Rick Marken (2004.06.24.1520)--
Thanks for being clear about what you are up to and for demonstrating that
when it comes to confusion about science you have no peer.
Perhaps you can point out where I've made a mistake like Bill Powers
made when he posted his dad's claim that investment was a constant
(plus or minus 2 percent) proportion of income?
I can't point to anywhere that you have made a mistake because you never
make mistakes, at least according to you.
All I asked was "can you point out ? " this isn't quite the same as my
claiming that I have never made a mistake. Or, can you point out where
I mistakenly claimed that I never made a mistake? It seems to me that you
are making more mistakes, in first mistakenly reading what I have said,
and then without thinking, or rather mistakenly thinking, say stuff that
obvious mistaken.
This is probably your main confusion about science. Science isn't about
not making mistakes.
However, if you are frequently making mistates the science may not go
much of anywhere, or it may go into the ditch.
It's not about making infallible pronouncements.
So, was Bill Powers' claim that it wasn't going to cost anything to go
to Mars a pronouncment or not?
That's what religion is about.
Some people have the idea that religion is really about love.
Science is about carefully observing, industriously modeling and then
submitting one's observations and models (explanations) to public scrutiny
and correcting one's work if mistakes are discovered.
Bill Powers really could have been a bit less servere-- it wasn't kind for him, not me you understand, to have called your economic (not I am still not going to call it a model) program "a giant leap in the wrong direction.
Mistakes don't prove one to be non-scientific.
But you see I never made the mistake of thing anything of the kind.
They prove one to be human.
No, I don't think so. Say your dog poops on the carpet. That is a mistake, but it doesn't make your dog human.
Failure to admit or correct one's mistakes is non-scientific.
But, of course. However, the other side to this is that admitting or correcting mistakes is not neccesarily a contribution to science.
You offer the following statement by Bill Powers as evidence that he is
confused about science.
One interesting fact is that for the past 100 years, the expenditures
by the "composite producer" on capital costs - - i.e., investment - -
has remained constant at 20 2 percent of total income...
You then present the following data as evidence that capital investment has
not remained constant over the last 100 years:
Wally Peterson p. 49. _Income, Employment and Economic Growth_
reports these figures:
GNP GDI %1929 103.9 16.7 16.1
1933 56.0 1.6 2.9
1940 100.4 13.4 13.4
What you have done here is actually very scientific; you have presented data
that suggests that capital costs (GDI) have not remained constant over at
least 3 of the last 100 years. I'm sure that if Bill Powers could be
convinced
This is where the issue of subjectivity, solipcism and "All I can know is what I percieve comes into play. Science isn't about Bill Powers' convictions. We know what Bill Powers' convictions have been regarding TCP. I get blamed for pointing out errors and attacking Bill Powers' dad. Ordinarily people are going to understand that there is a difference between science and the sort of things that sometimes develop between fathers and sons. In the CSG program Bill Powers' dad's work is troted out, and suddenly there is somehow an assumed obligation to "contribute" to what many people would see in terms of father and son issues.
that at the GNI numbers presented above are the same as the GNI
numbers used by TCP to compute capital investment then he would agree that
TCP had made a mistake.
What happened ?
That's a good question. I think TCP used as his measure of capital
investment the difference between GNP and GNIncome, both of which can be
found as entries in the Statistical Index. That is, I think he calculated
GNI as GNP-GNIncome under the assumption that if GNP represented aggregate
expenditure (per year) and GNIncome represented the component of GNP
received as income (per year) by the aggregate consumer, then the difference
is aggregate capital investment. You may consider this way of computing
capital investment to be incorrect.
It isn't that the computation is incorrect, as it is, as I understand it, that Bill Powers' dad apparently claimed that the constancy of investment to income held for a hundred year period and didn't check the fluctionations generated by the boom, the bust, and the war to see if his claim genuinely held for the 100 year period.
If so, the scientific thing to do is to explain why it's incorrect and, thus, why Bill's statement about the
constancy of the rate of capital investment is wrong.
Scientifically I shouldn't have to explain "why" Bill Powers' dad made a mistake of not checking to see that these years didn't match his claim about the constancy of GDP and GDI.
It should be enough to show, not "why" but how it is that the claim is not correct.
ANd, Isn't that what I've done? I've found data, it took about five minutes.
What Bill Powers' dad should have done before claiming what he, and what Bill Powers might have done before he repeated his dad's claim was to compute the numbers for every year of the hundred years for which the claim was made. Bill Powers initially attempted to explain why his dad didn't present data for the years of the boom, the bust and the war moblization as being the result of data not having been collected for those years. This was, and is, an astonishing argument
The non-scientific thing to do is to treat Bill's statement as heresy and to act as though anything else Bill has >said or will say on the topic of economics is now and forevermore to be considered wrong.
It may be a bit of an exageration to accuse me of religious bigotry because I happened to notice that something that Bill Powers dad said about an economic relations was wrong. And, it was wrong.
I find it strange that you are mixing a discussion of the methodology of science and claims concerning heresy. There is a sense in which science is connected to skepticism and unbelief, rather than to belief, and the question of orthodoxy of belief. As to what attitude we should toward what Bill Powers has to say about economics-- I don't think it is going matter much. I hope at least that Bill Powers succeeds in developing a colaborative book on control theory. If such a project works out, and I hope that it does, then there is little likelyhood that he will be inclined to continue the test-bed project.
And, while I may sometimes be a bit confused, I haven't as yet, as
you have done, made mistakes in other people's papers.
What I did that was wrong was not that I made a mistake but that I took it
upon myself to add a sentence to your paper without getting your approval
first.
I think it's good that you recognize that you can sometimes be mistaken
(confused) yourself. I have found that when I accept my own fallibility I am
better able to improve my work through learning and forgive the mistakes of
others through empathy.
Rick this is I think a strange way of ending a sequences of posts that began with a claim that,
when it comes to confusion about science you have no peer.
I would say based on the evidence provided that Bill Powers' dad was a lot more confused than I have ever been in approaching economics in a scientific spirit. Lets not get side tracked into a discussion of self improvement, and forgiveness and lose sight of your factual claim-- that is,
when it comes to confusion about science [Bill Williams has] no peer.
Bill Powers' dad, Bill Powers and you made too many claims that were not based upon evidence. Bill Powers' dad never computed the numbers that he should have to support his claims.
when it comes to confusion about science [Bill Williams has] no peer.
I would say that when it comes to confusions concerning economics Bill Powers' dad, Bill Powers and Rick Marken have had comparatively very few peers.
Bill Powers and Rick Marken when they are disturbed have a persistent habit of saying things about me, such as Williams doesnt' understand anything, or he knows nothing, or this latest that as far as confusion, I am more confused than anyone about science. Nobody, it seems is more confused than Williams about science. This probably makes is hard to endure when I can show in a specific but crucial instance that I have been right and that they have been wrong.
It may be sometimes be difficult, even in science to arrive at a conclusive judgment concerning right and wrong. However, it is easier to see who it is that continues to work a given field and who goes elsewhere to find softer ground.
