Fatalism and Ethics

By Dr. Richard G. Petty, M.D. | January 31st, 2008

We are constantly inundated by reports of the consequences of bad decision-making, and that leads us to consider two issues: genetic determinism - the notion that our behavior is totally the result of our genes - and whether or not we have free will. This is a hugely important issue, not only for each of us personally, but also for our views about morality and the justice system. And what happens when everyone becomes convinced that they have no free will and that “they’re genes made them do it?”

We know from our own experience as well as empirical studies that changing a person’s sense of responsibility can change his or her behavior.

Interestingly, the link between fatalistic beliefs and unethical behavior seems never to been examined scientifically.

In two recent experiments published in the journal Psychological Science psychologists Kathleen Vohs of the University of Minnesota and Jonathan Schooler of the University of British Columbia decided to see if otherwise honest people would cheat and lie if their beliefs in free will were manipulated.

They gave college students a mathematics exam. The math problems appeared on a computer screen, and the subjects were told that a computer glitch would cause the answers to appear on the screen as well. They were told that to prevent the answers from appearing, the students had to hit the space bar as soon as the problems appeared.

This was a ruse: the researchers were observing to see if the participants surreptitiously used the answers instead of solving the problems honestly on their own. Before the test they used a well-established method to prime the subjects’ beliefs regarding free will. Some of the students were told that science has disproven the notion of free will and that the illusion of free will was an artifact of brain activity. The other group where told nothing about free will.

The results were clear: those with weaker convictions about their power to control their own destiny were more likely to cheat when given the opportunity compared with those whose beliefs about controlling their own lives were left untouched.

The researchers then went a step further to see if they could get people to cheat with unmistakable intention and effort. The experimenters set up a different deception. This time they had the subjects take a very difficult cognitive test. Then they were asked to solve a series of problems without supervision and to score themselves. They also “rewarded” themselves $1 for each correct answer. To collect the cash they had to walk across the room and help themselves to money in a manila envelope.

The psychologists had previously primed the participants to have their beliefs in free will bolstered or reduced by having them read statements supporting a deterministic view of human behavior.

This study shows that those with a stronger belief in their own free will were less likely to steal money than were those with a weakened belief.

The results of this study indicate a significant value in believing that free will exists. The work also raises some significant questions about personal beliefs and personal behavior.

“The flame of Christian ethics is still our highest guide.”
–Sir Winston Churchill (English Statesman, British Prime Minister, 1940-1945 and 1951-1955, and, in 1953, Winner of the Nobel Prize in Literature, 1874-1965)

“You’re born with intelligence, but not with ethics.”
–Masad Ayoob (American Firearms and Self-defense Instructor and the Director of the Lethal Force Institute in Concord, New Hampshire, 1948-)

“Fatalism, whose solving word in all crises of behavior is “All striving is vain,” will never reign supreme, for the impulse to take life strivingly is indestructible in the race. Moral creeds which speak to that impulse will be widely successful in spite of inconsistency, vagueness, and shadowy determination of expectancy. Man needs a rule for his will, and will invent one if one be not given him.”
–William James (American Psychologist and Philosopher, 1842-1910)

“To live lightheartedly but not recklessly; to be gay without being boisterous; to be courageous without being bold; to show trust and cheerful resignation without fatalism -this is the art of living.”
Jean de La Fontaine

“Custom has furnished the only basis which ethics have ever had.”
–Joseph Wood Krutch (American Naturalist, Writer and Critic, 1893-1970)

Violence and Diet

By Dr. Richard G. Petty, M.D. | January 30th, 2008

We have talked before about the link between nutrition and violence.

The evidence has continued to mount and I was pleased to see that the Wellcome Trust is funding trials in three British prisons to investigate the link between nutrition and behavior. This is a placebo study that will examine which nutrients are most important and at what dosage.

Volunteers from three young offenders institutions housing male prisoners aged 16 to 21 will take nutritional supplements in addition to their normal choice of food to ensure they receive the necessary vitamins, minerals and essential fatty acids to meet daily guidelines. The investigators will monitor how levels of nutrients affect a range of behaviors including violence, drug-related offences and incidents of self-harm.

The new trials build on previous research published in the British Journal of Psychiatry that was conducted at the then maximum security Young Offenders Institution in Aylesbury, Buckinghamshire. That study was funded by Natural Justice, a research charity that investigates the social and physical causes of offending behavior. Nutritional supplements - 2 grams per day of the omega-3 fatty acids EPA and DHA for three months - were given to ensure that inmates’ diets reached recommended UK dietary standards. The researchers found that the prisoners who consumed the active nutrient capsule committed on average 26% fewer disciplinary offenses overall than those taking the placebo and 37% fewer violent offenses.

The most likely reason why supplements can have such a large effect is because the proper functioning of nerve cell membranes and signaling molecules depends upon adequate amounts of minerals, vitamins and essential fatty acids in the diet.

This is extremely important work. Clearly nutrition is not the only driver of violence but it has been wondered for a long time whether the industrialization of our diets has contributed to the enormous rise in violent crime between the 1950s and 1970s.

“Violence is the last resort of the incompetent.”
Isaac Asimov (Russian-born American Biochemist and Writer, 1920-1992)

“Blessings crown the head of the righteous, but violence overwhelms the mouth of the wicked.”
–The Bible (Proverbs 10:6)


“Peace cannot be achieved through violence, it can only be attained through understanding.”

–Ralph Waldo Emerson (American Poet and Essayist, 1803-1882)

Antioxidants May Raise Cancer Risk?

By Dr. Richard G. Petty, M.D. | January 29th, 2008

Regular readers will know that I have for some years now been raising a red flag the wholesale promotion of antioxidants.

The trouble is this: antioxidants are supposed to help rid us of some of the free radicals that have been implicated in a small number of diseases, and may also play a role in some of the physical aspects of aging. However, free radicals are also some of the major cancer killers in the body, so eradicating them – even if it were possible – hardly seems like a good idea.

According to an analysis of a dozen studies including more than 100,000 patients in the Mayo Clinic Proceedings taking antioxidant supplements do not reduce cancer risk.

In fact smokers who take beta carotene supplements could be increasing their risk of smoking-related cancer and death.

Different antioxidants have different effects, and their effects may also vary depending on the part of the body involved.

The researchers looked at 12 trials that compared antioxidant supplements with placebo on cancer incidence and mortality. Antioxidant supplements did not reduce the risk of cancer. When they looked separately at beta carotene, they found the nutrient actually increased cancer risk by 10 percent among smokers. There was also a trend toward a greater risk of dying from cancer with beta carotene supplementation.

Selenium supplements reduced cancer risk by 23 percent among men, the researchers found, but had no effect on women. While vitamin E had no anti-cancer effect overall, supplementation with the nutrient was tied to a 13 percent lower prostate cancer risk.

A large study looking at vitamin E supplementation for prostate cancer is currently underway. While future studies of beta carotene and vitamin E for cancer prevention are very unlikely to show effectiveness, it would be worth doing further studies on selenium.

The moral of the story: we should be going for a balanced diet and a balanced life in general rather than putting our hopes in an over-simplified nutritional message.
