Magnetic field modifies morality

Click For Summary

Discussion Overview

The discussion revolves around the implications of a study suggesting that magnetic fields, specifically through Transcranial Magnetic Stimulation (TMS), may influence moral decision-making. Participants explore the relationship between brain function, morality, and the effects of TMS, with references to neurological studies and historical cases of brain injury.

Discussion Character

  • Exploratory
  • Debate/contested
  • Technical explanation

Main Points Raised

  • Some participants express skepticism about the validity of the study, with one stating it sounds "bogus."
  • Others argue that TMS is a legitimate technique that can alter brain function, suggesting that morality may be linked to neurological processes.
  • A participant questions whether the focus on moral questions after stimulating a specific brain area indicates a broader impact on cognitive processes.
  • Concerns are raised about the rigor of the assertions made in the study, particularly regarding the relationship between brain damage and moral behavior.
  • Some participants propose that morality may not be localized to a specific brain region but rather involves complex interactions across various brain areas, including the temporal and parietal lobes.
  • There is a discussion about the role of social intelligence and memory in shaping moral understanding, suggesting that morality is influenced by societal cues and experiences.
  • Several participants express disappointment with the media coverage of the study, criticizing it for sensationalism and lack of clarity.

Areas of Agreement / Disagreement

Participants do not reach a consensus; there are multiple competing views regarding the implications of the study and the nature of morality as it relates to brain function. Some agree on the potential of TMS to alter moral reasoning, while others remain skeptical about the conclusions drawn from the research.

Contextual Notes

Limitations in the discussion include the lack of access to the original study proceedings, which may hinder a full understanding of the research findings. Additionally, there are unresolved questions about the specific brain functions involved in moral reasoning and the implications of TMS on broader cognitive processes.

I found it and posted it above, thanks though Gokul, still appreciated.

Thanks to both!

I've just scanned the paper, but I'm disturbed by the small smaple size, and the nature of the test. I don't see ANY screening for morality vs. impulse and otheer diminshed capacity. It looks very interesting however, and somewhat startling. Putting what you believe to be poison in someone's coffee is DEEPLy anti-social, but it raises questions about perception that are not answered here.

I'd like to see something a bit more direct and screened, such as people rigging a card game, or even (fake) Russian Roulette. In other words, I want to see a clearly IMMORAL or amoral stance taken as a result of the TMS, not just abnormal behaviour after being blasted with a EM field targeted at a crucial region. Putting powder in coffee, as they admit in the paper, is not necessarily a clearly immoral act; it could be careless, or impulsive.

EDIT: More embarressing, I didn't notice that Pythagorean posted it. :redface: Oooooh boy. *raps on head... wooden sound fills room*.

It seems the connection between morality and the rtpj had been established already by other papers. See the references at the end. That's where you'll have to dig for the actual process involved.

I'm on my mobile now, but there were some complaints about the old view of the prefrontal lobe (I skimmed last night)

the descrepincy seems to be comparing negative outcome to negative intention.

I'll have to read more when I have time.
