So you think that someone who is **NOT** writing about his area of expertise shouldn't have credibility?
Nope didn't say that. But when someone points out that they have been a professor at Princeton for 30 years they should try not to embarrass their Alma mater by making 4th grade math errors. They shouldn't try to plot 3 independent variables on a 2 dimensional graph. He lost all credibility on anything to do with mathematics there. Perhaps I was more critical then I could have been, but if someone misrepresents data when common sense should have caught the error I think less of them. Pardon my crassness.
You're saying a geology professor has no business taking about economics, right? Is that the gest of your perspective?
I wasn't even critical of his economic conclusion of $300/bbl oil other then to state that I doubt it meant "smouldering ruins" and the fact that he wasn't sharp enough to recognize that GDP changes over time. If he can't demonstrate that level of cursory knowledge then he should stick to non-economic endeavors.
That was the gist of my argument. His presentation of the data was utter nonsense. In fact I am more concerned about his knowledge of geology. He sites econ 101 to state that supply goes up when prices do. If his geology background was strong enough, he would realize that it take time to discover and develop new fields. He would also have a general idea at what price points these activities would start to occur considering the difficulty of reaching the remaining oil. Having a few data points over the last couple of years showing volume has not increased would not lead him to conclude that we have reached peak oil. It doesn't prove anything. It would be only be one possibility. My opinion is that we will see a small increase in production before we hit peak, but I'm not a geology professor or an econ prof.
If so, then I assume you'd also be critical of engineers talking about literature or, ahm, economics professors talking about geology? Would that be fair?
Certainly it would be fair. If an engineer wants to have layman conversation about Hamlet with me I see no problem. But if he holds himself out to be an expert in Shakespearean literature and says "there is something rotten in the state of Scotland" I will certainly be willing to call foul.
And if it is, then I assume you take this same level of criticalality to people such as, oh, Michael Lynch, Daniel Yergin, and the rest of the econ cornucopians?
Certainly, if I catch something that goes against my knowledge of geology. Unfortunately, I dropped geology since scatching rocks together to determine their mineral content was not my thing.
If Lynch or Yergin start babbling about infinite supply, I will recognize everything that comes out of their mouths as BS. If they want to talk about abiotic oil, I will ignore it and get my information from a geologist. If they want to discuss ramping-up oil production, they had best demonstatrate they have at least cursory knowledge of geologic constants. I have not followed the Lynch thread as it really doesn't interest me.
