Your mom always told you that it’s the thought that counts. And when it comes to pain, scientists appear to have shown that intentions really do matter. Harvard researchers report that people experience more pain if they perceive that the pain is intentionally inflicted.

“When someone steps on your toe on purpose, it seems to hurt more than when the person does the same thing unintentionally. The physical parameters of the harm may not differ—your toe is flattened in both cases—but the psychological experience of pain is changed nonetheless,” the researchers report in Psychological Science [pdf].

The researchers enrolled 43 participants in a study in which they were each paired with partner. Little did they know that the partner was actually a researcher running the study. The participant was hooked up to a machine and told that the partner, located in a separate room, would control whether or not to deliver an electric shock through the machine. In some cases, however, the partner’s choice would be reversed by the machine. The participant could see what the partner had chosen—shock or no shock—and whether the machine would follow the choice or reverse it. Even though the participants always knew they were about to be shocked, they rated the intentional shocks as more painful than the unintentional ones—3.62 versus 3.00 on a 7-point scale.

Pharmaceutical companies, make room for this news: Art can be used as a painkiller too.

As research shows, music helps ease emotional pain, and at the very least, it helps us relax. In a recent Italian study, researchers found that visual art can help ease physical pain.

Researchers in Italy asked twelve men and women to judge 300 pieces of art, and rate it as ugly or beautiful. While the participants judged the art’s aesthetics, the researchers zapped them with a laser pulse.

While tales of patients murdering their medical care providers are very real and very tragic, they’re also rare. But a disturbing new study indicates that thoughts of killing doctors occur more frequently than we might think, particularly among patients who are in pain, undergoing physical rehabilitation, or seeking compensation for a disability.

New Scientist reports that psychiatrist David Fishbain and his colleagues at the University of Miami, Florida, surveyed around 800 physical rehabilitation patients and found that just over 1 in 20, or around 5 percent, admitted that they entertained thoughts of murdering their physician. In a control group of people not in treatment for any condition, around 2 percent reported having felt the desire to kill their doctor in the past.
