TMS changes people's minds & morals


"You think of morality as being a really high-level behavior. To be able to apply (a magnetic field) to a specific brain region and change people's moral judgments is really astonishing."

Moral Judgments Can Be Altered: Neuroscientists Influence People’s Moral Judgments by Disrupting Specific Brain Region

ScienceDaily (Mar. 30, 2010) — MIT neuroscientists have shown they can influence people's moral judgments by disrupting a specific brain region -- a finding that helps reveal how the brain constructs morality.

To make moral judgments about other people, we often need to infer their intentions -- an ability known as "theory of mind." For example, if a hunter shoots his friend while on a hunting trip, we need to know what the hunter was thinking: Was he secretly jealous, or did he mistake his friend for a duck?

Previous studies have shown that a brain region known as the right temporo-parietal junction (TPJ) is highly active when we think about other people's intentions, thoughts and beliefs. In the new study, the researchers disrupted activity in the right TPJ by inducing a current in the brain using a magnetic field applied to the scalp. They found that the subjects' ability to make moral judgments that require an understanding of other people's intentions -- for example, a failed murder attempt -- was impaired.

The researchers, led by Rebecca Saxe, MIT assistant professor of brain and cognitive sciences, report their findings in the Proceedings of the National Academy of Sciences.

The study offers "striking evidence" that the right TPJ, located at the brain's surface above and behind the right ear, is critical for making moral judgments, says Liane Young, lead author of the paper. It's also startling, since under normal circumstances people are very confident and consistent in these kinds of moral judgments, says Young, a postdoctoral associate in MIT's Department of Brain and Cognitive Sciences.

"You think of morality as being a really high-level behavior," she says. "To be able to apply (a magnetic field) to a specific brain region and change people's moral judgments is really astonishing."

How they did it: The researchers used a non-invasive technique known as transcranial magnetic stimulation (TMS) to selectively interfere with brain activity in the right TPJ. A magnetic field applied to a small area of the skull creates weak electric currents that impede nearby brain cells' ability to fire normally, but the effect is only temporary.

In one experiment, volunteers were exposed to TMS for 25 minutes before taking a test in which they read a series of scenarios and made moral judgments of characters' actions on a scale of 1 (absolutely forbidden) to 7 (absolutely permissible).

In a second experiment, TMS was applied in 500-milisecond bursts at the moment when the subject was asked to make a moral judgment. For example, subjects were asked to judge how permissible it is for someone to let his girlfriend walk across a bridge he knows to be unsafe, even if she ends up making it across safely. In such cases, a judgment based solely on the outcome would hold the perpetrator morally blameless, even though it appears he intended to do harm.

In both experiments, the researchers found that when the right TPJ was disrupted, subjects were more likely to judge failed attempts to harm as morally permissible. Therefore, the researchers believe that TMS interfered with subjects' ability to interpret others' intentions, forcing them to rely more on outcome information to make their judgments.

Next steps: Young is now doing a study on the role of the right TPJ in judgments of people who are morally lucky or unlucky. For example, a drunk driver who hits and kills a pedestrian is unlucky, compared to an equally drunk driver who makes it home safely, but the unlucky homicidal driver tends to be judged more morally blameworthy.

I listened to some videos by Nick Begich, Jr, a professor, etcetera, and son of former Nick Begich, Sr, who was once a U.S. Congressman and, at another time, a Senator. Nick Begich, speaking of only the living son, has spent well over a decade, maybe close to two, researching the potential uses of EM, electro-magnetic, waves with respect to the uses for mind-control, both good and bad forms, as well as with respect to potential uses regarding our atmosphere and geology, like the potential ability to cause earthquakes. The videos are very informative and some videos with him interview him and other people with various scientifically related fields, say, of knowledge. I definitely recommend that people find these videos, which the Google Videos search engine can be used for, to minimally, but carefully consider what he says, for much of it is based on what he found in U.S. gov't documents that apparently anyone could see, read, just that few people have taken the time to do this.

In one or more of the mind-control videos, a Canadian doctor is interviewed in his clinic's or a hospital lab, where he practices MC using EM waves created with special technology. He uses it for good purposes, to help people.

www.ConsciousMediaNetwork.com did a three-part interview with Nick Begich and these can be accessed through the drop- or pull-down menu in the homepage near the top and on the left-hand-side of the page. One of the three parts is specifically or mostly about the EM waves through technology being usable for mind-control. But there are also enough videos at Google; just not any of those for the CMN interviews, which I guess are only found at that website.
