Crackpottery

On the other hand, Ramanujan was "discovered" when he sent math-spam to Hardy...

I remember hearing once (I wish I could remember where) that there are two kinds of people in the world: those who want to write books, and those who want to have written books. And of the two, only one will ever have a chance of finding success as an author.

For every Ramanujan, there are a million Einstein wannabes. It is usually easy to figure them out....

"On the other hand, Ramanujan was "discovered" when he sent math-spam to Hardy..."
But Hardy said that after he examined the materials, and saw several results dealing with integrals that took him (Hardy) some time to work out, that the writer had to be brilliant because a person unfamiliar with higher mathematics wouldn't have the imagination to write the things that were in the message.
I doubt that a person who believes physicists can't see reality for the "mathematics" falls into that class.

From your points above:

1) They really do not know what constitutes knowledge, and the way one gets to knowledge. They do not understand how science works, because they were never trained in it.

2) They are incapable of taking criticism, or admitting they are wrong. Big egos help in this regard, and so does a lack of scientific training (which makes you quite humble pretty quick in grad school).

3) Once they try peddling their impressionistic ideas, they get rebuffed which makes them resort to conspiracy theories about the walls surrounding the academia. As Bob from the NPR show says at one point, scientists are too engrossed in all that mathematics to be able to see the Truth (I am confident he meant it with a capital T).

The mindset isn't that far off from that of classical creationists and the neocreationists of the Discovery Institute and the Biologic Institute, including the creators of Expelled. The only things missing are religious dogmatism and political power, the latter of which makes it imprudent to ignore them....

The book Mathematical Cranks by Underwood Dudley is a valuable compendium of crackpot math theories and their inventors, ranging from "proofs" of the "real" value of pi to new rules for arithmetic. (Instead of "minus times minus equals plus", how about "the product get the sign of the first factor"? Hilarity ensues.)

I wonder if there's a similar book on physics cranks.

Book? I will have to re-listen to the podcast of the show again, but I believe something like that exists and was mentioned.

Also, Bob's friend the journalist managed to persuade a physicist to look at the manuscript and even to talk to Bob (with disastrous results) and, well, apparently Bob thinks that momentum and energy are the same thing....an easy mistake to detect and enough to invalidate the entire idea.

That act was one of my favorite acts of any This American Life episode. The utter smackdown of that guy by the physicist makes me smile every time I hear it.

I've had a few rather strange folks show up in my blog's comment threads, but I've only received one "fractured ceramic" e-mail really worth talking about. It did display all the classic signs mentioned in this post.

All this isn't to say that scientists aren't immune to crackpottery, at least outside their fields of expertise. My Grandfather -a chemist- spent his last years trying to figure out where Michelson and Morley went wrong. It was years before I stumbled across any reference to the "luminiferous aether" outside the old man's ramblings.

nice post ... it's quite amazing how well aligned the characteristics of crackpots from different "fields" are.

I'm a geologist and have engaged with some of the abiogenic-oil crowd a bit and see all these patterns - arrogant ignorance, rampant straw-manning, the 'Galileo Gambit' rhetoric, refusal to address details, and, my favorite, associating me with the deluded groupthink of academia. I was told I was part of a "tribe" and have been brainwashed.

Another favorite tactic of their's is to claim that if you can't explain the well-established theory in a short, succinct statement that a layperson can understand that it must be invalid. And then when you do provide such a statement, they claim that it's not that simple and we really don't understand it well enough to make a conclusion. This one is rampant in global-warming denialism.

For a while, I wanted to engage with these people and naively thought they would come around if I showed them enough data (note: they don't really like discussing data) ... I was calm and never called them nuts, they will jump on any opportunity to cry 'ad hom'. They accused me of trying to 'appear reasonable'. Good times.

Brian -

I've had the same experience with the Abiogenic oil people (my original training was petroleum geology). The theory has some interesting consequences (if true).

First, if oil and gas are being continuously generated at anything like current rates of extraction (a common inference), then the magniture of pre-industrial oil seeps would have been vast - like 40 supertanker sinkings in the Persian gulf *every day*. Strange no one ever noticed..

Second, such a rate of oil and gas escaping and degrading would draw down oxygen levels. And raise CO2/methane levels. In fact, free oxygen could not exist under the Abiotic world.

Third, and this is the one that will never get absorbed in their brains, if it were true, then the oil majors could use it to put OPEC out of business. This being the same OPEC that took over all the oil major's big assets in the 1960s and 1970s. So this conspiricy theory means that the world's biggest oil companies are being very charitable to the same governments that took their best assets.

The 'argument by being ad-hommed' is a Crank Classic... The Crank is, of course, allowed to make any ad hom, factual error, logical error or baseless assertion that they feel like, wheras even the slightest hint of mild impatience from the scientists instantly proves the Crank correct.

Andrew ... thanks for the comments re abiogenic stuff ... I never thought about the oxygen implication.
