Human Biology of Poverty Symposium

We just finished a symposium on “the human biology of poverty,” held at ISCTE-IUL in Lisbon, and sponsored by the The Society for the Study of Human Biology. It really was a great meeting, full of important research on the effects of various forms of deprivation on biology and health in different populations. The complete program can be found here.

Kindness and Regrets

Be excellent to each other.” – Bill and Ted (20th century philosophers)

 

From a commencement speech by George Saunders: 

“What I regret most in my life are failures of kindnessThose moments when another human being was there, in front of me, suffering, and I responded…sensibly.  Reservedly.  Mildly.”

Saunders then describes a memory from the seventh grade, when he did not defend the new girl in school who was teased for being different. Forty-two years later, he still thinks of her occasionally, and even though he was not personally cruel toward her, he regrets not going out of his way to extend her kindness. He then questions why kindness is often lacking, and he looks for prescriptions to make it more common.

The speech is a good one, and it stirred up some personal memories of instances when I could have used some kindness from someone. Sometimes it came; others it didn’t. There were also situations that called for me to be the one to extend kindness to someone else who needed it. Sometimes I stepped up, although probably not as consistently as I should have. Fear can be a powerful deterrent. Like Saunders, I regret those missed opportunities.

Of course, the opposite of kindness is cruelty, and I’m often distressed by the latest story of human callousness, where someone is belittled for not conforming to another’s standards. For those of us who are not Rhodes Scholar Olympians (which is to say, nearly everyone), we all fall short of socially constructed ideals in some way. Either we’re not attractive enough, or not stylish, athletic, or smart enough (or too smart). Too red. Too blue. Too promiscuous or too chaste. Too tall. Too short. Too neurally atypical. Or, we’re the ‘wrong’ weight, gender, race, sexuality, ethnicity, social class, or speak the wrong dialect. We can be incredibly creative at finding the holes in the armor to bring someone down.

For such an intensely social species, we often seem to go out of our way to make each other want to leave the group.

Inequality, Health Disparities, & Obesity

An October poll of 1,000 likely voters found that Americans are increasingly concerned about income inequality. When asked: “How Big a Problem is Income Inequality in the US?,” the majority (74%) replied that it was either a big problem or somewhat of a problem. Predictably, there were differences in opinion by political ideology, but a majority of liberals (94%), moderates (81%), and conservatives (55%) answered that inequality was at least somewhat problematic. However, as is true of many polls, it was not specified exactly what people found unsettling about it. I suppose there are many reasons that people might find increasing inequality (and climbing rates of poverty) to be troubling, but I wanted to focus here on inequality and health, particularly on obesity.

First, what do we mean by poverty? I remember watching an interview on PBS with the economist Jeffrey Sachs years ago (transcript here – thank you, Google), where he distinguished between two types of poverty. The first was an extreme form, which he called the type of “poverty that kills.” The other type was more of a poverty of inconvenience or jealousy. I don’t want to over-interpret Sachs’ meaning. It was a passing phrase in an interview from ten years ago, and his primary focus was on alleviating the extreme poverty faced by more than a billion people in the world living on $1 per day (see Sachs 2005). Elsewhere, Sachs has lamented that the media have ignored poverty in the United States at a time when “the U.S. has the greatest income inequality, highest per capita prison population and worst health conditions of all high-income countries.” His credentials in fighting poverty are unassailable. But I cite the old interview here because I think his descriptions (‘poverty that kills’ vs. ‘poverty of jealousy’) might resonate with many people today, and not necessarily in a good way.

Choice, Obesity & the Irrational Ape (Homo insensatus)

What I see in Nature is a magnificent structure that we can comprehend only very imperfectly, and that must fill a thinking person with a feeling of humility.

……………………………………………………………………………………. – Albert Einstein

Another irrational ape (imitating Rodin’s ‘The Thinker’)

Jonah Lehrer has written another great piece about our irrationality in decision making, and our emotional responses to avoiding loss. He writes:

From the perspective of economics, there is no good reason to weight gains and losses so differently. Opportunity costs (foregone gains) should be treated just like “out-of-pocket costs” (losses). But they aren’t – losses carry a particular emotional sting.”

Others have noted the importance of emotion involved in decision making, and how it affects our ability to intuit how our choices will make us feel. When someone suffers damage to the prefrontal cortex of their brain, both their emotions and decision-making abilities are impaired (Bechara et al 1997). What this suggests is that emotions and reason are linked, rather than oppositional. They inform each other. This all fits in with Dan Ariely’s view of humans as “predictably irrational.”

Inequality, Evolution & Obesity

A recent study on child obesity by researchers at Harvard has received a good deal of media attention lately. In the NY Times, a synopsis of the study was one of the most emailed articles in the country (“Baby Fat May Not Be So Cute After All,” March 22). The key sentence from that article:

“More and more evidence points to pivotal events very early in life — during the toddler years, infancy and even before birth, in the womb — that can set young children on an obesity trajectory that is hard to alter by the time they’re in kindergarten.”
