Nine Crazy Ideas in Science
Here's the deck of nine ideas under consideration:
- More Guns Mean Less Crime
- AIDS is Not Caused by HIV
- Sun Exposure is Beneficial
- Low Doses of Nuclear Radiation Are Beneficial
- The Solar System Has Two Suns
- Oil, Coal, and Gas Have Abiogenic Origins
- Time Travel is Possible
- Faster-than-Light Particles Exist
- There Was No Big Bang
So in this review I'm going to give you generalities first, and bury "the butler did it" type information after a SPOILER warning.
One of the problems with the execution of this work is that you can pretty often tell when Ehrlich is enthusiastic about an idea just from his general tone as he writes about it... and conversely, in retrospect I think I should've been able to spot when he disagreed with, because the writing in those chapters was a little confusing.
Part of his schtick is that at the end of each chapter he rates the idea on a scale of 0 to 4 "cuckoos". Oddly enough I often find that I strongly disagree with his cuckoo ratings even just based on the evidence that he presents. But the absolute magnitude of my disagreements are typically no more than a single "cuckoo".
I was worried about some of his evaluation criteria (see the introduction available on-line as a sample chapter), because he includes several points that strike me as fairly dicey: "Who proposed the idea?"; "How attached is the proposer to the idea?" and "Does the proposer have an agenda?" These all relate to judging the person rather than the idea itself. (Consider that "consider the source" and "ad hominem argument" are pretty much the same as far as logic goes.) But he does clearly understand that these are just rules of thumb, and I note with some amusement that he doesn't resort to these particular rules anywhere in the later chapters. He's more interested in the logic of the arguments, which is as it should be.
I could bring up lots of quibbles (and I probably will after the spoiler warning), but overall I found this to be a great breezy read. I learned quite a bit from it. While nothing here made me do a reversal of my beliefs, I was often surprised that the evidence for something was stronger or weaker than I'd supposed.
Here we have an educated, astute, person doing a relatively independent review of some controversial, interesting technical subjects. Why aren't there more books like this?
Ah, but at least there's one more! I see that a sequel has just come out: Eight Preposterous Propositions: From the Genetics of Homosexuality to the Benefits of Global Warming . I bet I'll be submitting a review on that one shortly ...
Anyway, now into the nitty gritty. Here's your SPOILER WARNING. Skip the following if you want to play the "guess where he's going" game with this book. Let's take it chapter by chapter:
More Guns Mean Less CrimeI'm a "right to bear arms" kind of guy myself, and I was surprised that the data doesn't seem to support private ownership of guns as a crime deterrent. Ehrlich argues persuasively that the statistical evidence for this is very weak. I appreciate the fact that Ehrlich concludes that both the pro and anti gun sides are nuts: he rates them 3 and 2 "cuckoos" respectively, where a 3 is "almost certainly not true" and 2 is "very likely not true."
But here, we come to my first strong disagreement with him. If the effects aren't strong enough to measure, why the asymmetry in the "cuckoo" rating for the pro and anti side? I might rate them both at a 2 myself.
AIDS is Not Caused by HIVI've had the impression that the the Duesberg hypothesis was pretty screwy, but I was willing to tentatively consider it might have something of value. For example, what about the possibility that multiple diseases are now being diagnosed incorrectly as one single syndrome "HIV"?
But Ehrlich's analysis satisfies me that there's not much of scientific value in Duesberg's ideas at all. I don't argue with his 3 cuckoo rating (but I wouldn't blame you if you thought it deserved the full 4).
Sun Exposure is BeneficialEhrlich concludes that this looks fairly plausible, and gives it a 0 cuckoo rating, pretty much as I would have expected. Many people might find this surprising though, certainly the popular impression these days seems to be that sunlight is deadly.
Low Doses of Nuclear Radiation Are BeneficialHere, Ehrlich lays out the case for "radiation hormesis", and I really don't think this is that fantastic a notion (the difference between a poison and a medicine is often a matter of dosage, why wouldn't this be true of radiation?). But radiation is so demonized in the popular imagination that "radiation is good for you" comes off an insane joke. Ehrlich takes it seriously, and essentially concludes that while there are reasons for suspecting that this effect exists, it hasn't been entirely established. And here we have one of my quibbles: he awards it 1 cuckoo, which translates to "probably not true, but who knows". But there is no reason for saying it's probably not true. If something is not crazy, just not established, I would be inclined to award it "0 cuckoos," aka "Why not?"
The Solar System Has Two SunsThis is the "Nemesis" hypothesis, which it will probably come as no surprise is rated at 2 cuckoos. The short version of the story: originally they looked at part of the extinction record, and it looked like there was a definite cycle. But if you look at the whole record it doesn't seem to be there.
Oil, Coal, and Gas Have Abiogenic OriginsThis is subject that's been of some interest to me, ever since I heard Thomas Gold give a talk on this idea about a decade ago. It turns out that this is now looking much less like "an intriguing possibility" and much more like a truth awaiting a few funerals before it will be declared established. The odds are good that "fossil fuels" don't actually come from fossils, rather they're from hydrocarbons that pre-existed the formation of the earth, which means we're probably not going to run out of them. (So that means we can ignore those environmental wackos, right? Nope: imagine what happens to the atmosphere if we keep ramping up the rate at which we burn this stuff.)
Ehrlich rates this at 0 cuckoos, but maybe he should have invented a "-1 cuckoo" for this one.
Time Travel is Possible2 cuckoos: no surprises.
Faster-than-Light Particles ExistEhrlich mentions in his introduction in the interests of "full disclosure" that he's actually strongly attached to one of the ideas discussed here (the existence of tachyons), but by the time I'd gotten to that chapter I'd entirely forgotten about this, and I was disappointed to realize that he was being an advocate, not an independent reviewer (it includes a picture of him wearing a "no tardy-centrism" T-shirt).
Ehrlich rates this at 0 cuckoos, but come on. Even just based on the write-up he presents, it's a clear 1 cuckoo.
There Was No Big BangClocks in at 3 cuckoos, as you might expect.

I mod this post "-1, Cuckoo".
In Soviet Rush, today's Tom Sawyer gets high on you.
...atomic power should be a consumer product. Many people would rate this as a 4 cuckoo because of the "danger" of terrorists developing a nuclear weapon. The truth is that atomic power is exceedingly easy, safe, and clean to produce and should be a zero cuckoo idea. Don't think that they'd completely rid us of batteries tho. In order to power your car with a RadioIsotope Generator (non-fission), you'd need hundreds of pounds of plutonium. However, if combined with batteries, you could reduce the amount of plutonium significantly, and have an auto-recharging electric car. Sure, it means a few more pit stops on long trips, but you NEVER have to refuel!

I'm not a geologist, but I was under the impression that fossils are regularly found in coal, and that we've observed the intermediate steps of its formation from peat bogs.
When it was first thought of, the theory of relativity was just a 'crazy idea'.
So was the Segway.

--- Worst tagline ever.
No, I don't think it ever was considered a "crazy idea" at all, at least not by anyone who understood it. It was a hit right out of the chute.
"Intelligent Design" is neither a particularly new theory, nor a particularly compelling one.
The chances of all of those variables being "perfectly tuned" to allow human life to evolve are certainly small, but are only statistically interesting if you presume that human life was some sort of universal "goal" from the outset. At that point, arguing for Inetlligent Design is just question begging.
Yes, and so were (and are) a bunch of ideas which truly are crazy. Just because one can point to examples of theories that at first sounded impossible which later were accepted as fact, doesn't mean that all (or indeed, many) of them are.
In other words - for every crazy idea that turns out to be right, there are 999 that are just plain crazy. The fact that one turned out to be correct doesn't in any way validate those which are just plain wrong.
Intelligent Design is just the latest attempts of the creationists to pretend they are scientists. It suffers from the same flaw as other such "theories" -- it presumes that which it seeks to prove. In a nutshell, their argument is that life is too complicated to have arisen from a random process, so must have been created by some intelligence. In other words, we can't explain it, so it must be god.
Re guns: If the effects aren't strong enough to measure, why the asymmetry in the "cuckoo" rating for the pro and anti side?
Because (like the vast majority of such things) the pro- and anti- positions are themselves asymmetric -- the anto-gun position is not a simple negation of the pro-gun one, similarly the pro-life position is not a simple negation of the pro-choice one.
It's something quite a few studies like this one suffer from, too many fall foul of the same few logical fallacies.

The real difference between his 'crazy idea' and these 'crazy ideas' is a matter of defined mathematical equations that proved to be true. As I see it, these theories are only conjectures as ways things might be with no truly defined methodology for it's reasoning other than, "hey, why couldn't it be this way instead?" (If that's true, pull up a chair and I will tantalize you into the next century with 'crazy ideas' :) ) I understand it's possible all of mathematics could be a joke, but from what I have studied and know it would be highly unlikely for that to be true. Therefore, once we were able to prove his theories in lab settings, it became no more then an abstract theory and a revolutionary way. His numbers proved correct down to an arbitrarily defined decimal.
While both ideas are crazy, don't argue if you don't have some overwhelmingly surmountable proof other then a work that explains a brilliant theory in an extremely abstract way. That doesn't make the theory out to be crazy in and of itself.
Intelligent design should be 3 or 4 cuckoos, because for every argument that exists in favor of ID, there's a better argument that shows why that argument is a fallacy.
For example, the argument you gave about the extremely unlikely odds that we would be here is trivial to refute. ANY event that happens is dependent on an extremely unlikely chain of events. Any little shift in that chain, and poof, the entire thing is completely different. For example, a big lotto win for Bob XXX in Des Moines is an extremely unlikely event. The odds against it are unimaginable, and any little change would have made Bob XXX lose the lottery. Even a little molecular sized disturbance in the airflow propelling those little balls would have done it. Nevertheless, people win the lottery almost every week. They beat the unimaginable odds.
After Bob XXX won the lottery, would Bob be justified in thinking that he won the lottery due to intelligent design? No, because if he didn't win the lottery, either someone else would have won, or nobody would have won. When he looks back at his lottery win, it's hard for him to see that *all* the possibilities were equally unlikely to happen, but one of those possibilities *must* happen.
When you add up the probabilities of every extremely unlikely event, you always come out to exactly 1.
Please, present more arguments, and I will present the superior counter-argument. Intelligent design is very interesting to think about, and studying it can be an instructive act in itself.
This is America, damnit. Speak Spanish!
Well duh, that is one way our body makes vitamin D, if I remember correctly. It is the amount of exposure that matters. Speaking of sun exposure, my favorite university memory of walking across the medical school campus was the cluster of smokers puffing away and sunbathers roasting right next to the Cancer Research and Treatment Center sign. One of these days I have got to take a picture of that.
I Am My Own Worst Enemy
There is no greater proof that science has won the Evolution VS. Creationism argument than the "Intelligent Design" theory. The religious right knows that they cannot win with a "faith based" argument in this day and age, so they've resorted to rhetorical jujitsu and created "Intelligent Design" theory. (Intelligence Design summary : the world is so gosh darn complex that SOME higher power must have created it, right?).

Most scientist will assume the ideal situation and assume that colleagues are playing fairly. Therefore, the system is fairly easy to game, for at least a little while. All it takes is a small group of 'scientist' with an agenda. This usually involves some idea that they really want to be 'true'. These characters only need to selectively choose demonstrations and filter data in such a way that their 'truth' is shown to result from the data. Of course real science has great difficulty defending against such attacks because, as in all things, playing by the rules to discover truth is vastly more difficult than just asserting something is true and then picking the few examples that support the position. Even when no malice is involved, such fictions have taken years to disprove.
In the case of softer sciences, or even the harder sciences where duplicating of demonstrations are really difficult, the credibility of the person is critical. The ease by which such sciences are gamed is the reason why we have so much confusion over a variety of social issues, even though the basic consensus is amazingly clear. OTOH, consensus can be wrong, which is why science uses resources to look at all sides of the issue
As an aside, the physicists, and really scientists in general, I know are extremely open minded. They just get jaded after a while due to the number of malcontents that abuse science to promote personal doctrine. To a trained and logical mind, the rhetoric some of these idiots spout is really equivalent to just throwing throwing feces everywhere.

From the original Slashdot article:
Science is a human endeavor. It's conducted by humans. Science is a process, however, and that process is defined in such a way that it doesn't matter which humans conduct it.
Perhaps with homeopathy and other forms of medical quackery coming as a close second, "creation" "science" is the canonical example of why "Does the proposer have an agenda" and "How attached is the proposer to the idea" are important questions you have to ask yourself when evaluating a theory.
The scientific method is independent of humanity. Any sentient being is capable of doing science. But to the best of our knowledge, the only sentient beings that are performing science are humans. We know from observation that humans are fallible. Humans let their emotions get in the way of the facts. When a human is very attached to a theory, and even more so when a human has an agenda that can be advanced by promulgation of that theory, it's not guaranteed, but it's highly more probable, that the human will depart from the scientific method in an effort to cling to a theory that's been repudiated.

ID is a nice belief system if you're already a creationist who accepts on faith that the Universe was created by the God of Genesis (optional: 6,000 years ago in a week), but it's not science.
For the record, I'm not bashing Christians here. Frankly, I see zero inconsistency between Genesis and our presently-understood notions of cosmology. Take a guy from 4000 BC and show him a PBS documentary on current theories of cosmology, and ask him to write what he saw. You're likely to get something like "Umm, I saw this vision with moving pictures about how the universe came to be. So, like, first there was nothin'. No time, no space, zilch. Then Something Happened, a couple of branes smacked into each other and nobody knows quite what that means yet. But that was the start of our universe. Then they said something about electromagnetic force breaking symmetry with the weak force, which I couldn't understand, and there was light, which I could understand. Then it cooled enough that the mean free path of a photon got pretty long, and I didn't know what that meant, but that was when it b
I think the non-fossil origins of oil and other subterranean hydrocarbons is just about a lock. Of course, I'm not any sort of chemist or geologist, but the idea that only biological processes can produce hydrocarbons has been in trouble ever since we found out Titan has a methane atmsophere (aka "Natural Gas").
When you consider how much biomatter would have to have been tied up in swamps and then covered in just the right ways and held at just the right pressures and temperatures to produce the amount of oil and coal we've already pulled out of the ground, and how inefficient that process would have to have been, the "fossil" explanation becomes pretty unlikely. When you look back at the history of that explanation, it becomes pretty clear that nobody cared much, then someone noticed plant leaves and bark patterns in some lumps of coal and everyone said "Oh, that must have been it." (HINT: Petrified forests weren't grown by stone trees)
Cook's theory isn't really "abiogenic", BTW. The only abiogenic "fossil fuel" under his theory would be plain methane. Rather, he believes that methane left over from planet formation is steadily separating out, and somewhere in the mantle (around 10-30 kilometers subsurface) a bacterial ecosystem based on sulfides and methane is forming it into complex hydrocarbons. Given that we already know of sulfide-based, high-temperature ecosystems in the deep ocean thermal vents, it's really not much a stretch anymore.
By that theory, the oil-richness of the Middle East becomes inter-related with the East African Rift (both being the consequence of a deep upwelling of methane-rich rock). But we're going to have to wait for those funerals before it will be acceptable for a petro-geologist to admit they have been back-asswards about it for the last century. The "Appropriate Technology" bunch is going to have a screaming fit, as well.

The Cuckoo rating is entirely irrelevant. Consider the Big Bang Theory. It hasn't yet been formally accepted (as a Physical Law*) by the scientific community, yet the author considers the notion of the Big Bang never happening to be nonsense?
There is no such thing as "formal acceptance" there isn't even really such a thing as the "scientific community". The big bang is generally accepted as the current best theory by the majority of astrophysicists. Does this mean it is true? No, it just means its the theory that fits most consistently that observational and experimental data currently available to us.
The fact of the matter is, the scientific community has been wrong more often than right. With further investigation, ideas are refined, and those that don't fit the observations are rejected.
That's correct and exactly the way it should be. Science is a process, not a collection of laws or facts. You gain knowledge of the way things work by applying the scientific method. That means that the set of best theories is constantly being re-evaluated and changed. That's a key differentiator of science from (for example) dogmatic religions.
But the process takes a long time. For nearly 2,000 years the best Western thinkers believed that the Earth was the center of the universe. That's a long time to be wrong about something so big.So even though I believe that the scientific method has its merits, I recognize the limitations.
As opposed to which system? The limitations of the scientific method are usually limitations of our ability to gather data. We can't attach more certainty to theories like Big Bang or Evolution because we have incomplete data to work from, for obvious reasons. That's not a limitation of the scientific method at all. If your notion of gathering knowledge is not based on the evidence available, then you are in a considerably worse situation that science can give you, incomplete though that may be.
If I had a time machine and could travel to the future, I would not be the least bit surprised if 500 years from now the Big Bang theory and Evolution were considered myths from the past.
While that's certainly a possibility, its much more likely that they will be considered incomplete. Much as Newtonian physics wasn't replaced by relativity, it was just seen as a particular case of relativistic physics at "low" speeds compared with c.
Even now, there's substantial logical and statistical problems with the "proofs" of Evolution.
Not really. Would you care to cite these supposed problems, or are you just trying to argue from authority?

I guess sympathy is why he's got Hawking Radiation named after him, holds Isaac Newton's chair at Cambridge, is a Fellow of the Royal Society, and have won the following awards:
- Eddington Medal
- Einstein Medal
- Maxwell Medal
- Heinemann Prize
He may be controversial, and have been wrong in the past, which he is the first to admit, but his track record shows quite a few leaps of thought that turned out to either be correct or possible but currently unprovable.

The theory is there's a companion dwarf star to our Sun 1-3 light years away. Here's some info.
In special relativity, faster than light travel (FTL) implies time travel quite directly.
So to treat the two subjects as being significantly different means to be working in a theory other than relativity.
Special Relativity (SR) is nice and simple but fairly limited in scope, but agrees extremely well with experiments within that scope.
Its extension to cover gravity, General Relativity (GR) is extremely elegant, and also agrees well with experimental observations, but is not integrated with the rest of the infrastructure of fundamental physics (quantum physics, quantum electrodynamics, the Standard Model...)
So general relativity may eventually become obsolete, even though currently it's currently a great theory, and whatever replaces it may modify special relativity too. So this isn't some kind of absolute statement.
Still, in the absence of a theory that is trying to supplant relativity, FTL implies time travel. Presumably the author of the book knows this, despite listing FTL and time travel as two different subjects.
For more info see these two sections of the relativity FAQ: relativity: time travel and relativity: FTL , hosted by and partly written by John Baez, a quantum gravity researcher with impeccable physics background (I've done some online study under him; he's also a fantastic teacher).
Professional Wild-Eyed Visionary
Even now, there's substantial logical and statistical problems with the "proofs" of Evolution.
Are you refering to darwinian ideals of evolution, or the concept as a whole?
True original darwinism as the sole motivator for the changes in species over time is being challenged, but the concept as a whole - that life came from very simple beginings and has changed/adapted over time is not. The mechanisms involved are what are being challenged - such as the idea that small changes in genotype over time that favor the survival of a particular subset of a species lead to massive changes in the long-view. Fossils for the 'in-between' variants are not being found, hence it is becoming more widly accepted that large leaps are made, and that such large leaps could actualy be triggered by environmental pressure.
However, these new mechanisms being discused and discovered are just that - mechnisms. Evolution as Darwin envisioned it may be being disproven, but the idea that life evolves over time is not.
If, instead of refering to darwinian evolution, you are refering to evolution as a whole - then you are seriously mistaken. There is no creationist or other theory of life that is being pushed ahead of evolution by scientists. The logical and statistical problems you mention are about the problems with darwinian evolution and its mechanisms.

Someone find me an oil or coil reservoir outside of a sedimentary basin, and I'll swallow this B.S. That some methane may have abiogenic origin is conceivable, but the natural gas we collect now is clearly primarly biological in origin. Petroleum geologists are not so dumb that they could so seriously wrong about the origins of petroleum.
The data on gun ownership alone is not particularly correlated with crime deterrent, but that's conveniently ignoring the data on concealed carry licenses published by John Lott, not-coincidentally in a book called "More Guns Less Crime"
His data showed a consistent and predictable decline in violent crime after the passage of concealed carry laws. Furthermore his data shows that violent crime was exchanged for crimes where there was less risk of meeting a person during commision (car theft, etc). Both of these are consistent with basic economic hypotheses (ie. greater risk costs means less people participate)
Of course when it comes to criminals evaluating their risks, it doesn't matter how many people have guns locked in cabinets at home, it matters how many people MIGHT have them hidden under their jacket.

inflation, but still an abrupt origin in the 10-20 Billion Year range.

This isn't so much a comment about the book as about the person who reviewed it here on slashdot and posted the article. The reviewer makes the same mistake repeatedly, of assuming that if an idea hasn't been proven wrong, than it's proponents don't deserve a cukoo rating at all - it should be zero.
No. That's not how it works. When positing the existence of things, or putting forth an explanative theory to describe why things that are there got that way, the burden of proof is always on the positor. Therefore someone who is willing to believe a theory purely because it hasn't been proven wrong DOES deserve at least a little cukoo rating for that.
Don't label something "offtopic" unless you know the topic well enough to tell what's on topic.
Actually, mathematics has been proven to be true. One of the classical masters (I believe either Plato or Aristotle) laid the work for it; Basically he took basic set theory
He did? This is interesting since formal set theory wasn't formulated until the mid-nineteenth century. Aristotle did come up with the axiomatic system of deriving all possible truths from a basic set of simple truths, but that's hardly set theory as such.
which is not mathematics but a logical framework that is provably true, and used it to prove that all mathematical operations of the time is also provably true.
Except of course the ones Euclid couldn't prove to be true so he assumed them to be axioms - some of which were later derived from the other axioms.
Certain modern mathematical concepts, most notably i (the square root of negative 1) were not included in this treatise, however.
Imaginary numbers were encountered by mathematicians in the sixteenth century and established as a concept by the early eighteenth century - hardly a modern concept. By comparison set theory, linear algebra and statistical probability theories didn't emerge until late nineteenth/early twentieth century!
And you reply: "Good argument!! There are lots of irresponsible idiots so don't let anyone have guns."
So, you have never seen an 18 wheeler in your life, have you?
Who, the HELL, is modding that crap up? Seriously, what is wrong with you. I say "restrict", I get trolled with semi-litterate idiots who say that I said "ban".
Is this bizarro slashdot or something?
Why is it not possible to have a fucking rational discussion about guns when people from the U.S. are around? Its not that hard people: read what the other person actually wrote, not what you are expecting to read!
On to the rest:
So it's OK to let irresponsible idiots drive 3000 pound cars.
No, its not.
And it's OK to let irresponsible idiots buy chainsaws.
Please, PLEASE look up murder statistics. Compare numbers of homicide with firearms to homicide with chainsaws.
Please.
You can't take the sky from me...
Few atheists, if any, will claim that proof of evolution is somehow proof *against* the existence of God. (Most atheists are aware of the fact that you can't prove or disprove the existence of supernatural entities like God, for whom there cannot, by definition, be any evidence.)
This is a problem with people, not with the scientific method. If you can suggest a better method for accurately determining the nature of the universe, I'm sure everyone would be glad to hear it -- but right now, science is the best method we have."Destroy science and religion. Science would re-emerge exactly the same; but not religion." - Penn Jillette, paraphrased
