An interesting blog post by Razib Khan, who many here probably know from his Gene Expression blog, the old gnxp site or perhaps from his BHTV debate with Eliezer.
One point which I’ve made on this weblog several times is that on a whole range of issues and behaviors people simply follow the consensus of their self-identified group. This group conformity probably has deep evolutionary origins. It is often much cognitively “cheaper” to simply utilize a heuristic “do what my peers do” than reason from first principles. The “wisdom of the crowds” and “irrational herds” both arise from this dynamic, positive and negative manifestations. The interesting point is that from a proximate (game-theoretic rational actor) and ultimate (evolutionary fitness) perspective ditching reason is often quite reasonable (in fact, it may be the only feasible option if you want to “understand,” for example, celestial mechanics).
If you’re faced with a complex environment or set of issues “re-inventing the wheel” is often both laborious and impossible. Laborious because our individual general intelligence is simply not that sharp. Impossible because most of us are too stupid to do something like invent calculus. Many people can learn the rules for obtaining derivatives and integrals, but far fewer can come up with the fundamental theorem of calculus. Similarly, in the 18th century engineers who utilized Newtonian mechanics for practical purposes were not capable of coming up with Newtonian mechanics themselves. I’m using these two examples because calculus and mechanics are generally consider “high level” cognitive tasks, but even they at the root illustrate the principle of collective wisdom and group conformity. Calculus and mechanics is included in the curriculum not because all of the individuals who decide the curriculum understand these two topics in detail, but because individuals whom they trust and believe are worthy of emulation and deference, as well as past empirical history, tell them that this is the “reasonable” way to go. (science and engineering have the neat property is that you don’t just trust people, you trust concrete results!)This sort of behavior is even more evident in political and social viewpoints. Recently there have been signs of shifts in African American attitudes toward same-sex marriage, and a more general trend in that direction across the population. Is this because individuals are sitting in their armchair and reflecting on justice? Of course people will enter into evidence the experience of knowing gay people, and the empathy which that generates, but are you willing to bet that these public policy shifts are primarily and independent driven by simply these sorts of dynamics? (i.e., run a regression and trying predict the change in attitude by the number of people coming out of the closet over time) Similarly,people like Chris Mooney have documented the shift among the Republican grassroots in issues like climate change which seem to have moved very rapidly likely due to elite cues, rather than a deep analysis of the evidence.
But let’s look at something less controversial, at least on this weblog. Most people who accept evolution really don’t understand how it works, nor are they very conversant in the reasons for why evolutionary process is compelling. The vast majority of the 50 percent of Americans who accept evolution have not read Charles Darwin, nor could they tell you what the neo-Darwinian Synthesis is. They have not read Talk Origins, or Why Evolution is True. So why do they accept evolution? Because evolution, like Newtonian mechanics, is part of established science, and educated people tend to accept established science. But that’s conditional. If you look in the General Social Survey you notice a weird trend: the correlation between education and acceptance of evolution holds for those who are not Biblical literalists, but not for those who are Biblical literalists! Why? Because well educated Biblical literalists accept a different set of authorities on this issue. In their own knowledge ecology the “well-informed” perspective might actually be that evolution is a disputed area in science.
At this point everything is straightforward, more or less. But I want to push this further: most biologists do not understand evolution as a phenomenon, though they may be able to recall the basic evidence for evolution. If you are working in molecular biology, medical research, neuroscience, etc., there isn’t a deep need to understand evolutionary biology on a day to day basis on the bench (I would argue the rise of -omics is changing this some, but many labs have one or two -omics people to handle that aspect). The high rates of acceptance of evolution among researchers in these fields has less to do with reason, and more to do with the ecology of ideas which they inhabit. Evolutionary biologists in their own turn accept the basic structural outlines of how axons and dendrites are essential in the proper function of the brain without understanding all the details about action potentials and such. They assume that neuroscientists understand their domain.
So far I’ve been talking about opinions and beliefs that are held by contemporaries. The basic model is that you offload the task of reasoning about issues which you are not familiar with, or do not understand in detail, to the collective with which you identify, and give weight to specialists if they exist within that collective. I would submit that to some extent the same occurs across time as well. Why do we do X and not Y? Because in the past our collective unit did X, not Y. How persuasive this sort of argument is all things equal probably smokes out to some extent where you are on the conservative-liberal spectrum. Traditional conservatives argue that the past has wisdom through its organic evolution, and the trial and error of customs and traditions. This is a general tendency, applicable both to Confucius and Edmund Burke. Liberal utopians, whether Mozi or the partisans of the French Revolution, don’t put so much stock in the past, which they may perceive to be the font of injustice rather than wisdom. Instead, they rely on their reason in the here and now, more or less, to “solve” the problems which they believe are amenable to decomposition via their rational faculties.

I recommend following the link and reading the rest of it there, not only does interestingness continue, the comment section there is usually worth reading since he vigorously moderates it.
I mostly agree, that's all good and well... until it comes to moral choices, especially big ones. Here, even if people are very biased, don't know their own preferences, just plain don't care about others, etc... shallow conformism is still a worse option in many situations. If everyone just looked to their current group's authorities in deciding how or whether to do the right thing - and those authorities looked to the past - ... wouldn't we have, for example, 0% of Germans resisting the Holocaust instead of 2%? Wouldn't slavery be a respected institution to this day, lazily "justified" by things like genetic differences? Wouldn't, say, husbands be allowed by law and public opinion to beat, rape and essentially own their wives?
No, no, "conservative"/"traditionalist" ethics are a path to nowhere without a complex semi-conscious system, varying from individual to individual and acting on both rational and emotional levels, that would allow one to relate one's personality and preferences with their group's tradition and accumulated knowledge/heuristics, and which would be given priority during judgment-making by an appeal to a higher, ideal authority - in short, without an essentially religious worldview.[1]
Unfortunately, not everyone has it in them to be Oskar Schindler or Sophie Scholl, but many people only had to be "good Christians" when the moment of truth came - to follow the output of that deep and broad system, which had been known as "Christianity", "Western values", "common decency", but which ultimately drew upon similar sources, and had the ethical advice of centuries encapsuled within it. Alas, it was the 20th century, and things like that - old, complicated, below-the-surface systems - were just falling apart everywhere. But we shouldn't just sit back and allow our own system to follow this course.
This is why I'm against any "rational" tampering with today's mainstream Western worldview, even where I'm to the left or to the right of its political aspects. Any attack on "Liberal hypocrisy" that has indeed taken root in the last 50 years and largely replaced Christianity is short-sighted simply because this system is likely the only thing really holding our civilization together. If anything, perhaps we should move towards giving it more religious trappings - official commandments, saints, etc - without necessarily adding any supernatural element, but certainly without naively preaching that e.g. "Human Rights" don't make much sense.
Today, a thinking conservative should be focused on improving and stabilizing the prevailing liberal dogma, not trying to return to the failed Protestant/Catholic one or make a "dogma-free" system. In short, I'm for free individual search through the collected conscious and subconscious ideas of your culture - its narrative. And where you've got a narrative, you've got humans' natural ability to work with stories; abstract ideas are counter-intuitive, but picking out, combining and adapting stories is, IMO, how we can best handle social thinking.
(Sorry for such a rambling comment, I was just prompted to unload some under-construction ideas by seeing a post that's related to them. Paragraphs here can be read separately.)
[1] I'm not talking about any kind of "faith" here, a belief in the suprenatural and so forth, but about the style of thinking that organized religion or advanced ideology seems to foster in developed, all-around intelligent people - like Chesterton or Orwell. My argument is that the average human also benefits from such a system, and this would be more noticeable with better systems. (Compare the Socialism/Communism of the students and professors who were behind the dismantling of the Segregation in the U.S. - mostly good people, for all their flaws and possible delusions - with e.g. the primitive, simplified worldview of early Bolsheviks. Both are clearly religions, but one does its adherents more good than the other.)
Yeah, I suppose if you believe Christianity is/was the only thing holding civilization together, then adopting "Liberal hypocrisy" to fill the same role might make sense. Many people would disagree with the premise, though, by pointing to the Dark Ages and such. I don't really know what to think about this.
