Free speech on campus holds the cure to America's growing polarization
Outrage culture is causing provocative issues to be pushed out of public discourse and important artworks to be literally white-washed. Teaching civil discourse at universities is key to sustaining the American experiment.
- In July 2019, a California school board voted unanimously to paint over an 83-year-old, 1,600-square-foot mural chronicling the life of George Washington – in part depicting dead Native Americans and laboring slaves – over concerns that the painting presented traumatic content.
- The mural, by Stanford University art professor Victor Arnautoff, was created as a pointed critique of Washington, a slave owner, and a society built on land that belonged to Native Americans.
- The reaction to Arnautoff's deliberately disturbing artwork is characteristic of America's growing outrage culture, which removes the opportunity for people to practice the skills they require to have difficult conversations.
In early July, a California school board voted unanimously to paint over an 83-year-old, 1,600-square-foot mural chronicling the life of George Washington that hangs over a staircase in George Washington High School in San Francisco. The reason: Concerns the images of minorities, including white colonists stepping over a dead Native-American and slaves laboring at Washington's Mount Vernon estate, will traumatize students.
In his historic painting, Russian-American artist and self-described communist Victor Arnautoff, a Stanford University art professor who specialized in social realism, was pointedly critiquing Washington, a slave owner, and a society built on land that belonged to Native Americans. Eliciting reactions from students is the point. It's an invitation to learn about this history that is often swept under the rug, and it makes a pointed assertion about the importance of countering the prejudice it reveals. Censorship often harms the very people it's intended to protect – in this case, it would strip students of an important opportunity to grapple with racism in our past and deprive them of an opportunity to discuss solutions to the problems that history has created in the present.
The vote to destroy a "significant monument of anti-racism," reads an open letter signed by more than 500 academics across the country, "is a gross violation of logic and sense." It is. But that's not all. The school board's reaction to Arnautoff's deliberately disturbing artwork is characteristic of broader cultural trends.
"[W]e're seeing the symptoms of growing outrage culture—an environment in which controversial or offensive ideas aren't met with challenge but calls to push them out of public discourse altogether."
With social media facilitating our tribal instincts to gang up on the 'other,' universities grappling with pressure to remove faculty who work on provocative issues, and iconic works of art being literally whitewashed, we're seeing the symptoms of growing outrage culture—an environment in which controversial or offensive ideas aren't met with challenge but calls to push them out of public discourse altogether.
Research confirms the trend too. A new Pew study found that nearly 60 percent of Americans are "not confident that others can hold civil conversations with people who have different views." Even more alarming, a recent academic paper found many people in each political party don't only disagree with the other, they believe members of the opposing party are "downright evil." And the latest Gallup/Knight campus expression study found that students today (61 percent) are more likely than they were in 2016 (54 percent) to think the climate on their campus prevents people from speaking their mind because others might take offense.
The student findings are notable when viewed as one symptom of this trend. They point to the fact that challenges facing campus speech aren't unique to the academy. This is a cultural problem, and we're seeing its reverberations across sectors of society – including higher education.
If it's a cultural issue and not a sector-specific one, it changes how we approach the solution. In fact, by zooming out, universities come into focus as uniquely positioned to help America address our growing divisiveness. Consider the environment that campuses traditionally provide for conversation and deliberation. They invite students to understand diverse views in their intellectual complexity while practicing the skills for having these important and difficult conversations.
"These academic entrepreneurs are asking tough questions, conceiving new classes, and promoting a culture in which generally enlightening, often-discomfiting, ideologically-impartial programs are seen for what they truly are – an opportunity to learn."
Policy change can play a role in aiding that ideal. Though the past few years have seen a number of gross overreaches from state houses – bills to dictate what classes can be taught, establish partisan litmus tests for staff hires, and mandate minimum punishments for students – there's a role for principled, targeted policies in shoring up legal protections for free expression on college campuses. In a recent essay Greg Lukianoff, president and CEO of the Foundation for Individual Rights in Education (FIRE), pointed out that the percentage of colleges that maintain severely restrictive speech policies declined from 74.2 percent in 2009 to 28.5 percent in 2018, while at the same time a number of problematic Department of Education regulations have been repealed or revised. That is, in part, attributable to policies tailored to addressing those barriers.
While legal protections of free expression alone don't foster an open environment, they help clear the way for civil discourse, open inquiry, and peaceful pluralism in general. And in that space, we're seeing a largely untold story unfolding through the efforts of innovative, path-breaking scholars who are expanding opportunities to come together in productive and scientific exploration. Courageous crusaders like those at Interfaith Youth Core who are gathering students, faculty, and staff from different cultures and backgrounds to build the will, skill, and knowledge to respectfully engage deep difference. Leaders at the newly growing HBCU Debate League who are giving students a platform to grapple with myriad ideas. And countless others tailoring opportunities to their own campuses at schools across the country.
These academic entrepreneurs are asking tough questions, conceiving new classes, and promoting a culture in which generally enlightening, often-discomfiting, ideologically-impartial programs are seen for what they truly are – an opportunity to learn.
These projects stand to equip individuals to overcome the challenges of the present moment. And we have reason for hope. The American experiment – distinct from every country before it – is built not just on tolerance of difference but the invitation of it. Our diverse, dynamic society, with its rich mix of religious, cultural, ideological, and other differences, is made possible by civil liberties and a culture that values them. And higher education is at its best a microcosm of that.
Understanding what tolerance means in a highly polarized America
A new episode of "Your Brain on Money" illuminates the strange world of consumer behavior and explores how brands can wreak havoc on our ability to make rational decisions.
- Effective branding can not only change how you feel about a company, it can actually change how your brain is wired.
- Our new series "Your Brain on Money," created in partnership with Million Stories, recently explored the surprising ways brands can affect our behavior.
- Brands aren't going away. But you can make smarter decisions by slowing down and asking yourself why you're making a particular purchase.
How Apple and Nike have branded your brain | Your Brain on Money | Big Think youtu.be
Brands can manipulate our brains in surprisingly profound ways. They can change how we conceptualize ourselves and how we broadcast our identities out to the social world. They can make us feel emotions that have nothing to do with the functions of their products. And they can even sort us into tribes.
To grasp the power of brands, look to Apple. In the 1990s, the company was struggling to compete with Microsoft over the personal computer market. Despite flirting with bankruptcy in the mid-1990s, Apple turned itself around to eventually become the most valuable company in the world.
That early-stage success wasn't due to superior products.
"People talk about technology, but Apple was a marketing company," John Sculley, a former Apple marketing executive, told The Guardian in 1997. "It was the marketing company of the decade."
So, how exactly does branding make people willing to wait hours in line to buy a $1,000 smartphone, or pay exorbitant prices for a pair of sneakers?
Branding and the brain
For more than a century, brands have capitalized on the fact that effective marketing is much more than simply touting the merits of a product. Some ads have nothing to do with the product at all. In 1871, for example, Pearl Tobacco started advertising their cigarettes through branded posters and trading cards that featured exposed women, a trend that continues to this day.
It's crude, sure. But research shows that it's also remarkably effective, even on monkeys. Why? The answer seems to center on how our brains pay special attention to information from the social world.
"In theory, ads that associate sex or status with specific brands or products activate the brain mechanisms that prioritize social information, and turning on this switch may bias us toward the product," wrote neuroscience professor Michael Platt for Scientific American.
Brands can burrow themselves deep into our subconscious. Through ad campaigns, brands can form a web of associations and memories in our brains. When these connections are robust and positive, it can change our behavior, nudging us to make "no-brainer" purchases when we encounter the brand at the store.
It's a marketing principle that's related to the work of Daniel Kahneman, a psychologist and economist who won the 2002 Nobel Memorial Prize in Economic Sciences. In his book "Thinking Fast and Slow", Kahneman separates thinking into two broad categories, or systems:
- System 1 is fast and automatic, requiring little effort or voluntary control.
- System 2 is slow and requires subjective deliberation and logic.
Brands that tap into "system 1" are likely to dominate the competition. After all, it's far easier for us as consumers to automatically reach for a familiar brand than it is to analyze all of the available information and make an informed choice. Still, the most successful brands can have an even deeper impact on our psychology, one that causes us to conceptualize them as something like a family member.
A peculiar relationship with brands
Apple has one of the most loyal customer bases in the world, with its brand loyalty hitting an all-time high earlier this year, according to a SellCell survey of more than 5,000 U.S.-based smartphone users.
Qualitatively, how does that loyalty compare to Samsung users? To find out, Platt and his team conducted a study in which functional magnetic resonance imaging scanned the brains of Samsung and Apple users as they viewed positive, negative, and neutral news about each company. The results revealed stark differences between the two groups, as Platt wrote in "The Leader's Brain":
"Apple users showed empathy for their own brand: The reward-related areas of the brain were activated by good news about Apple, and the pain and negative feeling parts of the brain were activated by bad news. They were neutral about any kind of Samsung news. This is exactly what we see when people empathize with other people—particularly their family and friends—but don't feel the joy and pain of people they don't know."
Meanwhile, Samsung users didn't show any significant pain- or pleasure-related brain activity when they saw good or bad news about the company.
"Interestingly, though, the pain areas were activated by good news about Apple, and the reward areas were activated by bad news about the rival company—some serious schadenfreude, or "reverse empathy," Platt wrote.
The results suggest a fundamental difference between the brands: Apple has formed strong emotional and social connections with consumers, Samsung has not.
Brands and the self
Does having a strong connection with a brand justify paying higher prices for their products? Maybe. You could have a strong connection with Apple or Nike and simultaneously think the quality of their products justifies the price.
But beyond product quality lies identity. People have long used objects and clothing to express themselves and signal their affiliation with groups. From prehistoric seashell jewelry to Air Jordans, the things people wear and associate with signal a lot of information about how they conceptualize themselves.
Since the 1950s, researchers have examined the relationship between self-image and brand preferences. This body of research has generally found that consumers tend to prefer brands whose products fit well with their self-image, a concept known as self-image congruity.
By choosing brands that don't disrupt their self-image, consumers are able not only to express themselves personally, but also broadcast a specific version of themselves into the social world. That might sound self-involved. But on the other hand, humans are social creatures who use information from the social world to make decisions, so it's virtually impossible for us not to make inferences about people based on how they present themselves.
Americus Reed II, a marketing professor at the University of Pennsylvania, told Big Think:
"When I make choices about different brands, I'm choosing to create an identity. When I put that shirt on, when I put that shirt on — those jeans, that hat — someone is going to form an impression about what I'm about. So, if I'm choosing Nike over Under Armour, I'm choosing a kind of different way to express affiliation with sport. The Nike thing is about performance. The Under Armour thing is about the underdog. I have to choose which of these different conceptual pathways is most consistent with where I am in my life."
Making smarter decisions
Brands may have some power over us when we're facing a purchasing decision. So, considering brands aren't going away, what can we do to make better choices? The best strategy might be to slow down and try to avoid making "automatic" purchasing decisions that are characteristic of Kahneman's fast "system 1" mode of thinking.
"I think it's important to always pause and think a little bit about, "Okay, why am I buying this product?" Platt said.
As for getting out of the brand game altogether? Good luck.
"I've heard lots of people push back and say, "I'm not into brands,"" Reed II said. "I take a very different view. In some senses, they're not doing anything different than what someone who affiliates with a brand is doing. They have a brand. It's just an anti-brand brand."
Powerful branding can not only change how you feel about a company, it can actually change how your brain is wired.
- Powerful branding can not only change how you feel about a company, it can actually change how your brain is wired.
- "We love to think of ourselves as rational. That's not how it works," says UPenn professor Americus Reed II about our habits (both conscious and subconscious) of paying more for items based primarily on the brand name. Effective marketing causes the consumer to link brands like Apple and Nike with their own identity, and that strong attachment goes deeper than receipts.
- Using MRI, professor and neuroscientist Michael Platt and his team were able to see this at play. When reacting to good or bad news about the brand, Samsung users didn't have positive or negative brain responses, yet they did have "reverse empathy" for bad news about Apple. Meanwhile, Apple users showed a "brain empathy response for Apple that was exactly what you'd see in the way you would respond to somebody in your family."
Evolution proves to be just about as ingenious as Nikola Tesla
- For the first time, scientists developed 3D scans of shark intestines to learn how they digest what they eat.
- The scans reveal an intestinal structure that looks awfully familiar — it looks like a Tesla valve.
- The structure may allow sharks to better survive long breaks between feasts.
Considering how much sharks are feared by humans, it is a bit of a surprise that scientists don't know much about the predators. For example, until recently, sharks were thought to be solitary creatures searching the seas for food on their own. Now it appears that some sharks are quite social.
Another mystery is how these prehistoric swimming and eating machines digest food. Although scientists have made 2D sketches of captured sharks' digestive systems based on dissections, there is a limit to what can be learned in this way. Professor Adam Summers at University of Washington's Friday Harbor Labs says:
"Intestines are so complex, with so many overlapping layers, that dissection destroys the context and connectivity of the tissue. It would be like trying to understand what was reported in a newspaper by taking scissors to a rolled-up copy. The story just won't hang together."
Summers is co-author of a new study that has produced the first 3D scans of a shark's intestines, which turns out to have a strange, corkscrew structure. What's even more bizarre is that it resembles the amazing one-way valve designed by inventor Nikola Tesla in 1920. The research is published in the journal Proceedings of the Royal Society B.
What a 3D model reveals

According to the study's lead author Samantha Leigh, "It's high time that some modern technology was used to look at these really amazing spiral intestines of sharks. We developed a new method to digitally scan these tissues and now can look at the soft tissues in such great detail without having to slice into them."
"CT scanning is one of the only ways to understand the shape of shark intestines in three dimensions," adds Summers. The researchers scanned the intestines of nearly three dozen different shark species.
It is believed that sharks go for extended periods — days or even weeks — between big meals. The scans reveal that food passes slowly through the intestine, affording sharks' digestive system the time to fully extract its nutrient value. The researchers hypothesize that such a slow digestive process may also require less energy.
It could be that this slow digestion is more susceptible to back flow given that the momentum of digested food through the tract must be minimal. Perhaps that is why sharks evolved something so similar to a Tesla valve.

Tesla's "valvular conduit," or what the world now calls a "Tesla valve," is a one-way valve with no moving parts. Its brilliance is based in fluid dynamics and only now coming to be fully appreciated. Essentially, a series of teardrop-shaped loops arranged along the length of the valve allow water to flow easily in one direction but not in the other. Modern tests reveal that at low flow rates, water can travel through the valve either way, but at high flow rates, the design kicks in. According to mathematician Leif Ristroph:
"Crucially, this turn-on comes with the generation of turbulent flows in the reverse direction, which 'plug' the pipe with vortices and disrupting currents. Moreover, the turbulence appears at far lower flow rates than have ever previously been observed for pipes of more standard shapes — up to 20 times lower speed than conventional turbulence in a cylindrical pipe or tube. This shows the power it has to control flows, which could be used in many applications."
A deeper dive
Summers suggests the scans are just the beginning. "The vast majority of shark species, and the majority of their physiology, are completely unknown," says Summers, adding that "every single natural history observation, internal visualization, and anatomical investigation shows us things we could not have guessed at."
To this end, the researchers plan to use 3D printing to produce models through which they can observe the behavior of different substances passing through them — after all, sharks typically eat fish, invertebrates, mammals, and seagrass. They also plan to explore with engineers ways in which the shark intestine design could be used industrially, perhaps for the treatment of wastewater or for filtering microplastics.
It could fairly be said, though, that Nikola Tesla was 100 years ahead of them.
