A group of neuroscientists used functional magnetic resonance imaging to map the brain responses of swing voters as they looked at images and videos of the presidential candidates. Interesting stuff. But some of the responses were not in the least bit surprising:
When looking at pictures of Mr. Edwards, subjects who had rated him low on the thermometer scale showed activity in the insula, an area associated with disgust and other negative feelings. This suggests that swing voters’ negative emotions toward Mr. Edwards can be quite powerful.
I don't think we needed functional MRI to know that.
Life imitates the movies:
"When looking at pictures of Mr. Edwards, subjects who had rated him low on the thermometer scale showed activity in the insula, an area associated with disgust and other negative feelings." - article on scanner technology reading the brain
"Based on a Philip K. Dick short story, Minority Report is about a cop in the future working in a division of the police department that arrests killers before they commit the crimes courtesy of some future viewing technology." - review of 'Minority Report'
I read the whole thing, and I couldn't escape the whiff of bullshit.
This is another one of those studies where they study knee-jerk reactions. They can't possibly hope to assess people's reason over time, or measure how events or arguments could change their mental circuitry.
The initial observations themselves are kind of interesting, but an assumption that neuroscience is destiny is just the sort of psychobabble the Times loves to run, and not just on Sundays.
Neurobiology is not destiny. But it is developing into the science of measuring things we've always felt, but not had solid concepts for. We didn't know before whether one voter's digust was the same as another voter's disgust :) Now, we do. Sorta.

They may be scientists, but they sure aren't political scientists (not that I necessarily hold a lot of respect for college poli sci profs, but that's neither here nor there).
Generic Zocor Simvastatin drug is an hmg-coa reductase inhibitor or "statin" used to lower
bad cholesterol (LDL) and triglyceride levels in your blood or to raise good cholesterol (HDL) levels in adults.
Generic Lipitor ATORVASTATIN drug belongs to the group of medicines called
3-hydroxy-3-methylglutaryl coenzyme A (HMG-CoA) reductase inhibitors.It works by blocking an enzyme that is needed by the body to make cholesterol, thereby
reducing the amount of cholesterol in the blood.
Generic Crestor Rosuvastatin drug is used to reduce the amounts of LDL (bad) cholesterol,
total cholesterol, triglycerides (another type of fat), and apolipoprotein B (a protein needed to make cholesterol) in the blood. Rosuvastatin also increases
the level of HDL (good) cholesterol in the blood. These actions are important in reducing the risk of atherosclerosis (fatty deposits in the arteries), which
can lead to heart attack, stroke, and peripheral vascular disease.
Generic Norvasc Amlodipine drug is used to treat hypertension (high blood pressure) and
to treat angina (chest pain).
Generic Plavix Clopidogrel drug is used in the prevention and treatment of heart attack,
stroke, blood clots, and acute coronary syndrome.
