Now, ‘there is at least one kind of fruit, that is good for you, in at least one specific amount’, that’s entirely different hypothesis, and must be stated as such.
Indeed it is. Since you are aware of this, one wonders why you choose to uncharitably interpret hormesis in the broadest simplest possible way.
edit: also, for your information. I’ve added some of the cautious-sounding parts of the article myself a while back. So thanks for compliment.
So your disingenuousness is all the more irritating and willful.
Their theories may be most directly testable via negative results other than cancer. The Hormesis cherrypicks out of those studies some net benefit. It may still turn out, that we will be willing to trade the negative effects, if any, for reduced cancer rate, if ever—or not. That is up to real science to decide. Not up to ‘hormesis’ studies.
So to rewrite what you are saying, “Hormesis—as anyone but me defines it—exists as an effect in studies, but it’s still all pseudoscience and ‘real science’ needs to investigate it.”
Go read “biological effects of ionizing radiation” or some mainstream knowledge on the topic, please, before asserting that my opinion is not mainstream, and what is the mainstream view of hormesis is, and rewriting what I am saying.
Especially, do some homework assignments so you have some idea of e.g. how often a cell is hit by ‘radiation’ at near background level, so you see how plausible it is that the low doses—which affect things stochastically—have any sort of nonlinear effect.
Then delve into controversial stuff like hormesis.
That’s actually a great heuristic: do not learn science from controversial stuff. Learn topic properly first. Before learning radio-biology, learn some physics, and biology. I’m pretty sure I seen an article to this sense on lesswrong. The reports like BEIR, that’s the summarization of knowledge by experts. Wikipedia is a lack-of-scholarship bias. The wikipedia article on the topic would of been best balanced and most accurate by citing precisely 1 mainstream meta-report. Any balancing has already been done by far more qualified experts than Wikipedia editors.

The existence of hormesis in some examples to some degree is not disputed in the mainstream. All the arguments are about how widespread it is, how important it is, what the mechanism is, whether particular studies properly controlled for various issues etc. In other words, ‘normal science’ in the Kuhnian sense.
If you want to claim something like ‘the mainstream view of hormesis is that no form of hormesis exists to any degree in any context whatsoever’ and that hormesis is entirely outside the current paradigm, I am going to have to call BS on that and demand citations.
Hormesis has been defined as “the stimulating effect of small doses of substances which in larger doses are inhibitory.” As stated by Wolff (1989) the meaning has been modified in recent times to refer not only to a stimulatory effect but also to a beneficial effect.
The wiki disposes entirely with stimulatory meaning. The stimulatory meaning is sensible. Stimulation may, or may not result in positive response (typically doesn’t, can result in super linear negative responses just as well), which depends to type of stimulation. The beneficial one, is pseudoscience, and term hijacking as well, to list all the studies in the stimulatory sense as support.
BEIR V discussed the effect of confounders and the ecological fallacy2 in the evaluation of high-background-radiation areas and concluded that “these two problems alone are enough to make such studies essentially meaningless” (NRC 1990).
...
Ordinarily, epidemiologists do not consider ecologic data such as this as being sufficient for causal interpretations. Since the data are based on populations, no information is available on the exposure and disease status of individuals. Such data cannot be controlled adequately for confounding factors or for selection bias. Although ecologic data may be consistent with an inverse association between radiation and cancer, they may not be used to make causal inferences.
which is how you call something “pseudoscientific BS” when you are writing that sort of report.
And finally, after politely saying many very bad things about it,
The committee concludes that the assumption that any stimulatory hormetic effects from low doses of ionizing radiation will have a significant health benefit to humans that exceeds potential detrimental effects from the radiation exposure is unwarranted at this time.
Emphasis mine. Also, going to edit the wiki sometime with the latest BEIR, this replacement of stimulatory meaning with beneficial (without citing that it was originally stimulatory) on wiki is certainly not a good thing.
The whole notion of beneficial effect needs to go way down as a speculation that positive effects of multiple stimulations will outweight the negative effects, and the curve might look so and so, albeit the dose range is unknown.
And your cherrypicking continues. Your link specifies repeatedly that it is only discussing radiation hormesis, and drawing on sources about radiation hormesis. Radiation hormesis is the most controversial form of hormesis. Notice that they didn’t conclude that no form of hormesis exists, which they really should have since a fortiori that subsumes any discussion of radiation hormesis...
which is how you call something “pseudoscientific BS” when you are writing that sort of report.
It makes perfectly sensible criticisms of epidemiology, which apply to all sorts of things like the War on Salt or cholesterol and not just radiation hormesis. I agree, such studies are extremely weak.
But do we just have epidemiological correlations for radiation hormesis—much less all the other forms of hormesis?
Ahh, okay, sorry, I misunderstood your point as applying to ‘radiation hormesis’, because that was what i was originally talking about.
Other hormesis—sure, some chemicals have hormesis effects. That’s a fact. Much misused fact (by homoeopathy practitioners), but a fact. Implies absolutely nothing about radiation hormesis. edit: and i don’t see why even have a mental bin ‘hormesis’ for vastly different mechanisms by which something bad may be good in small doses.
edit:
I agree, such studies are extremely weak.
I would say, they are essentially meaningless. Essentially is empty word that you add not to sound too nasty.
edit: by the way, on other hormesis. The original thing I has posted in this thread, was:
The thing about toxicity though—not all poisons have any effect whatsoever in low doses. Some do have effects that don’t go to zero at low doses—radiation for example—because it does not dilute below 1 particle track through nucleus, which is harmful. The carcinogens in general, as they don’t dilute below causing 1 mutation to dna in 1 cell, which has probability of harm. But organic compounds which are not carcinogenic—not as in natural but as in organic chemistry—and especially those from plants, they may well be entirely harmless at the doses below those that actually result in toxicity. Of course there may be situations where they are ‘the last straw’, but in general not everything is harmful all the way down.
I did specifically note that just because radiation and carcinogens have linear effect (as commonly accepted by mostly everyone in the field), does not mean other poisons do. You absolutely can’t accuse me of being unfair towards other examples of ‘hormesis’, (albeit it puzzles me why one would bin all those drastically different mechanisms and effects together under same label)
Peace, now? I know my biological effects of radiation stuff. I am passionate about the subject because the failure (unwillingness) to apply LNT results in preventable human deaths. It is not abstract problem. I don’t bring deaths up because there’s accusations of emotional bias. Can i be allowed to be passionate about subject with deaths attached, if I am entirely (and very boringly) mainstream in my scientific opinion, AND actually have argumentation I understand? All the stuff of how hard for the cell it is to detect the ‘low doses of radiation’ (which are a track once in a blue moon). Other stuff like this. It’s a complicated subject. The radiation been fascinating me since I was little, and I read on it as hobby. And i study from mainstream sources before reading controversial ones.

You dismissed the area of research as unscientific self-serving wishful-thinking pseudoscience, which is demonstrably incorrect and sits poorly with me as devaluing the meaning of terms like pseudoscience which should be reserved for pernicious things like homeopathy. Radiation hormesis is highly controversial, may not be true, and has methodological issues with some of its results, but this is all ‘normal science’ and not pseudoscience, and looking into it is perfectly scientific.
If nothing else, the other areas of hormesis mean that it is more plausible that radiation hormesis would also exist and looking for it may not be privileging the hypothesis. If no one had ever found any kind of hormesis, that makes radiation hormesis especially unlikely! and so by symmetry, finding other sorts of hormesis make radiation hormesis a little more likely.

I dismiss the health benefits notion. Did you read that BEIR link? How come they aren’t convinced? Of course they stay polite and don’t call anyone self serving. That’s not their job to look into motives.
and sits poorly with me as devaluing the meaning of terms like pseudoscience which should be reserved for pernicious things like homeopathy.
Pseudo-science is something that looks like science to careless contemporary observers, okay? That’s the original meaning of the word. Phrenology looked like science to contemporaries. Freudian psychoanalysis did. Bloodletting did. And so on. None of those topics were readily recognized as cranky by contemporary average person (even though the scientists generally dismissed them as unscientific, non-testable, and non-predictive)
Homeopathy barely looks like science to anyone any more. It’s a non-science, and much of the followers cherish the notion that it is non-science (they say, we ain’t trusting scientists).
I, instead, find that restriction of notion of pseudoscience only to cases plain obvious to most careless contemporary observers (us), devalues the notion. The pseudoscience is something that can fool you, or that can fool me. It can’t fool most scientists, hence the BEIR very briefly dismisses all of it [rad. hormesis]. It can fool average person, hence wiki doesn’t do the same.

See the original post of mine that started this giant controversy. I explained why, exactly, one shouldn’t do precisely this, the other way—conclude negative effect of low doses of poisons, from the negative effects of low doses of carcinogens. The physics here is not symmetrical.
I was going to continue this, but then I noticed that almost all my karma is gone (!) and most of my comments in this thread are at −2; your comments are also doing pretty poorly. (Not my doing. I try not to downvote any comment I am replying to.)
If I keep this up, I won’t be able to post and my commenting will be rate-limited (which I hate), and the fact that we’re both getting downvoted indicates LW in general finds this a worse-than-worthless discussion, so… I’m going to bow out, as much as I dislike not having the final word.
EDIT: and this gets upvoted almost immediately! You know guys, you could just leave a comment like ‘I don’t think this discussion is very productive, maybe you should stop’ and not rely on the karma system with its crude numbers to convey your desires.
they are afraid of karma system, what if we both downvote them together. Also they are still reading, implying some sort of interest in the issue. My karma loss is mostly from posting something controversial in main for 7 downvotes, 70 points.
edit: btw if someone’s coming in consistently to downvote, that person doesn’t want discussion to stop as easy way is to stop coming in, it’s not like this expands all the way. edit: could even be worse. downvoting so we think we are downvoting each other, hence get pissed off more.
What does follow, is you making fairly strong evidence of you coming here just to vote, for many pages, until a post is made that gets you to post. Don’t like it, don’t read it, and don’t talk here of the people who just click on the list of recent posts, that would fluctuate wildly.

I agree with you on hormesis being plausible. But the two of you generated some fairly low-quality discussion. The downvotes are understandable.
People are giving you karma because they don’t actually want you to suffer real harm (rate limiting).
Most people would steer clear of interfering in a street brawl. An anonymous downvote is like calling the cops :)
“real harm”?!?
Ok, that was funny. I just meant to indicate that it seemed a heartfelt and direct plea by Rhwawn, a person acting in good faith.

This does not follow. People who prefer a conversation to stop most certainly can be expected to downvote comments in that conversation. It works.
(In case Rhwawn was wondering, this does not suggest that I am the one who downvoted them. I don’t recall doing so in any near context.)

How dare you insinuate that I read the recent comments thread, vote as I deem appropriate and then sometimes comment myself!
Oh, no, wait. That’s more or less accurate. Yet somehow you seem to be using it as a vile accusation.
Yea, and the first one to comment being the one i disagreed on the evo psych about, totally doesn’t propagate anywhere.
