(Press-News.org) Most of the time, we try to avoid inflicting pain on others — when we do hurt someone, we typically experience guilt, remorse, or other feelings of distress. But for some, cruelty can be pleasurable, even exciting. New research suggests that this kind of everyday sadism is real and more common than we might think.
Two studies led by psychological scientist Erin Buckels of the University of British Columbia revealed that people who score high on a measure of sadism seem to derive pleasure from behaviors that hurt others, and are even willing to expend extra effort to make someone else suffer.
The new findings are published in Psychological Science, a journal of the Association for Psychological Science.
"Some find it hard to reconcile sadism with the concept of 'normal' psychological functioning, but our findings show that sadistic tendencies among otherwise well-adjusted people must be acknowledged," says Buckels. "These people aren't necessarily serial killers or sexual deviants but they gain some emotional benefit in causing or simply observing others' suffering."
Based on their previous work on the "Dark Triad" of personality, Buckels and colleagues Delroy Paulhus of the University of British Columbia and Daniel Jones of the University of Texas El Paso surmised that sadism is a distinct aspect of personality that joins with three others — psychopathy, narcissism, and Machiavellianism — to form a "Dark Tetrad" of personality traits.
To test their hypothesis, they decided to examine everyday sadism under controlled laboratory conditions. They recruited 71 participants to take part in a study on "personality and tolerance for challenging jobs." Participants were asked to choose among several unpleasant tasks: killing bugs, helping the experimenter kill bugs, cleaning dirty toilets, or enduring pain from ice water.
Participants who chose bug killing were shown the bug-crunching machine: a modified coffee grinder that produced a distinct crunching sound so as to maximize the gruesomeness of the task. Nearby were cups containing live pill bugs, each cup labeled with the bug's name: Muffin, Ike, and Tootsie.
The participant's job was to drop the bugs into the machine, force down the cover, and "grind them up." The participants didn't know that a barrier actually prevented the bugs from being ground up and that no bugs were harmed in the experiment.
Of the 71 participants, 12.7% chose the pain-tolerance task, 33.8% chose the toilet-cleaning task, 26.8% chose to help kill bugs, and 26.8% chose to kill bugs.
Participants who chose bug killing had the highest scores on a scale measuring sadistic impulses, just as the researchers predicted. The more sadistic the participant was, the more likely he or she was to choose bug killing over the other options, even when their scores on Dark Triad measures, fear of bugs, and sensitivity to disgust were taken into account.
Participants with high levels of sadism who chose to kill bugs reported taking significantly greater pleasure in the task than those who chose another task, and their pleasure seemed to correlate with the number of bugs they killed, suggesting that sadistic behavior may hold some sort of reward value for those participants.
And a second study revealed that, of the participants who rated high on one of the "dark" personality traits, only sadists chose to intensify blasts of white noise directed at an innocent opponent when they realized the opponent wouldn't fight back. They were also the only ones willing to expend additional time and energy to be able to blast the innocent opponent with the noise.
Together, these results suggest that sadists possess an intrinsic motivation to inflict suffering on innocent others, even at a personal cost — a motivation that is absent from the other dark personality traits.
The researchers hope that these new findings will help to broaden people's view of sadism as an aspect of personality that manifests in everyday life, helping to dispel the notion that sadism is limited to sexual deviants and criminals.
Buckels and colleagues are continuing to investigate everyday sadism, including its role in online trolling behavior.
"Trolling culture is unique in that it explicitly celebrates sadistic pleasure, or 'lulz,'" says Buckels. "It is, perhaps, not surprising then that sadists gravitate toward those activities."
And they're also exploring vicarious forms of sadism, such as enjoying cruelty in movies, video games, and sports.
The researchers believe their findings have the potential to inform research and policy on domestic abuse, bullying, animal abuse, and cases of military and police brutality.
"It is such situations that sadistic individuals may exploit for personal pleasure," says Buckels. "Denying the dark side of personality will not help when managing people in these contexts."

Irritable bowel syndrome patients extensively suffer from chronic visceral hypersensitivity, with involvement of all levels of the brain-gut axis, as well as various neurotransmitters. Chronic visceral hypersensitivity can occur in the periphery, spinal cord and central nervous system, which has been shown to be the main pathophysiological mechanism underlying abdominal pain in patients with irritable bowel syndrome. Acupuncture at Tianshu (ST25) and Shangjuxu (ST37) has been reported to relieve visceral hypersensitivity for irritable bowel syndrome. Xinxin Guo and colleagues ...
The population of northeastern China has a high incidence of ischemic stroke. Previous studies have shown that intracranial large-artery atherosclerosis is one of the main causes of ischemic stroke, and that the mechanisms are related to inflammation and thrombosis of the affected arteries. A recent study by Lianqiu Min and colleagues from Liaoning Medical University observed the effects of atorvastatin treatment in 89 patients from northeastern China with acute ischemic stroke caused by intracranial large-artery atherosclerosis by measuring changes in the levels of markers ...
Astragaloside IV, the main component of the traditional Chinese medicine astragalus membra-naceus, has been shown to inhibit inflammation, oxidation, and apoptosis, and exerts immu-noregulatory effects. Xiaohong Zhang and colleagues from School of Pharmacutical Sciences, Jilin University investigated whether astragaloside IV could promote the repair of injured sciatic nerve. Denervated sciatic nerve of mice was subjected to anastomosis. The mice were intraperitoneally injected with 10, 5, 2.5 mg/kg astragaloside IV per day for 8 consecutive days. The researchers found that ...
Singapore, 11 September 2013 – By binding multiple molecules of a common leukemia drug with nanodiamonds, scientists from the National University of Singapore (NUS) and University of California, Los Angeles (UCLA) managed to boost the delivery of the drug to leukemic cells and retain the drug within the cells to combat the cancer.
This novel discovery, reported for the first time, addresses one of the major challenges in the treatment of leukemia where the cancer cells develop ways to pump drugs out of the body before they can do their job, particularly after they are ...
SYDNEY: A UNSW-led team of astronomers has begun to map the location of the most massive and mysterious objects in our galaxy – the giant gas clouds where new stars are born.
Using a telescope at Coonabarabran that narrowly escaped devastation in a recent bushfire, the team identifies the galactic clouds of molecular gas - which can be up to 100 light years across - from the carbon monoxide they contain.
"On Earth, carbon monoxide is poisonous – a silent killer. But in space, it is the second most abundant molecule and the easiest to see," says Professor Michael Burton, ...

Researchers at The Mount Sinai Medical Center have developed an innovative system to test how a virus interacts with cells in the body — to see, for example, what happens in lung cells when a deadly respiratory virus attacks them.
In the journal Cell Host & Microbe, investigators say such a technique will not only speed basic research into viral biology, it will also help scientists improve vaccine production, generate novel antiviral compounds, and advance the development of viruses that attack cancer cells.
"We have a powerful system in place today to investigate ...
CORAL GABLES, FL (September 9, 2013) — Recently, the global financial market experienced a series of computer glitches that abruptly brought operations to a halt. One reason for these "flash freezes" may be the sudden emergence of mobs of ultrafast robots, which trade on the global markets and operate at speeds beyond human capability, thus overwhelming the system. The appearance of this "ultrafast machine ecology" is documented in a new study published on September 11 in Nature Scientific Reports.
The findings suggest that for time scales less than one second, the financial ...
