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
Research shows that those who spend more time speaking tend to emerge as the leaders of groups, regardless of their intelligence.
If you want to become a leader, start yammering. It doesn't even necessarily matter what you say. New research shows that groups without a leader can find one if somebody starts talking a lot.
This phenomenon, described by the "babble hypothesis" of leadership, depends neither on group member intelligence nor personality. Leaders emerge based on the quantity of speaking, not quality.
Researcher Neil G. MacLaren, lead author of the study published in The Leadership Quarterly, believes his team's work may improve how groups are organized and how individuals within them are trained and evaluated.
"It turns out that early attempts to assess leadership quality were found to be highly confounded with a simple quantity: the amount of time that group members spoke during a discussion," shared MacLaren, who is a research fellow at Binghamton University.
While we tend to think of leaders as people who share important ideas, leadership may boil down to whoever "babbles" the most. Understanding the connection between how much people speak and how they become perceived as leaders is key to growing our knowledge of group dynamics.
The power of babble
The research involved 256 college students, divided into 33 groups of four to ten people each. They were asked to collaborate on either a military computer simulation game (BCT Commander) or a business-oriented game (CleanStart). The players had ten minutes to plan how they would carry out a task and 60 minutes to accomplish it as a group. One person in the group was randomly designated as the "operator," whose job was to control the user interface of the game.
To determine who became the leader of each group, the researchers asked the participants both before and after the game to nominate one to five people for this distinction. The scientists found that those who talked more were also more likely to be nominated. This remained true after controlling for a number of variables, such as previous knowledge of the game, various personality traits, or intelligence.

In an interview with PsyPost, MacLaren shared that "the evidence does seem consistent that people who speak more are more likely to be viewed as leaders."
Another find was that gender bias seemed to have a strong effect on who was considered a leader. "In our data, men receive on average an extra vote just for being a man," explained MacLaren. "The effect is more extreme for the individual with the most votes."
The great theoretical physicist Steven Weinberg passed away on July 23. This is our tribute.
- The recent passing of the great theoretical physicist Steven Weinberg brought back memories of how his book got me into the study of cosmology.
- Going back in time, toward the cosmic infancy, is a spectacular effort that combines experimental and theoretical ingenuity. Modern cosmology is an experimental science.
- The cosmic story is, ultimately, our own. Our roots reach down to the earliest moments after creation.
When I was a junior in college, my electromagnetism professor had an awesome idea. Apart from the usual homework and exams, we were to give a seminar to the class on a topic of our choosing. The idea was to gauge which area of physics we would be interested in following professionally.
Professor Gilson Carneiro knew I was interested in cosmology and suggested a book by Nobel Prize Laureate Steven Weinberg: The First Three Minutes: A Modern View of the Origin of the Universe. I still have my original copy in Portuguese, from 1979, that emanates a musty tropical smell, sitting on my bookshelf side-by-side with the American version, a Bantam edition from 1979.
Inspired by Steven Weinberg
Books can change lives. They can illuminate the path ahead. In my case, there is no question that Weinberg's book blew my teenage mind. I decided, then and there, that I would become a cosmologist working on the physics of the early universe. The first three minutes of cosmic existence — what could be more exciting for a young physicist than trying to uncover the mystery of creation itself and the origin of the universe, matter, and stars? Weinberg quickly became my modern physics hero, the one I wanted to emulate professionally. Sadly, he passed away July 23rd, leaving a huge void for a generation of physicists.
What excited my young imagination was that science could actually make sense of the very early universe, meaning that theories could be validated and ideas could be tested against real data. Cosmology, as a science, only really took off after Einstein published his paper on the shape of the universe in 1917, two years after his groundbreaking paper on the theory of general relativity, the one explaining how we can interpret gravity as the curvature of spacetime. Matter doesn't "bend" time, but it affects how quickly it flows. (See last week's essay on what happens when you fall into a black hole).
The Big Bang Theory
For most of the 20th century, cosmology lived in the realm of theoretical speculation. One model proposed that the universe started from a small, hot, dense plasma billions of years ago and has been expanding ever since — the Big Bang model; another suggested that the cosmos stands still and that the changes astronomers see are mostly local — the steady state model.
Competing models are essential to science but so is data to help us discriminate among them. In the mid 1960s, a decisive discovery changed the game forever. Arno Penzias and Robert Wilson accidentally discovered the cosmic microwave background radiation (CMB), a fossil from the early universe predicted to exist by George Gamow, Ralph Alpher, and Robert Herman in their Big Bang model. (Alpher and Herman published a lovely account of the history here.) The CMB is a bath of microwave photons that permeates the whole of space, a remnant from the epoch when the first hydrogen atoms were forged, some 400,000 years after the bang.
The existence of the CMB was the smoking gun confirming the Big Bang model. From that moment on, a series of spectacular observatories and detectors, both on land and in space, have extracted huge amounts of information from the properties of the CMB, a bit like paleontologists that excavate the remains of dinosaurs and dig for more bones to get details of a past long gone.
How far back can we go?
Confirming the general outline of the Big Bang model changed our cosmic view. The universe, like you and me, has a history, a past waiting to be explored. How far back in time could we dig? Was there some ultimate wall we cannot pass?
Because matter gets hot as it gets squeezed, going back in time meant looking at matter and radiation at higher and higher temperatures. There is a simple relation that connects the age of the universe and its temperature, measured in terms of the temperature of photons (the particles of visible light and other forms of invisible radiation). The fun thing is that matter breaks down as the temperature increases. So, going back in time means looking at matter at more and more primitive states of organization. After the CMB formed 400,000 years after the bang, there were hydrogen atoms. Before, there weren't. The universe was filled with a primordial soup of particles: protons, neutrons, electrons, photons, and neutrinos, the ghostly particles that cross planets and people unscathed. Also, there were very light atomic nuclei, such as deuterium and tritium (both heavier cousins of hydrogen), helium, and lithium.
So, to study the universe after 400,000 years, we need to use atomic physics, at least until large clumps of matter aggregate due to gravity and start to collapse to form the first stars, a few millions of years after. What about earlier on? The cosmic history is broken down into chunks of time, each the realm of different kinds of physics. Before atoms form, all the way to about a second after the Big Bang, it's nuclear physics time. That's why Weinberg brilliantly titled his book The First Three Minutes. It is during the interval between one-hundredth of a second and three minutes that the light atomic nuclei (made of protons and neutrons) formed, a process called, with poetic flair, primordial nucleosynthesis. Protons collided with neutrons and, sometimes, stuck together due to the attractive strong nuclear force. Why did only a few light nuclei form then? Because the expansion of the universe made it hard for the particles to find each other.
What about the nuclei of heavier elements, like carbon, oxygen, calcium, gold? The answer is beautiful: all the elements of the periodic table after lithium were made and continue to be made in stars, the true cosmic alchemists. Hydrogen eventually becomes people if you wait long enough. At least in this universe.
In this article, we got all the way up to nucleosynthesis, the forging of the first atomic nuclei when the universe was a minute old. What about earlier on? How close to the beginning, to t = 0, can science get? Stay tuned, and we will continue next week.
To Steven Weinberg, with gratitude, for all that you taught us about the universe.
Long before Alexandria became the center of Egyptian trade, there was Thônis-Heracleion. But then it sank.
Before Alexander the Great established Alexandria around 331 BCE, one of Egypt's primary ports on the Mediterranean Sea between the sixth and fourth centuries BCE was a place called Thônis-Heracleion.
Now researchers from the European Institute for Underwater Archaeology (IEASM), the same organization that first found the city in 2001, have announced the discovery of a couple of fascinating items from the city's heyday. Pinned beneath fallen temple stones is a surprisingly intact Egyptian military vessel from the second century BCE, and researchers have excavated a large cemetery from the fourth century BCE.
Thônis-Heracleion was one of the two primary access points to ancient Egypt from the Mediterranean. (The other, Canopus, was discovered in 1999.) For millennia, experts assumed Thônis-Heracleion were two different lost cities, but it's now known that Thônis is simply the city's Egyptian name, while Heracleion is its Greek name.
Thônis-Heracleion had been the stuff of legend before it was located, mentioned only in rare ancient texts and stone inscriptions. Herodotus seems to have been referring to Thônis-Heracleion's temple of Amun as the place where Heracles first arrived in Egypt. He also described a visit there by Helen with her lover Paris just before the outbreak of the Trojan War. In addition, 400 years later, geographer Strabo wrote that Heraclion, containing the temple of Heracles, had been located opposite Canopus across a branch of the Nile. Today we know Thônis-Heracleion's location as Egypt's Abu Qir Bay. The sunken port is about 6.5 kilometers from the coast and lies beneath ten meters of water.
Both Thônis-Heracleion and Canopus were wealthy in their day, and the temple was an important religious center. This all ended when the Egyptian dynasty created by Ptolemy set out to establish Alexandria as Egypt's center. Thônis-Heracleion and Canopus' trade — and thus wealth — was diverted to the new capital.
It was perhaps just as well, given that natural forces eventually destroyed Thônis-Heracleion. Located on the Mediterranean, the ground upon which it was built became saturated and eventually began to destabilize and liquefy. The temple of Amun probably collapsed around 140 BCE. A series of earthquakes sealed the cty's' fate around 800 CE, sending a 100 square-kilometer chunk of the Nile delta on which it was constructed under the waves. The Mediterranean's rising sea level over the next couple thousand years completed the drowning of Thônis-Heracleion.
Researchers have recovered a large collection of Thônis-Heracleion's treasures revealing an economically rich culture. Coins, bronze statuettes, and over 700 ancient ship anchors have been pulled from the waters. Divers have also identified over 70 shipwrecks. A giant statue of the Nile god Hapi took two and a half years to bring up.

The newly discovered ship was found beneath 16 feet of hard clay, "thanks to cutting-edge prototype sub-bottom profiler electronic equipment," says Ayman Ashmawy of the Egyptian Ministry of Tourism and Antiques.
The military vessel had been moored in Thônis-Heracleion when the temple of Amun collapsed. The temple's enormous blocks fell onto the ship, sinking it. The boat is a rare find — only one other ship of its period has been found. As underwater archaeologist Franck Goddio, one of the scientists who found the city, puts it, "Finds of fast ships from this age are extremely rare."
At 80 feet long, the boat is six times as long as it is wide. Like its dually-named city, it's an amalgam of Greek and Egyptian ship-building techniques. According to expert Ehab Fahmy, head of the Central Department of Underwater Antiquities at IEASM, the boat has some classical construction features such as mortar and tenon joints. On the other hand, it was built to be rowed, and some of its wood was reused lumber, signature traits of Egyptian boat design. Its flat bottom suggests it was built for navigating the shallows of the Nile delta where the river flows into the Mediterranean.
Also found alongside the city's submerged northeastern entrance canal was a large Greek cemetery. The funerary is adorned with opulent remembrances, including a mask made of gold, shown above. A statement by the Egyptian Ministry of Tourism and Antiques describes its significance, as reported by Reuters:
"This discovery beautifully illustrates the presence of the Greek merchants who lived in that city. They built their own sanctuaries close to the huge temple of Amun. Those were destroyed simultaneously and their remains are found mixed with those of the Egyptian temple."
Excavation is ongoing, with more of Egypt's ancient history no doubt waiting beneath the waves.
