Why highly intelligent people make the worst leaders
Here’s the ideal IQ for a leader who manages the average team of humans.
What qualities define a good leader? Is it vision, the ability to understand and negotiate with people, drive, an expectation of excellence, or a stunningly brilliant intellect? A new study finds that the last one may actually be a hindrance. Those who are exceedingly intelligent, while still some of the top producers, don’t necessarily make the best leaders, it finds.
Researchers at the University of Lausanne in Switzerland, led by John Antonakis, set out to test the assumption that the brightest people make the best leaders. Their results were published in the Journal of Applied Psychology. This team was building on the work of UC psychology professor Dean Keith Simonton. He theorized that there’s a sweet spot where peak performance is reached, when the intelligence of the leader correlates with that of the followers.
We expect leaders to be smarter than us, but not too smart, according to Prof. Simonton. While the average IQ is 100-110, the optimal IQ for someone managing a team of average folks, would be 120-125, no more than 1.2 standard deviations above the mean. This relationship is called curvilinear, represented when graphed as an inverted U.

In the Swiss study, 379 middle managers from companies within 30 different, mostly European countries, participated. They were followed over six years and their leadership styles evaluated periodically. Researchers gave participants the Wonderlic Personnel Test, which assesses both personality and IQ. Their scores were spread across the spectrum. Antonakis and colleagues matched these with the Multifactor Leadership Questionnaire, which evaluates a manager’s leadership style and how effective it is.
Subordinates and peers at each participant's job filled these out. The managers were evaluated by seven to eight people each. Personality and intelligence were the key indicators on how effective a leader was. A higher IQ meant a better relationship, up until the leader’s IQ reached above 120. Those with higher intelligence, beyond 128, were found to be less effective.
Bucking another stereotype, researchers uncovered that women tended to express more effective leadership styles. A little over 26% of the participants were women. Older managers scored higher too, but to a lesser extent. What these results show is that balance is important. Intelligence does benefit leadership, Antonakis says, but only if it’s balanced with other parts of one’s personality, like agreeableness and charisma.
Mostly, it comes down to good people skills. Conscientiousness surprisingly didn’t play too much into effective leadership. Of course, whether one is an effective leader or not depends on the IQ of the group. So there isn’t exactly a perfect level of intelligence for a leader to have.
Why do the smartest leaders often fail to reach subordinates? In Simonton’s work, he and colleagues believe that they often put forth more sophisticated plans than others, meaning team members might fail to understand all the intricacies, and thus fail to execute them well. Another problem: complex communication styles might fail to influence others. Also, if a manager comes off as too intellectual, it sets him or her apart. In other words, it makes subordinates feel the leader is not one of them. In the words of the study's authors:
To conclude, Sheldon Cooper, the genius physicist from “The Big Bang Theory” TV series is often portrayed as being detached and distant from normal folk, particularly because of his use of complex language and arguments. However... Sheldon could still be a leader—if he can find a group of followers smart enough to appreciate his prose!
There are shortcomings to this model. It originally only looked at simulations and perceptions rather than actual work environments and performance. This latest study was the first to really put Simonton’s theory to the test.

It's just the current cycle that involves opiates, but methamphetamine, cocaine, and others have caused the trajectory of overdoses to head the same direction
- It appears that overdoses are increasing exponentially, no matter the drug itself
- If the study bears out, it means that even reducing opiates will not slow the trajectory.
- The causes of these trends remain obscure, but near the end of the write-up about the study, a hint might be apparent
Through computationally intensive computer simulations, researchers have discovered that "nuclear pasta," found in the crusts of neutron stars, is the strongest material in the universe.
- The strongest material in the universe may be the whimsically named "nuclear pasta."
- You can find this substance in the crust of neutron stars.
- This amazing material is super-dense, and is 10 billion times harder to break than steel.
Superman is known as the "Man of Steel" for his strength and indestructibility. But the discovery of a new material that's 10 billion times harder to break than steel begs the question—is it time for a new superhero known as "Nuclear Pasta"? That's the name of the substance that a team of researchers thinks is the strongest known material in the universe.
Unlike humans, when stars reach a certain age, they do not just wither and die, but they explode, collapsing into a mass of neurons. The resulting space entity, known as a neutron star, is incredibly dense. So much so that previous research showed that the surface of a such a star would feature amazingly strong material. The new research, which involved the largest-ever computer simulations of a neutron star's crust, proposes that "nuclear pasta," the material just under the surface, is actually stronger.
The competition between forces from protons and neutrons inside a neutron star create super-dense shapes that look like long cylinders or flat planes, referred to as "spaghetti" and "lasagna," respectively. That's also where we get the overall name of nuclear pasta.

The researchers' computer simulations needed 2 million hours of processor time before completion, which would be, according to a press release from McGill University, "the equivalent of 250 years on a laptop with a single good GPU." Fortunately, the researchers had access to a supercomputer, although it still took a couple of years. The scientists' simulations consisted of stretching and deforming the nuclear pasta to see how it behaved and what it would take to break it.
While they were able to discover just how strong nuclear pasta seems to be, no one is holding their breath that we'll be sending out missions to mine this substance any time soon. Instead, the discovery has other significant applications.
One of the study's co-authors, Matthew Caplan, a postdoctoral research fellow at McGill University, said the neutron stars would be "a hundred trillion times denser than anything on earth." Understanding what's inside them would be valuable for astronomers because now only the outer layer of such starts can be observed.
"A lot of interesting physics is going on here under extreme conditions and so understanding the physical properties of a neutron star is a way for scientists to test their theories and models," Caplan added. "With this result, many problems need to be revisited. How large a mountain can you build on a neutron star before the crust breaks and it collapses? What will it look like? And most importantly, how can astronomers observe it?"
Another possibility worth studying is that, due to its instability, nuclear pasta might generate gravitational waves. It may be possible to observe them at some point here on Earth by utilizing very sensitive equipment.
The team of scientists also included A. S. Schneider from California Institute of Technology and C. J. Horowitz from Indiana University.

Scientists think constructing a miles-long wall along an ice shelf in Antarctica could help protect the world's largest glacier from melting.
- Rising ocean levels are a serious threat to coastal regions around the globe.
- Scientists have proposed large-scale geoengineering projects that would prevent ice shelves from melting.
- The most successful solution proposed would be a miles-long, incredibly tall underwater wall at the edge of the ice shelves.
The world's oceans will rise significantly over the next century if the massive ice shelves connected to Antarctica begin to fail as a result of global warming.
To prevent or hold off such a catastrophe, a team of scientists recently proposed a radical plan: build underwater walls that would either support the ice or protect it from warm waters.
In a paper published in The Cryosphere, Michael Wolovick and John Moore from Princeton and the Beijing Normal University, respectively, outlined several "targeted geoengineering" solutions that could help prevent the melting of western Antarctica's Florida-sized Thwaites Glacier, whose melting waters are projected to be the largest source of sea-level rise in the foreseeable future.
An "unthinkable" engineering project
"If [glacial geoengineering] works there then we would expect it to work on less challenging glaciers as well," the authors wrote in the study.
One approach involves using sand or gravel to build artificial mounds on the seafloor that would help support the glacier and hopefully allow it to regrow. In another strategy, an underwater wall would be built to prevent warm waters from eating away at the glacier's base.
The most effective design, according to the team's computer simulations, would be a miles-long and very tall wall, or "artificial sill," that serves as a "continuous barrier" across the length of the glacier, providing it both physical support and protection from warm waters. Although the study authors suggested this option is currently beyond any engineering feat humans have attempted, it was shown to be the most effective solution in preventing the glacier from collapsing.

An example of the proposed geoengineering project. By blocking off the warm water that would otherwise eat away at the glacier's base, further sea level rise might be preventable.
But other, more feasible options could also be effective. For example, building a smaller wall that blocks about 50% of warm water from reaching the glacier would have about a 70% chance of preventing a runaway collapse, while constructing a series of isolated, 1,000-foot-tall columns on the seafloor as supports had about a 30% chance of success.
Still, the authors note that the frigid waters of the Antarctica present unprecedently challenging conditions for such an ambitious geoengineering project. They were also sure to caution that their encouraging results shouldn't be seen as reasons to neglect other measures that would cut global emissions or otherwise combat climate change.
"There are dishonest elements of society that will try to use our research to argue against the necessity of emissions' reductions. Our research does not in any way support that interpretation," they wrote.
"The more carbon we emit, the less likely it becomes that the ice sheets will survive in the long term at anything close to their present volume."
A 2015 report from the National Academies of Sciences, Engineering, and Medicine illustrates the potentially devastating effects of ice-shelf melting in western Antarctica.
"As the oceans and atmosphere warm, melting of ice shelves in key areas around the edges of the Antarctic ice sheet could trigger a runaway collapse process known as Marine Ice Sheet Instability. If this were to occur, the collapse of the West Antarctic Ice Sheet (WAIS) could potentially contribute 2 to 4 meters (6.5 to 13 feet) of global sea level rise within just a few centuries."
