What’s in a Type?

One of my peeves against anti-evolutionists is those moderates who fully accept gene drift and mutations for short term changes (breeds, "micro-evolution") but not longer term changes (species, types, "macro-evolution"). Try to pin one of those people down on a definition of species and type, and one can always show them an observed example of something that crossed the line, or else multiple species that are obviously different but on the same side of their line. But this post is broader than that. For example, Pluto was a planet. Everyone knew that. Recently it was demoted to dwarf-planet. There are groups still dedicated to its reinstatement as a planet, like the Society for the Preservation of Pluto as a Planet. My presumption is, because that's what they were taught in their youth, therefore it's "As God Intended". Nothing changed in the sky, nor in our understanding of how things work. But a category changed and our world shook. Well, at least the world of those of us who noticed. What of moons? An excellent article is here: Meet our Second Moon! We now have two moons? And in my lifetime, the origin of our main moon changed from an unlikely captured or even less likely co-congealed object to a reasonable and most probably ejected one. I remember being disturbed when the moon count around Jupiter went from 12 (the 19th century standard) to 63 (care of Voyager etc). The count varies depending on how you define "moon". One has to be broadly accepting of both size and ballistic classification to accept 3753 Cruithne as a moon of the Earth, but it is there. Speaking of the moon, here is an incredible new way to see our moon up close (with pan and zoom) taken from ground based cameras. Things change. As I have mentioned many times on this blog, most people are hung up on the misconception that words accurately define things. The thinking that, if you have a name for it, then you understand the thing. You get the collector's fallacy: The confusion of the joy of matching names to things with the understanding of the things themselves. Knowing the names of thousands of birds (or bugs or species or stamps or diseases) and accurately matching them to the subjects is useful. But it is not complete in terms of understanding the similarities and differences. That is what is meant by the quote "Biology without evolution is but stamp collecting". One cannot understand things without also understanding the relationship between things (species, astronomical objects, populations, etc) and knowing the latest (most complete, so far) underlying set of theories (scientific definition, not vernacular). Humans are better than most other creatures at recognizing patterns. We regularly see patterns in random observations: Pareidolia. Any set of words will be an incomplete definition of any object. Defining a class of things is even more nebulous. Do species change over time? Certainly, given either enough time or a precise enough definition. How many moons are in the solar system? Good question. Define "moon", and show me the latest ballistic data on the 100,000 largest object so far discovered inside of the Oort Cloud. By the time I have an answer, something will have changed.

Longitudinal study tells us what makes people happy

What makes people happy? On quite a few occasions, I've posted at DI with regard to ideas that I learned through reading various books and articles (a search for "happiness" in the DI search box will give you dozens of articles). What does that reveal about me, I wonder? Today, I had the pleasure of reading an extraordinarily thoughtful article on this same topic: "What Makes Us Happy?" by Joshua Wolf Shenk appears in the June 2009 edition of The Atlantic. You'll find an abridged edition of the article here. Shenk's article is anchored by the Harvard Study of Adult Development, the longest running longitudinally study of mental and physical well-being in history. It was begun in 1937 in order to study "well-adjusted Harvard sophomores (all male), and it has followed its subject for more than 70 years." The study was originally known as "The Grant Study," in that it was originally funded by W.T. Grant. Despite all odds, the study has survived to this day--many of the subjects are now in their upper 80's. Along the way, the study was supplemented with a separate study launched in 1937 dedicated to studying juvenile delinquents in inner-city Boston (run by criminologists Sheldon and Eleanor Glueck). You'll enjoy Joshua Shenk's work on many levels. He writes with precision, providing you with a deep understanding of the featured longitudinal studies. You will also enjoy his seemingly effortless ability to spin engaging stories (there are dozens of stories within his article) and his exceptional skill at crafting highly readable prose. I'm writing this post as a dare, then. Go forth and read Shenk's article and I guarantee that you will be thoroughly enriched and appreciative. The Atlantic also provided a video interview of George Vaillant, now 74, who since 1967 has dedicated his career to running and analyzing the Grant Study. As you'll see from Shenk's article, Vaillant is an exceptional storyteller himself. The Atlantic article, then, might remind you of one of those Russian dolls, and that is a storyteller telling the story of another storyteller who tell stories of hundreds of other storytellers. For more than 40 years, Vaillant has not only gathered reams of technical data, but he has poured his energy into interviewing the subjects and their families and melding all of that data into compellingly detailed vignettes of the subjects. Telling stories is not ultimately what the study was supposed to be about, of course, and Vaillant also tells us what those stories mean for the rest of us. Truly, what makes people happy? Vaillant offers answers that you will be tempted to immediately apply to your own situation. Vaillant has a lot to say about "adaptations," how people respond to the challenges they face in life. As a Shenk explains,

I am judgmental

There's too many people out there actually get to know them all. While I'm walking down the street, or through a park or through a store, I pass by hundreds of faces and there is no way that I could possibly have enough time to get to know all of these people. In the grocery store, for example, I might pass four or five different people while walking around a single corner of an aisle. There's no time to get to know all these people and I find it impossible to walk past them without conjuring up an instant impression of who they are. Therefore, I am confessing that I am consciously and unremittingly judgmental. It's not that I categorize people by "race" or gender. That would be stupid, given that there's so many different kinds of people of every "race" or either gender. Nor do I judge people by what seems to be their social economic status. I know many people who work blue-collar jobs who are as smart as anyone I've ever met. I have friends who drive old cars when they could afford new cars. Or who wear unpretentious clothing by careful conscious design. I know people who walk, take public transportation or bicycle because they prefer to get around that way. I know people who shop frugally even though they could afford almost anything at all. I know people who are sharp as can be, even though they don't sound like it when they speak. Therefore, how is it that it is possible to be judgmental in good conscience?

The best way to have self-esteem is to have it

Can you get self-esteem by trying to convince yourself that you have it? Apparently not, according to a new study reported by the BBC:

Canadian researchers found those with low self-esteem actually felt worse after repeating positive statements about themselves.

They said phrases such as "I am a lovable person" only helped people with high self-esteem.

The study appears in the journal Psychological Science.

What we buy versus what makes us happy

Geoffrey Miller has just published a new book, Spent: Sex, Evolution and Consumer Behavior. I haven't read it yet, but I am now ordering it, based on Miller's terrific prior work (see here, for example). In the meantime, I did enjoy this NYT blog review of Spent, which includes this provocative question:

List the ten most expensive things (products, services or experiences) that you have ever paid for (including houses, cars, university degrees, marriage ceremonies, divorce settlements and taxes). Then, list the ten items that you have ever bought that gave you the most happiness. Count how many items appear on both lists.

If you're looking for simplistic answers, you won't get them from Miller. I won't spoil the answers he obtained or his analysis of those answers, but you'll find them here. [addendum] I found this one item refreshingly honest. Refreshingly, because I know a lot of parents, I see their faces, I hear their complaints (and their exhultations). I know that it's PC to say that having children is a continuous wonderful joy and that all parents are glad they did had children. Miller's research suggests that the answer is not this simple:

[Here's an answer that appears [much more on the ‘expensive’ than on the ‘happy’ lists [includes] Children, including child care, school fees, child support, fertility treatments. Costly, often disappointing, usually ungrateful. Yet, the whole point of life, from a Darwinian perspective. Parental instincts trump consumer pleasure-seeking.
