Could Electrically Stimulating Criminals' Brains Prevent Crime? (newatlas.com) 218

Posted by BeauHD from the factory-reset dept.
future guy shares a report from New Atlas: A new study by a team of international researchers from the University of Pennsylvania and Nanyang Technological University suggests that electrically stimulating the prefrontal cortex can reduce the desire to carry out violent antisocial acts by over 50 percent. The research, while undeniably compelling, raises a whole host of confronting ethical questions, not just over the feasibility of actually bringing this technology into our legal system, but whether we should?

The intriguing experiment took 81 healthy adults and split them into two groups. One group received transcranial direct-current stimulation (tDCS) on the dorsolateral prefrontal cortex for 20 minutes, while the other placebo group received just 30 seconds of current and then nothing for the remaining 19 minutes. Following the electrical stimulation all the participants were presented with two vignettes and asked to rate, from 0 to 10, how likely they would be to behave as the protagonist in the stories. One hypothetical scenario outlined a physical assault, while the other was about sexual assault. The results were fascinating, with participants receiving the tDCS reporting they would be between 47 and 70 percent less likely to carry out the violent acts compared to the blind placebo control.

    In a number of Larry Niven sci-fi novels, there are people addicted to brain stimulation, known as "wireheads".

    • I especially remember the story with Gil "Long Arm of the Law" Hamilton, and the wirehead that never bothered to leave his chair to eat, so he starved to death with a stupid grin on his face. That may well be a cautionary tale.

      • I recall that. It turned out that it was a murder; the murderer intentionally set the wire at an intensity well above safety limits and also spliced the power cord short. All the victim had to do to get to something to eat was unplug the wire (there was food right in the next room)--but he couldn't do it.

      ECT (electro-convulsive therapy) is used in the 21st century still, for severe depression that does not respond to therapy or medication.

      It can and frequently does have side effect of some degree of memory impairment (not "turn into vegetable") ... but that definitely is a better outcome than killing yourself.

    The sample is too small and too biased. The right way to test is to take ALL the inmates convicted of violent crime in jail. Divide them into two groups, and give them transcranial direct-current stimulation (tDCS) . Then watch their behavior. Once you prove definitively this things helps make peaceful society, we can extend this to the general population.

        The OP is 100% correct. Taking "normal" people, people who have not committed violent acts, DOES NOT tell you this procedure would stop someone who WOULD commit violent acts. Obviously there's a difference between someone who commits a violent act and someone who doesn't.

    • The sample is too small and too biased.

      How exactly is the sample biased? Generally speaking, if you're trying to prove an effect is real then you use a normal population; targeting specific populations happens later. The sample size is fine, as generally you can get significant results with 50-100 participants.

      Once you prove the effect, you can run more specific experiments later. E.g., a test on criminals to demonstrate whether the treatment is effective on that particular population.

      One notable limitation of this study is that there is no data

      • The sample is biased because they had crappy controls.

        • They had significantly more women than men in the overall sample (45 vs 36).
        • The control group ended up evenly split (21 vs 21) while the treatment group was ridiculously imbalanced (24 vs 15).

Also American society has so many ways to get tripped up by the system that the average person actually commits 3 felonies a day without really knowing that they've done so and these are basically law abiding people.

      True, but irrelevant.

      Even complex decisions can be changed by simple methods. Increasing the perceived "wrongness" of a violent act won't stop all violence, but it will stop some. If this is effective, then it makes sense to use it---even if cannot be 100% effective due to the underlying complexities.
