emotion and just f*cking with it and playing with it. You can invent new horrors."

—From a 2015 interview with Interview Magazine

19. ON THE REMAKE TREND

“It’s a brand new world out there in terms of trying to get advertising. There’s so much going on that if you come up with a movie that people have never heard of they don’t pay attention to it—no matter how good it is. So it becomes, 'Let’s remake something that maybe rings a bell and that you’ve heard of before.' That way, you’re already ahead. I’m flattered, but I understand what’s going on. They’re picking everything to remake. I think they’ve just run down the list of other titles and have finally got to mine.”

—From a 2007 interview with MovieMaker Magazine

20. ON THE LASTING INFLUENCE OF HALLOWEEN

“I didn’t think there was any more story [to Halloween], and I didn’t want to do it again. All of my ideas were for the first Halloween—there shouldn’t have been any more! I’m flattered by the fact that people want to remake them, but they remake everything these days, so it doesn’t make me that special. But Michael Myers was an absence of character. And yet all the sequels are trying to explain that. That’s silliness—it just misses the whole point of the first movie, to me. He’s part person, part supernatural force. The sequels rooted around in motivation. I thought that was a mistake. However, I couldn’t stop them from making sequels. So my agents said, ‘Why don’t you become an executive producer and you can share the revenue?’ But I had to write the second movie, and every night I sat there and wrote with a six-pack of beer trying to get through this thing. And I didn’t do a very good job, but that was it. I couldn’t do any more."

—From a 2014 interview with Deadline
