　Moral compass

Led the study, MIT Department of Brain and Cognitive Sciences Liya Na Yang. She said to make moral judgments is a high act, "imposed in certain parts of the brain magnetic field, thus changing people's moral judgments, it is surprising."

Young referred to specific parts of the brain beneath the surface of the brain, behind the right ear. Professional name is "right-brain temporal skull connection." Consideration for this position to judge other people to do something in the psychological state of non-judgment, so have called it a "moral compass."

Researchers on the "moral compass" to impose transcranial magnetic stimulation, observed, "pointer" for changes. Transcranial magnetic stimulation is created 80s of last century a cortical stimulation, no pain, no damage, has been used in neurological, psychiatric and rehabilitation physiotherapy and other clinical treatment.



　　"Pointer" to deflect

The researchers recruited a group of volunteers, asking them to situations involving 192 acts of non-scoring. Scores increased from 1 minute to 7 points, 1 point that behavior "absolutely should be banned", 7 pm, said "absolutely."

In a situation in which a man knowing that there are security risks of a bridge, also over the bridge to his girlfriend, his girlfriend luckily without incident.

Under normal circumstances, most of the volunteers can not accept that men act. However, after receiving transcranial magnetic stimulation, the volunteers tend to accept his behavior.

Another scenario, two girls visit the chemical plant coffee, A to B to help in their own coffee and put some sugar. Labeled B from a "toxic" label to scoop out a bottle of white powder. A safe drinking coffee, because the sugar is indeed white powder.

Volunteers tend to transcranial magnetic stimulation is not based on a result of injury to allow B's behavior.

The overall test results showed that volunteers transcranial magnetic stimulation, to become able to accept the irresponsible or deliberately hurt others but do not result in harm.



　　More found

The researchers found that both the volunteers 25 minutes after transcranial magnetic stimulation to determine those situations in behavior, or while receiving magnetic stimulation to make judgments, judgments have changed.

"They get to accept those who do not attempt to harm harmful behavior, do not accept the results of those good intentions but bad behavior," Yang said.

She explained that people could not read magnetic stimulation may be motivation itself, so what the outcome will be based on other relevant information to make judgments.

The researchers said they want to further study the judge and jury to judge right and wrong. These two types of people often need to think about other people's mental state, for example, to do something because of acts of negligence or because the result does not think twice.
