Re: Economics of "Saving Agriculture" (Thereby Saving the World)

Dave, you have totally faceplanted here.
You posted a link to that paper by Price, saying you thought it was "very good science" and asking me what I thought. I read it carefully (in fact I read TWO papers carefully, because I am a fairly concientious person, and you'd given me a link to the wrong paper first time), and in both cases, spent some time writing my commentary.
You ignored all but ONE of my comments on the Price paper, and for that comment had a total tantrum because I said that the first figure was misleading junk. I explained why. You were perfectly entitled to query my evaluation "junk" but you actually agreed with the substance which was that the figure doesn't actually tell you anything. So not "good science" and certainly not "very good science" there.
The rest of my commentary you totally ignored.
When asked why YOU thought it was "good science" you posted this:
So Dave, tell us why you think it is "very good science".
What are the features or points in the paper that in your view make it "very good science"?
Lots of reasons ...
1) got out of his ivory tower and got his hands dirty trekking the globe collecting actual data
2) used controls
3) explained his hypothesis clearly - that it's not "cleanliness" or anything else ... it's NUTRITION that controls caries
4) figured out the exact mechanism of control ... calcium, phosphorus in the saliva etc
5) figured out the role of Vitamins A and D in helping the body use these minerals
On and on
To which I responded with these questions to you:

What are the features or points in the paper that in your view make it "very good science"?
Lots of reasons ...
1) got out of his ivory tower and got his hands dirty trekking the globe collecting actual data
I sometimes wonder where you think any scientist gets her data. But sure, he did a lot of travelling to get it. Cool. Doesn't make it "very good science" though. You can do "very good science" sitting at the top of your ivory tower with a telescope, like Galileo.
2) used controls
Please show me the part where he used "controls" and how he used them.
3) explained his hypothesis clearly - that it's not "cleanliness" or anything else ... it's NUTRITION that controls caries
Yes, he explained his hypothesis. Again, that doesn't make it good science. But it's good to know that his hypothesis was that NUTRITION controls caries, and not anything else.
4) figured out the exact mechanism of control ... calcium, phosphorus in the saliva etc
What evidence does he give to support his hypothesis that NUTRITION and ONLY nutrition controls dental caries?
What evidence does he give to support this hypotheses that it does so by means of these minerals to control dental caries?
5) figured out the role of Vitamins A and D in helping the body use these minerals
What evidence does he give to support this hypotheses regarding the role of Vitamins A and D in helping the body use these minerals to control dental caries?
On and on
So where is the evidence to support his hypotheses, Dave? Please give the page where he gives the data to support each his hypotheses:
- That NUTRITION and ONLY NUTRITION controls dental caries
- That NUTRITION controls dental caries by means of minerals in the saliva
- That NUTRITION controls minerals in the saliva through the action of vitamins A and D.
Apparently realising that you had no answers to them (you laughably pointed to Price's metaphorical use of the word "control" in his introductory sentence about the natural experiment of "civilisation", but could not produce any evidence that Price had actually "used controls" in the paper), you then backpedalled with this:
Price's hypothesis is simple ...
Town food causes bad teeth.
His paper gives ample support for this.
QED
If you can't see it you're blind.
Which of course nobody has disputed. Even though his paper does NOT actually support it - he provides NO evidence in that paper, other than mere assertion, illustrated by a figure showing what the data would look like if this hypothesis were true, not data that would actually support the hypothesis.
Then you bailed.
Then it was back to insults.
Pathetic.
I have a Darwin-debased mind.
