Measuring subjective happiness

In the January 29, 2010 issue of Science (available online only to subscribers), Richard Layard considers whether subjective reports are valid ways of measuring the well-being of a population. After all, we've been hearing some rather extraordinary findings of studies over the years based upon subjective happiness. For instance, studies consistently show that higher national income does not increase "quality of life," (defined by subjective happiness). In fact, based on studies relying on subjective judgment, there has been no increase in happiness over the past 50 years in the United States. Layard asks a fundamental question: "Can subjective well-being really be measured well enough to be used in policy analyses?" Even though the science of measuring happiness is "very young," Layard indicates that subjective measures of happiness are well correlated with at least five relevant sets of variables:

The reports of friends; the possible causes of well-being; some possible effects of well-being; physical functioning, such as levels of cortisol; and measures of brain activity.

There is good reason to be optimistic that we will get better at measuring happiness. "Fifty years ago, there was considerable debate on how to measure depression, but by now this has become much less controversial in all likelihood, the measurement of happiness will become similarly less controversial." As we fine-tune our methods of measuring of subjective happiness, Layard believes we will be better able to monitor trends of happiness, we will deal to identify problem groups within populations and we will be better able to determine why some people are happy and others are not. Better measurements will certainly allow us determine quality of life better than the many efforts to do so in terms of money. What's at stake according to Layard? As we leave behind our crude financial measurements of the quality of life and continue to develop better methods of measuring subjective happiness, "it will produce very different priorities for our society."

Richard Nisbett: Intelligence mostly varies due to the environment, not genes

The dominant hereditarian view of intelligence holds that intelligence is mostly fixed by the genes. Richard Nisbett has dismantled the evidence on which the hereditarian theory is based. In his new book, Intelligence and How to Get It, Nesbitt argues that the twin studies on which the hereditarian view is based are deeply flawed. The main problem is that the adoptive homes in which those separated twins often find themselves are uniformly enriched learning environments. Nisbett's book was reviewed by Jim Holt of the NYT Book Review:

Nisbett bridles at the hereditarian claim that I.Q. is 75 to 85 percent heritable; the real figure, he thinks, is less than 50 percent. Estimates come from comparing the I.Q.’s of blood relatives — identical twins, fraternal twins, siblings — growing up in different adoptive families. But there is a snare here. As Nisbett observes, “adoptive families, like Tolstoy’s happy families, are all alike.” Not only are they more affluent than average, they also tend to give children lots of cognitive stimulation. Thus data from them yield erroneously high estimates of I.Q. heritability. (Think: if we all grew up in exactly the same environment, I.Q. differences would appear to be 100 percent genetic.) This underscores an important point: there is no fixed value for heritability. The notion makes sense only relative to a population. Heritability of I.Q. is higher for upper-class families than for lower-class families, because lower-class families provide a wider range of cognitive environments, from terrible to pretty good.

What does Nisbett's book have to say about race and intelligence? That the differences among the "races" are not genetic. Evidence in point: The "racial" IQ gap has been shrinking. "Over the last 30 years, the measured I.Q. difference between black and white 12-year-olds has dropped from 15 points to 9.5 points."

The incessant allure of Republican morality and what Democrats can do about it.

For the past few years, moral psychologist Jonathan Haidt has successfully injected a huge does of psychology into the study of morality. Along the way, he has gone a long way toward bridging the “is” with the “ought,” a chasm that many philosophers have insisted to be unbridgeable.  Haidt explores these moral-psychological issues in highly readable form in his 2006 book, The Happiness Hypothesis:  Finding Modern Truth in Ancient Wisdom. Here’s a photo of my personal well-worn copy of Haidt’s book:

Based on his experiments, Haidt has been extraordinarily successful in describing the moral differences distinguishing conservatives and liberals.  Which group is more moral?  That isn’t the right question, according to Haidt.  Both of these groups sincerely strive to be “moral.”  Conservatives and liberals differ in the way they characterize morality because they base their differing moral senses on different measures. Based on Haidt’s research, there are the five separate measures (I think of them as tectonic plates) that underlie all moral systems.  Conservative morality substantially draws on all five of these five measures:

– harm/care
– fairness/reciprocity
– ingroup/loyalty
– authority/respect, and
– purity/sanctity

For liberals, however, the moral domain consists primarily (or only) of the first two of these five measures (harm/care and fairness/reciprocity).  For liberals, the other three measures (I’ll call them “conservative measures”) tend to fly under the liberal radar.  In fact, many liberals scoff at claims that the conservative measures (ingroup/loyalty, authority/respect and purity/sanctity) have anything at all to do with morality.  To avoid a …

Question the significance of the “gross domestic product” (GDP)

I just finished reading a terrifically clear and concise article on measuring "the economy" by Jonathan Rowe, published by Harpers. It is entitled "Our Phony Economy." Please allow me to set the scene. Haven't you wondered why politicians and the news media so often obsess about the rising and falling…
