How the Rainbow Became Associated with Gay Rights

Flags with a spectrum of colors have been used for centuries to represent change. There's evidence to suggest that rainbow-colored flags date back at least to the German Peasants' War in the 1500s. The International Co-operative Movement designed a colorful banner to show international unity in 1921. Italy and Greece both use rainbow-striped flags to symbolize peace. And during the Hippie movement of the 1960s, peaceful protesters brought the rainbow equals peace concept back to the forefront.

But how the rainbow became specifically associated with LGBT rights goes back to San Francisco in the late 1970s, and to one artist in particular.

The flag was created by Gilbert Baker in 1978. Born in Kansas in 1951, Baker came out as gay to his parents one Christmas Day after he fell in love. "When I was young, they thought I was from outer space," Baker told CNN. "I was the only gay person they probably knew, and they struggled with that … I came out because I fell in love. It wasn't a terrible, horrible, damn thing. I was in love with somebody, and I wanted to scream it from the rooftops."

Baker worked as an Army medic San Francisco in the early 1970s, and when his time in the Army was over, he decided to stay in the city. He occasionally performed as a drag queen and took part the queer liberation movement, becoming friends with Harvey Milk, the first openly gay person elected to office in California—who urged his friend to create a symbol for gay rights.

In 1976, Baker noticed a proliferation of American flags around San Francisco—a celebration of the country’s bicentennial. "I thought, a flag is different than any other form of art. It’s not a painting, it’s not just cloth, it is not a just logo—it functions in so many different ways," Baker told the Museum of Modern Art (MoMA). "I thought that we needed that kind of symbol, that we needed as a people something that everyone instantly understands. … It was necessary to have the Rainbow Flag because up until that we had the pink triangle from the Nazis—it was the symbol that they would use [to denote gay people]."

His reason for choosing a rainbow was simple: "We needed something beautiful, something from us. The rainbow is so perfect because it really fits our diversity in terms of race, gender, ages, all of those things. Plus, it's a natural flag—it's from the sky!"

Baker chose both where the flag was created and where it flew for the first time very carefully. "I decided the flag needed a birthplace so I didn’t make it at home," he said to MoMA. "I wanted to make it at [the Gay Community Center at 330 Grove Street], with my friends—it needed to have a real connection to nature and community."

Using huge garbage cans filled with natural dye, Baker and his volunteers dyed massive amounts of cotton in eight colors, each with symbolic meaning:

Hot Pink: Sexuality
Red: Life
Orange: Healing
Yellow: Sunlight
Green: Nature
Turquoise: Magic/Art
Blue/Indigo: Serenity/Harmony
Violet: Spirit

When it came time to sew, "it took four hands to move the fabric through the machine," Baker recalled to MoMA. Ironing the two flags—which each measured 30 feet by 60 feet—required 10 people.

The first flags went up at the United Nations Plaza during the San Francisco Gay Freedom Day Parade on June 25, 1978. "When the flag actually went up, it was a very important thing that we raised them—there were two of them—in the United Nations Plaza [in downtown San Francisco]," Baker told MoMA. "Even in those days, my vision and the vision of so many of us was that this was a global struggle and a global human rights issue."

"When it went up and the wind finally took it out of my hands," Baker recalled to CNN in 2015, "it blew my mind."

Baker’s design became popular pretty quickly, but demand for the flag skyrocketed after Harvey Milk was assassinated five months later, on November 27, 1978. As more and more people wanted to show their support for Milk and the LGBT community, it became harder to keep the supply of custom-created eight-striped rainbow banners up; Baker switched to premade rainbow-colored fabric even though it lacked the hot pink stripe. (The dye also had a tendency to run on cotton, so they switched to nylon. "The nylon caught on for two reasons: first of all, it’s very durable, and second, it lights beautifully," Baker told MoMA. "Dupont puts out a great product just for flags, it’s called Oxford Weave and it lights rather like stained glass and in some of the photographs you’ll see the sunlight coming through and it makes a rainbow on the pavement. That’s something that I think really captured the public’s imagination.")

The flag was further modified the following year, when the turquoise stripe was dropped. While accounts differ as to the precise reason, they all come back to a desire to be able to split it in half more easily for display purposes.

Since that time, the rainbow has become the popular symbol of the LGBT community. Baker stayed busy after sewing that first flag in 1978. In 2003, he helped create the world's biggest LGBT flag ever—it stretched a mile and a quarter across Key West, from the Gulf of Mexico to the Atlantic Ocean. Afterward, sections of the flag were then sent to more than 100 cities around the world.

Baker passed away at the age of 65 in 2017. His first rainbow flag is currently in MoMA’s collection.

15 Positively Reinforcing Facts About B.F. Skinner

Burrhus Frederic Skinner was one of the preeminent American psychologists of the 20th century. B.F. Skinner founded “radical behaviorism”—a twist on traditional behaviorism, a field of psychology that focused exclusively on observable human behavior. Thoughts, feelings, and perceptions were cast aside as unobservable.

B.F. Skinner dubbed his own method of observing behavior “operant conditioning,” which posited that behavior is determined solely by its consequences—either reinforcements or punishments. He also coined the term "positive reinforcement." 

To Skinner’s critics, the idea that these “principles of reinforcement,” as he called them, lead to easy “behavior modification” suggested that we do not have free will and are little more than automatons acting in response to stimuli. But his fans considered him visionary. Controversial to the end, B.F. Skinner was well known for his unconventional methods, unusual inventions, and utopian—some say dystopian—ideas about human society.

1. B.F. Skinner invented the "operant conditioning" or "Skinner" box.

Skinner believed that the best way to understand behavior is to look at the causes of an action and its consequences. He called this approach “operant conditioning.” Skinner began by studying rats interacting with an environment inside a box, where they were rewarded with a pellet of food for responding to a stimulus like light or sound with desired behavior. This simple experiment design would over the years take on dark metaphorical meaning: Any environment that had mechanisms in place to manipulate or control behavior could be called a "Skinner box." Recently, some have argued that social media is a sort of digital Skinner box: Likes, clicks, and shares are the pellet-like rewards we get for responding to our environment with certain behavior. Yes, we are the rats.

2. B.F. Skinner believed that all behavior was affected by one of three "operants."

Skinner proposed there were only three “operants” that had affected human behavior. Neutral operants were responses from the environment that had a benign effect on a behavior. Reinforcers were responses that increased the likelihood of a behavior’s repetition. And punishers decreased the likelihood of a behavior’s repetition. While he was correct that behavior can be modified via this system, it’s only one of many methods for doing so, and it failed to take into account how emotions, thoughts, and—as we learned eventually—the brain itself account for changes in behavior.

3. He's responsible for the term "positive reinforcement."

B.F. Skinner eventually moved on to studying pigeons in his Skinner box. The pigeons would peck at a disc to gain access to food at various intervals, and for completing certain tasks. From this Skinner concluded that some form of reinforcement was crucial in learning new behaviors. To his mind, positive reinforcement strengthens a behavior by providing a consequence an individual finds rewarding. He concluded that reinforced behavior tends to be repeated and strengthened.

4. Some critics felt "positive reinforcement" amounted to bribery.

Critics were dubious that Skinner's focus on behavior modification through positive reinforcement of desired behavior could actually change behavior for the long term, and that it was little more than temporary reward, like bribery, for a short-term behavioral change.

5. B.F. Skinner's idea of "negative reinforcement" isn't what you think.

Skinner believed negative reinforcement also helped to strengthen behavior; this doesn't mean exposing an animal or person to a negative stimulus, but rather removing an “unpleasant reinforcer.” The idea was that removing the negative stimulus would feel like a “reward” to the animal or person.

6. B.F. Skinner taught pigeons to play ping-pong.

As part of his research into positive reinforcement, he taught pigeons to play ping-pong as a first step in seeing how trainable they were. He ultimately wanted to teach them to guide bombs and missiles and even convinced the military to fund his research to that effect. He liked working with pigeons because they responded well to reinforcements and punishments, thus validating his theories. We know now that pigeons can be trained in a whole host of tasks, including distinguishing written words from nonsense and spotting cancer.

7. B.F. Skinner's first book, The Behavior of Organisms, broke new ground.

Published in 1938, Skinner’s debut book made the case that simple observation of cause and effect, reward and punishment, were as significant to understanding behavior as other “conceptual or neural processes.”

Skinner believed behavior was everything. Thoughts and feelings were just unreliable byproducts of behaviors, he argued—and therefore dismissed them. Many of his fellow psychologists disagreed. Regardless, Skinner’s theories contributed to a greater understanding of the relationship between stimuli and resulting behavior and may have even laid the groundwork for understanding the brain’s reward circuitry, which centers around the amygdala.

8. B.F. Skinner created the "baby tender."

Skinner was fond of inventions, and having children gave him a new outlet for his tendencies. He designed a special crib for his infant daughter called “the baby tender.” The clear box, with air holes, was heated so that the baby didn't need blankets. Unlike typical cribs, there were no slats in the sides, which he said prevented possible injury. Unsurprisingly, it did not catch on with the public.

9. B.F. Skinner also developed his own "teaching machine."

You may have Skinner to thank for modern school workbooks and test-taking procedures. In 1954 Skinner visited his daughter’s classroom and found himself frustrated with the “inefficiencies” of the teaching procedures. His first "teaching machine"—a very basic program to improve teaching methods for spelling, math, and other school subjects—was little more than a fill-in-the-blank method on workbook or computer. It’s now considered a precursor to computer-assisted learning programs.

10. Skinner imaged an ideal society based on his theories of human behavior.

Skinner admired Henry David Thoreau’s famous book Walden, in which Thoreau writes about his retreat to the woods to get in greater contact with his inner nature. Skinner's "Ten Commandments" for a utopian world include: “(1) No way of life is inevitable. Examine your own closely. (2) If you do not like it, change it. (3) But do not try to change it through political action. Even if you succeed in gaining power, you will not likely be able to use it any more wisely than your predecessors. (4) Ask only to be left alone to solve your problems in your own way. (5) Simplify your needs. Learn how to be happy with fewer possessions.”

11. B.F. Skinner wrote a utopian novel, Walden Two.

Though inspired by Walden, Skinner also felt the book was too self-indulgent, so he wrote his own fictional follow-up with the 1948 novel Walden Two. The book proposed a type of utopian—some say dystopian—society that employed a system of behavior modification based on operant conditioning. This system of rewards and punishments would, Skinner proposed, make people into good citizens:

“We can achieve a sort of control under which the controlled, though they are following a code much more scrupulously than was ever the case under the old system, nevertheless feel free. They are doing what they want to do, not what they are forced to do. That's the source of the tremendous power of positive reinforcement—there's no restraint and no revolt. By careful cultural design, we control not the final behavior, but the inclination to behave—the motives, desires, the wishes.”

12. Some felt Skinner's ideas were reductionist ...

Critics, of which there were many, felt he reduced human behavior to a series of actions and reactions: that an individual human “mind” only existed in a social context, and that humans could be easily manipulated by external cues. He did not put much store in his critics. Even at age 83, just three years before he died, he told Daniel Goleman in a 1987 New York Times article, “I think cognitive psychology is a great hoax and a fraud, and that goes for brain science, too. They are nowhere near answering the important questions about behavior.”

13. ... and others were horrified by Walden Two.

Astronomer and colleague JK Jessup wrote, “Skinner's utopian vision could change the nature of Western civilization more disastrously than the nuclear physicists and biochemists combined.”

14. B.F. Skinner implied that humans had no free will or individual consciousness.

In the late 1960s and early '70s, Skinner wrote several works applying his behavioral theories to society, including Beyond Freedom and Dignity (1971). He drew fire for implying that humans had no free will or individual consciousness but could simply be controlled by reward and punishment. His critics shouldn't have been surprised: this was the very essence of his behaviorism. He, however, was unconcerned with criticism. His daughter Julie S. Vargas has written that “Skinner felt that by answering critics (a) you showed that their criticism affected you; and (b) you gave them attention, thus raising their reputation. So he left replies to others.”

15. He died convinced that the fate of humanity lay in applying his methods of behavioral science to society.

In 1990, he died of leukemia at age 86 after receiving a Lifetime Achievement Award from the American Psychological Association. Proud of his work, he was nonetheless concerned about the fate of humanity and worried “about daily life in Western culture, international conflict and peace, and why people were not acting to save the world.”

10 Amazing Facts About Cherry Blossoms

Cherry blossom season is a major tourist draw for any city that’s lucky enough to grow these ornamental cherry trees. More than 1.5 million people are expected to visit Washington, D.C. this year for its National Cherry Blossom Festival (which kicks off on March 20, 2019) and Japan saw an influx of 2.6 million overseas tourists when its pretty pink flowers started to bloom in March of last year. In celebration of the arrival of spring, here are 10 things you might not know about the trees that produce such picturesque petals.

1. You'll only find cherry blossoms in a handful of countries.

Called sakura in Japan, the cherry blossoms of Yoshino and Kyoto are world-famous. Tourists flock to the country each spring to try their hand at a centuries-old activity called hanami, or “flower viewing.” You don’t have to fly to Japan to see them, though. In the U.S., the cherry blossoms of Washington, D.C., New York City, Philadelphia, St. Louis, Seattle, San Francisco, and Boston are all beautiful in their own way. The flowers can also be viewed in many European and Asian countries, as well as Brazil and Australia in the southern hemisphere.

2. The cherry blossom capital of the world is in the state of Georgia.

Believe it or not, the city of Macon in central Georgia is recognized as the “Cherry Blossom Capital of the World”—at least according to U.S. Congressional records. It’s home to 350,000 Yoshino cherry trees, while Washington, D.C. has fewer than 4000 trees. Those who organize the two cities’ respective cherry blossom festivals have engaged in some playful competition over the years. In 1987, representatives of the Macon festival sent army helmets to TV stations in D.C. “to dramatize the rivalry,” according to an article published at the time in The Record. Representatives in D.C. played it cool, with one spokesperson for the National Park Service stating, “I’m sure they have much more than we have here, but we’re still proud of our celebration.”

3. There are hundreds of cherry tree varieties.

Japan in particular is home to hundreds of types of cherry tree—possibly more than 600, by more liberal estimates. Some types bear fruit, while others don’t. The flowers of many trees change from dark pink to light pink to white throughout the different stages of blossoming, while others progress from greenish yellow to white to pink. One variety, called Kanzan, was bred to have “double blossoms”—or up to 28 petals on each flower, compared to the Yoshino tree’s five petals.

4. They don't bloom for long.

A cherry tree might only remain in bloom for one to two weeks. However, they only keep up their “peak color” for about three days, so it’s best to time your trip wisely if you’re visiting a cherry blossom destination from out of town. The timing depends on a number of factors, including location, heat, and daylight. In D.C., the florets typically start to appear in March, and peak bloom (when 70 percent of the flowers have blossomed) generally occurs in late March or early April. This year, the National Park Service predicts that peak bloom will occur from April 3 to April 6, 2019.

5. Climate change could be making them blossom earlier.

The projected peak bloom dates are right on track for 2019, but that hasn’t always been the case. Some scholars have suggested that the trees are blooming earlier and earlier as the planet gradually gets warmer. Dr. Soo-Hyung Kim, an ecophysiologist at the University of Washington who has studied the phenomenon, says that by 2080 we could expect to see cherry blossoms in D.C. as early as February.

6. You can get arrested for plucking a cherry blossom in Washington, D.C.

Resist the urge to take a cherry blossom home with you as a souvenir. In D.C. at least, breaking off a blossom or branch is viewed as vandalism of federal property. Those who break this rule could receive a citation, or worse, be arrested. (Though usually, law enforcement officers prefer to issue warnings or small fines.) It goes without saying that it’s also illegal to climb the trees. If they sustain damage to their branches, they will never be able to grow new blossoms on that particular bough again.

7. The very first cherry trees to arrive in America were a complete disaster.

In 1909, Japan offered to send 2000 cherry trees to America as a symbol of friendship between the two countries. After all, just a few years earlier, U.S. President Teddy Roosevelt had helped Japan negotiate an end to the Russo-Japanese War. Despite the good intentions, the execution was disastrous. When the trees arrived in D.C. in January 1910, the trees were weak—due to overpruning of their roots—and they were also infested with wood-boring insects. Despite attempts to save them, the trees were ultimately thrown in a pile and burned.

Everyone was pretty embarrassed about the whole ordeal, but Tokyo mayor Yukio Ozaki made a joke to ease some of the tension. “To be honest about it, it has been an American tradition to destroy cherry trees ever since your first president, George Washington,” he said. “So there’s nothing to worry about. In fact, you should be feeling proud.” (Washington's cherry tree story turned out to be untrue, but we digress.) Another shipment of trees was sent, and by 1912, the healthy trees were successfully planted in D.C. by then-First Lady Helen Taft.

8. The cherry trees in one Dutch municipality have proper names.

Located in the largest park in the Netherlands, all 400 cherry blossom trees have proper names. Half of them have traditional Dutch women’s names, and the other half have Japanese women’s names. The Japan Women’s Club gifted the trees in 2000, and you can now find them at Amsterdamse Bos (Amsterdam Forest) in the Amstelveen municipality.

9. Both the blossoms and leaves are edible.

Pocky snacks

In Japan, no part of the cherry blossom tree goes to waste. The preserved leaves are used as edible mochi wrappers (a rice cake filled with sweet bean paste), and a number of seasonal snacks feature sakura as a key ingredient. Sakura-infused versions of Pepsi, Coke, tea, and even Starbucks lattes are all popular drinks. You can also find two varieties of Kit Kats—sakura and roasted soy bean, and sakura sake—as well as Pocky snack sticks that taste like sakura and matcha (green tea).

So what do cherry blossoms taste like? They have a “light, flowery, slightly cherry flavor,” according to Gabe Perez, social media director at Japan Crate, a subscription box service that ships many of the aforementioned snacks, plus other Japanese products, to customers.

10. They were the inspiration behind a record-setting LEGO sculpture.

LEGOLAND Japan, a theme park in Nagoya, set a Guinness World Record in 2018 for the largest LEGO brick cherry blossom tree ever made (although we’re not sure how much competition they had). The tree stood 14 feet tall, weighed over 7000 pounds, and consisted of more than 800,000 LEGO bricks.
