Psychopaths Do Feel Regret – But Only After They’ve Crossed the Line, Harvard Study Shows
They have the same feelings as normal people. It’s how they make decisions that’s different.
Utter the word psychopath and immediately ideas of a sadistic serial killer with a penchant for blood comes to mind. Would it surprise you to know that you may interact with one every day? In fact, psychologists have noted that some of the top CEOs and others who hold lofty positions, and even many regular people who do not, have this condition. You may know, love, or even be a psychopath and not even know it. The important thing here is to define what a psychopath is.
The traditional definition is someone who cannot empathize with others, and so does not feel shame or regret for negative actions towards them. Fans of the TV series Dexter recognize this as the internal struggle of the main character. Their inability to understand the emotions of others makes them antisocial, which could cause the psychopath to become more of a threat in the boardroom, on the sports field, or in a dark alley, to others.
But now a new study is altering the definition entirely. Harvard associate psychology professor Joshua Buckhotlz was its co-author. He and Arielle Baskin-Sommers of Yale University found that psychopaths aren’t immune to empathy. Many do in fact feel regret when they hurt others.
What they cannot do is predict the outcomes of their choices or behavior. They somehow aren’t in tune with social norms, those rules that keep the peace and act as a social glue, thereby maintaining the social order. It is this inability to predict outcomes that may lead to them to poor choices, viewed as improper or even ghastly by others.
Some psychopaths may have their heart in the right place. But they can’t recognize when they’ve crossed the line.
Researchers recruited a number of incarcerated persons, some who were deemed psychopaths and others who were not, and had them play a game based on economics. A metric called prospective regret sensitivity was used to measure each participant’s level of regret, based on decisions they had made during the game. Psychopaths were seen as making riskier moves, but had difficulty evaluating whether or not they would regret them afterward.
Though we think of it as one emotion, Buckholtz claims that regret is actually a two-part process. The first part is retrospective regret. This is the kind we ruminate over, from the past. We think about a painful experience and wish we had made a better choice. From there, we can vow to take a different path in the future.
The second is prospective regret, which is when we take information from the environment and make predictions on what will happen, and whether or not we will regret our choice. Buckhotlz and Baskin-Sommers showed that it was an inability to make decisions based on values and understand the probable outcome, and its impact on others that defines a psychopath. “It’s almost like a blindness to future regret,” Buckhotlz said. Though in the aftermath they feel remorse, they can’t see it coming.
A large number of the incarcerated have psychopathic tendencies. This study may lead to retraining them to avoid poor decision making.
“Contrary to what you would expect based on these basic emotional-deficit models, their emotional responses to regret didn’t predict incarceration.” Buckhotlz said. Yet, “We know psychopathy is one of the biggest predictors of criminal behavior.” Being able to train individuals to recognize signs of future regret could be a way to make a more compassionate psychopath, and one that might stay away from trouble, and incarceration.
Though we know much about the condition, we know very little about how psychopaths make decisions, researchers said. Psychologists have mostly delved into how their emotions work and what emotional experiences they have. But how they use that information and other signals from the environment to make decisions, has heretofore, never been studied. According to Buckhotlz, “Getting better insight into why psychopaths make such terrible choices, I think, is going to be very important for the next generation of psychopathy research.”
Baskin-Sommers added further insight saying, “These findings highlight that psychopathic individuals are not simply incapable of regret [or other emotions], but that there is a more nuanced dysfunction that gets in the way of their adaptive functioning.” Understanding this can help psychologists develop better methods for predicting psychopathic behavior and perhaps even train such individuals to recognize clues and steer clear of pitfalls, thus making better life decisions.

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."
