But this is not what is done. Instead, journalists write, pretty much universally, about "the scientific method", which is supposed to be an iterative procedure made up of observation, hypothesising and testing. This raises two questions:
1) Why don't journalists instead write about the life or physical or social science method? I suppose this is one of the widespread misunderstandings about science. There is also a gross public misperception about the validity that can be to attribute to scientific results. It is true that some of these points are subject to disagreement among philosophers of science, but I think all would agree that the public notions, upheld by journalists, is lazy, naive and incorrect.
2) You could also say, Ok, so there are multiple approaches taken in the various scientific disciplines. But what is wrong with iterative application of observation, hypothesising and testing as a truth finding method? Well, I'd argue, this isn't a method at all. Instead it's a description. I.e., it is not an approach that can be set into operation to uncover the truth.
In case that is confusing, I'll make the point in another way. Let's say you are interviewing the manager of a sports team and you ask him what is his strategy for defeating another team. Suppose he were to answer: "My strategy is to outscore my opponent". This is not a strategy at all. It is merely a restatement of the victory condition.
I came to your article never having heard of circling before, and your first iteration at describing put me into the mind: "well, it's just another name for a party". But later you explained how the group gives explicit attention to feelings, especially feelings of the moment. This bring to mind and experience I would like to share with you.
I typically operate in a very masculine oriented environment and I've sometimes heard women complain they find the approaches taken, say, to reaching a decision, are unnatural for them. This worried me. I'm a man and I'm aware of the danger that as a member of the dominant group I might have uncritically accepted the standard approach as the only viable approach. But I didn't really understand the complaint until years later, upon finding myself in an all female environment. How different the woman's way of dealing with problems! Whereas the male approach is to present possible solutions, weighing their likely impact in terms of company objectives, the women hardly confronted the problem at all. Instead they spoke at great length about their feelings; then closed discussion (seemingly without resolution) by performing some joint activity reinforcing group solidarity.
At first, this feminine approach struck me as childish. But then, I began considering the drawbacks of the approach I had been used to. The masculine approach eschewed any discussion of personal feelings: possible solutions were supposed to be judged solely against the criteria of company objectives, although what really went on was a competition to disguise personal interests in the cover of company goals. At the end of the discussion some approach would be agreed upon. But, since the selection was determined by power, it was rarely the best either from either the company or personal standpoints. And, inevitably, there would be losers who, by the ethos of the group were forbidden from expressing their feelings. No thought at all was given to group solidarity, and the participants left the meeting bitter or intent on "getting even" next time.
So now, which of these two approaches is really the most childish?
The impression I get from your article of circling is that it is aimed at correcting some of the defects of what I have been calling the masculine approach to decision making. Not everyone needs this equally (my woman's group certainly didn't) but for some people, if they went into it with an open mind, could certainly benefit.
As for how a group can best reach business decisions, I see advantages in combining the two approaches. We need the rationality of what I've been calling the masculine approach, but (in the masculine environment) it should be up to the leader to explicitly adopt behaviours enforcing the notion that personal feelings are a legitimate concern for expression and consideration as part of the chosen solution.
Hmm. I suppose the NY Times could run a column on the ethics of open discussion of violating medical confidentiality. No?
Certainly this sequence can be continued. With each new meta-iteration we are further removed from the original issue but might hope to benefit (?) from the silence-equivalent effect of increased incomprehensibility.
the question I want to ask about is what is it about humans, culture and brains that allows for such high variance within the species, that isn't true about mice and chimps?
Some points to consider:
1. Has it been demonstrated that variations in intelligence is that much greater for humans than for mice or chimps? This may be true, but you didn't indicate any references.
Whereas I could imagine a test for chimp intelligence, and even timed maze experiments on mice, the concept of what we mean by intelligence becomes increasingly attenuated as we deal with ever simpler life forms; so that, at some point, and maybe even quite early, experts will begin disagreeing on what they are trying to measure.
2. Modern day humans have a big advantage not only over other animals, but also over our cognitively equivalent ancestors of 12+ thousand years ago. Thanks to the invention of culture, we pass knowledge to our offspring, meaning that knowledge can be accumulated from generation to generation. Variations in cognitive performance isn't only a consequence in variations in intelligence, but also reflects large differences in the quality of acculturation.
3. I wonder if your decision to compare interspecies variations in intelligence follows from a mistaken analogy. Consider, that intelligence is a human specialty. Other species have their own specialities. For instance, maybe we should be comparing variations in human intelligence with variations in the maximum speed of healthy, adult cheetahs. (I wonder, whether anyone has ever done this?)
4. The idea that we can assign a number to the variation in human intelligence is suspect. True, we can claim that the standard deviation in IQ is 15% of average IQ value. But it doesn't follow that a +1 sigma individual is 15% smarter than an average individual, because the IQ scale itself is arbitrary and intelligence has never been defined apart from performance on the test. To make the point in another way, 1-sigma variations in intelligence was arbitrarily set to 15 IQ points purely for convenience. We might just as well have set the mark at 900 IQ points. But that wouldn't mean that the +1-sigma individual was then ten times as intelligent as average.
Compare the situation with the cheetahs, where a statement like: "the ratio between the standard deviation in maximum running speeds and the average individual's maximum running speed is .15", really means something in terms of performance that can be measured with a metre and stopwatch.
What would be wanted to put IQ and maximum speed on par, would be credible results showing that a certain superiority in IQ is closely connected with a certain improved ability in raising fertile offspring to maturity, which is the definition of evolutionary success.
I think your idea about a Schelling point deserves further thought. But, why (and how) select the point arbitrarily? Why now presume that rational 100% Gandhi would perform an optimisation, according to his personal utility function, calculating the good the offered money could do against the harm done to the world by becoming less pacific?
Since you've already posited a third party, in your example, engaged to destroy Gandhi's prized possessions for deviations, why not just have Gandhi charge the man to shoot him as soon as he shows any sign of going on a murderous rampage? That sounds pretty 100%-Gandhi-like to me.
In fact, it is never hard to boost global utility by engaging an robot enforcer. The trick is to do without or, sometimes, to include the enforcer's own utility function (can he be subverted?) into the calculation!
I have the impression that Solomonoff Induction provides a precise procedure to a very narrow set of problems with little practical applicability elsewhere.
How would you use Solomonoff Induction to choose between the two alternative theories mentioned in the article: one based on Newton's Force Laws, the other based on the principle of least action. (Both theories have the same range of validity and produce the identical results).
I'm gratified to see my humble contribution receive attention, including from you. I'm learning. So thanks.
This is my first independent posting (I've commented before) and I didn't notice it appearing in the front page "latest posts". I understand you are a LW organisor. Can you help me understand the trigger criteria for an article to appear under "latest posts"? Thanks a lot! JH
It wasn't my purpose to open a discussion of interpretation of quantum mechanics. I only took this as an example.
My point is something else entirely: scientists have been leaning very heavily on William of Occam for a long while now. But try to pin down what they mean by a the relative complexity of an explanation, and they shrug their shoulders.
It's not even the case that scientists disagree on which metric to apply. (That would just be normal business!) But, as far as I know, no one has made a serious effort to define a metric. Maybe because they can't?
A very unscientific behaviour indeed!
Raemon, I understand your remark. But I've detected another problem. I've dropped the ball by posting my reply to the wrong remark. So, I'm going to have to do some cutting and pasting. Please bear with me.
The EY article really is super long (but interesting) and seems to go all over the place. I'd like to do habryka the courtesy of an answer reasonably promptly. I hope I'm not out of order by asking habryka for guidance about what is on his mind.
