I'm More Free Than You Are

Everyone thinks everyone else has less free will

"Social psychologist Emily Pronin at Princeton University in New Jersey studies the differences between how we perceive ourselves and how we perceive others. According to her research, we tend to view our own judgment as sound but the judgment of others as irrational; recognize the biases in others but not ourselves; and see ourselves as more individualistic and others as more conformist."

Yes, hard to disagree with that...but quantitative evidence is nice to have I guess. Also, the concept of free will in the study seems a little confused. But then, if people are mostly confused about free will in the same way, then it probably doesn't matter in terms of interpreting the results.

Making Wise Choices About Environmental Goods

In my environmental philosophy class, this week we discussed preference utilitarianism, cost-benefit analysis, and whether we should trust people's stated preferences about how highly they value environmental goods.

I tend to be skeptical about economists' measurements of preference, though I don't know of a better and simpler tool that can be substituted.

Preferences can be discovered (only) by introspection, so it seems illogical to say that someone could be mistaken about what they prefer. The claim that someone can be mistaken rests on several observations:
1. Sometimes our actions do not follow our expressed beliefs. Which is the real preference: how we act or what we say?
2. People change their minds depending on how a choice is presented.
3. What we think will make us happy does not always, in fact, make us happy. Predictions of future happiness and unhappiness are wrong in systematic ways.

We talked about some of the mistakes that people make in estimating the value of their preferences and watched this video, from 6:00 to 12:54. I think Leroy's lottery ticket fallacy is particularly telling.

W.V.O. Quine Video

Here is part of a 1977 video of W.V.O. Quine being interviewed by Brian Magee on BBC TV.



Magee introduces Quine as "a philosopher at the very summit of world reputation."

In this clip, Quine talks about how philosophy is on a continuum with science but is also different from it. He gives the examples of history and engineering as being at the most applied end of the sciences and philosophy and mathematics being at the most abstract end.

Magee asks Quine about the sorts of questions that philosophy takes up. Quine says that the question of how the world began is for physicists to deal with. The question of how life began is a question for biologists. And the question of why the world or life began is not a question at all, not even one for philosophers. It's merely a pseudo-question, because it doesn't have an answer.

Finally, Quine divides philosophy into two categories--ontology and epistemology. Philosophy deals with questions about what there is and questions about what we can know. On the subject of what there is, Quine says that objects are either material or mathematical.

Well, I'm an undisputed fan of Quine (see this website)--but doesn't this seem like a narrow view of philosophy?

More gender exclusion

Since looking at the figures for women's unequal participation in philosophy and realizing that they haven't improved in two decades, I've been noticing places where women's participation is even less than the 20% that is typical for the field. And I've been wondering why this doesn't strike many of my colleagues as odd and even indefensible in the 21st century.

Today I got a flyer in my mailbox for the journal PHILO, which is the journal of The Society for Humanist Philosophers and is published by the Center for Inquiry in Amherst (Buffalo-area), NY. Although I was unaware of the journal, I am immediately favorably disposed to a journal that "examines philosophical issues from an explicitly naturalist perspective," since naturalism is a central commitment of this blog's contributors.

But I was shocked to glance over the editorial board and to see that out of 39 philosophers, only 3 are women! Surely more than 7.5% of naturalists are women! This ratio of men to women continues when I look at the contributors to the journal. It is typical that an issue will publish work by about 8 authors, all of them men.

What is the explanation? Is this just how social networks work? Are women in philosophy concentrated in some disciplines--and not in naturalist epistemology? Are women less represented on editorial boards in general?

I'm surprised, too, because the people that I know on this particular editorial board are open-hearted and fair-minded pragmatists, supportive of their women colleagues. One of them, Peter Hare, just passed away in the last week, and I will remember him with fondness. Memorials have been written here and here.

What’s natural about natural childbirth?

Jender at Feminist Philosophers has a recent post about natural childbirth. She writes that the literature supporting natural childbirth is too often misleading.
Telling women that if they shop around hard enough for the right midwife, and work hard enough on their relaxation techniques and positions they’ll have a great uncomplicated time is SERIOUS misinformation.

She raises an issue similar to my post earlier this week, where I argued that a general preference for ‘natural’ ecosystems over ‘improved’ or ‘disturbed’ landscapes can be justified empirically but not with metaphysics.

‘Natural’ childbirth can mean many things to different people, from vaginal birth, to a birth without pain medications, to a birth that minimizes interventions, to a home or unassisted birth. Sometimes--perhaps too often, as Jender notes--there is a belief that if labor and birth are allowed to progress in their own time and their own way, then the labor will be less painful and delivery will be uncomplicated. And then, when the labor and delivery are slow or complications do develop, a mother whose goal is natural childbirth could feel disappointed, cheated, or even ashamed, as though she was unable to achieve what “should” be a natural biological function.

But this view entails attaching a prescriptive metaphysics to the concept of ‘natural.’ It is analogous to saying that wilderness should be valued more highly than agricultural fields because wilderness is ‘natural.’ But I like to eat bread and grapes and artichokes! Still, without buying into a flat-rate preference for natural landscapes over cultivated ones, I think we can still justify on empirical grounds why we should look to what is natural to identify the conditions in which humans and other creatures flourish.

Likewise, empirical evidence and some well-accepted criteria for healthful outcomes are what is needed to support natural childbirth and, most importantly, to support educating expectant mothers about the physiological process of birth. A good education would include what sort of pain can be expected and the average duration of active labor (which, for first-time mothers, is 20 hours, more than many practitioners allow before augmenting with pitocin).

When C-section rates rise, so do mortality rates for mothers. Mothers who have had C-sections are more likely to have additional complications, take longer to recover (on average, of course), and are less likely to breastfeed. In addition, they are more likely to have complications with subsequent pregnancies. Other interventions, such as pitocin induction, epidural pain-relief, and electronic fetal monitoring are implicated in poorer outcomes insofar as they contribute to the likelihood of unplanned caesarean birth.

The evidence supports taking steps that are likely to give women more control over birth, more autonomy during labor, and more choice than is usual in US maternity wards. But intending a natural childbirth is certainly no guarantee that labor will progress according to a plan! It would be heartless to deny the necessity and high value of medical interventions when needed, not just for emergencies like placental abruption, but also for pain relief when unexpected pain is harming a mother’s ability to give birth.

Rixa has written recently on what should be done about rising caesaraean rates. She quotes Michael Odent:
The primary objective should not be to reduce the rates of caesareans: it would be dangerous, if not preceded by a first step. This first step should be an attempt to promote a better understanding of birth physiology and particularly a better understanding of the basic needs of women in labour.

A preference for what is natural

So often in what I read and in conversations with students about environmental problems, there is an implicit assumption that what is “natural” is better than whatever has been “disturbed” or “improved” by humans.

Most of the time, I feel that my task is to demand that the speaker think more critically about
1. why we should prefer a natural to an unnatural state since, for example, a world without smallpox seems to be a better world overall;
and
2. whether we can really ever identify a “natural” state, after millennia of human disturbance in most tropical and temperate regions and with the propagated effects of climate change, pollution, and transported species reaching even into apparent wilderness regions.

But to be fair, the shorthand of preferring natural conditions to unnatural ones is very often legitimate. Whether our concern is for human well-being or stability in ecosystems, the natural state is one that has been tested and proved, and the unnatural one has not. The proper justification, then, for this preference for what is natural is empirical evidence, not metaphysics.

Critics of the popular desire for political action on global warming like to point out that there are plenty of people who stand to be better off should their climate grow a little warmer. It will be possible to grow more wheat in Canada, for instance, and the Northwest Passage will become a viable alternative to shipping goods overland or through the Panama Canal. While it’s true that human changes may improve the world for some human goals, the fear is that they will disturb delicate systems with uncertain, and probably unwelcome, results.

A recent report in Science (Araki, Cooper, and Blouin, “Genetic Effects of Captive Breeding Cause a Rapid, Cumulative Fitness Decline in the Wild”, Science 318: 100-103) adds another case to the roster of well-intended interventions with negative long-term implications. It seems that captive breeding and wild release of fish stock may lead to lower reproductive fitness in only a few generations.

The report concludes
The evolutionary mechanism causing the fitness decline remains unknown. We suspect that unintentional domestication selection and relaxation of natural selection, due to artificially modified and well-protected rearing environments for hatchery fish, are probably occurring…To supplement declining wild populations, therefore, repeat use of captive-reared organisms for reproduction of captive-reared progenies should be carefully reconsidered.

This indicates that the study species--steelhead trout--are being domesticated. The alternative to stocking wild populations is to do more (much more) to prevent decline in the first place. This means reducing how many are taken and/or preventing habitat destruction. Neither is easy or popular.
