(Yet) Another Year End List 346

Posted by Hemos from the if-kansas-is-said-"kan-zize"-why-isn't-it-"ar-kanzize" dept.
gordonb writes "New Scientist has yet another of those endless end-of-year lists, "13 things that do not make sense", including such topics discussed on Slashdot this year as the placebo effect, dark energy, and the ever-popular cold fusion. I know there are a lot more than 13 things that don't make sense, such as free markets, but, oxymorons aside, this is an interesting list, nevertheless."

    The placebo effect does work! A friend of the family is a hypochondriac (I used to be a BAD one), and always has the same cold or disease as someone else. I told her that the trick to fending off hypochondria is to gently tap the underside of her chin 5 times slowly and the symptoms will go away.

    Guess what? It worked. I just made it up but I told her I heard about it on a medical show. The power of the mind is amazing, but it has taught me how easily duped we humans are. I guess this means don't trust anyone until you know what their end desire is.

    This is an interesting article, but it seems common for them to say that these unknown "problems" might all boil down to bad research -- and I believe that could likely be the answer for many. "Bad research" covers all science conundrums: either you misread the results, or previous bad research gave you an incorrect theory.

      That's not proving the placebo effect, because hypochondria's a mental state. The placebo effect is when a real illness is treated with a placebo, not when imaginary ones are treated with a placebo.

      Think about it - there's nothing odd about make-believe cures being able to affect make-believe illnesses. It's like when you are kids, and your make-believe bulletproof vest stops your friends' make-believe bullets shot from their make-believe guns. The placebo effect is like when those make-believe bulletproof vests stop real bullets.

      • The placebo effect is like when those make-believe bulletproof vests stop real bullets.
        The difference being that study after study shows the placebo effect to work, whereas the only extensive use of real bullets on make-believe armour [wikipedia.org] found the placebo armour to be sadly ineffective...

        Mental illnesses are real illnesses and have hard, acute neurological expression in the brain. There is nothing "make-believe" about something that is chronic, repetitive and deeply seated. Depression is not just something that can be snapped out of, nor can PTSD be ignored into dissipating, the fear and desperation of hypochondria comes is real. These illnesses are not merely coming from a person who is playing a casual game of make-believe who needs to get a grip. Mental illnesses are the flipside of the placebo effect: It's when your make-believe bullets pierce your real bulletproof vests.

        This isn't even looking at somatoform disorders (physical ailments that come from the toll of being in a mental illness). The truth is that the human mind is far more of a powerful, persuasive instrument than we are normally led to believe and the state of mentality is very much a physical rather than imaginary thing. Placebo effects likewise are not usually effective in helping such mental disorders, so the grandparent's point that it works is meaningful and should not be dismissed. Most likely, the tapping repetition forced the client to breath, and take note and prevent the panic that is prevalent in most anxiety disorders, which in turn backed the person away from their usual repetition compulsion, bypassing the worse part of her illness.

          Mental illnesses are real illnesses and have hard, acute neurological expression in the brain.

          Certainly some people have strong difficulties in their lives. And certainly some people have deformities or injuries to their nervous system. But the idea that "mental illnesses" such as depression have direct neurological expression is not as supported [time.com] as SSRI makers would like you to believe. (Another link: here [intenex.net].)

          Labeling psychological difficulties (other than neulogical illness or injury) is questionable [reason.com]. It has strong legal and social consequences that we ought to consider.

          The DSM, the official defintion of mental health and illness, has its roots in a military effort to decide who was too crazy (or not crazy enough?) to be a soldier. It's critera for listed condtions are famously vauge. And who decides which condtions are "illnesses"? Just a few decades ago, homosexuality was a "mental illness" according to the DSM.

          These illnesses are not merely coming from a person who is playing a casual game of make-believe who needs to get a grip.

          I agree, but that doesn't necessarily mean that we should use the word "illness" to describe these states.

      • In the article they talk about pain relief by a placebo, so pain is not a totally real bullet either: pain is quite influenced by the mind even without placebo.
        Once I shielded me for the pain of a dying nerve in a tooth by reading a book, and a dying nerve in a tooth is *quite* painful, granted this is quite different from a placebo more similar with the use of hynosis to shield a patient from pain during a surgery.
      • And think about it some more: there's nothing odd about a placebo curing a real illness either. The brain is highly connected to the body, and if you believe you are getting cured, there's an obvious pathway for that to have an effect. What would be surprising would be if people who thought they were receiving no treatment, but were being snuck a placebo in some way reacted differently from people who believed they wre receiving no treatment and were not receiving placebo.

      Bit more complicated than that -

      Inflation could have been caused by a phase change in the Higgs field, but this is a necessary-not-sufficient part of the explanation for the observed features of the universe. Then one also has to find a reason for the phase change and why it happened to have the precise characteristics needed (there's some fine tuning of parameters required in order for what we see today to pop out the other end of this process).

      Then there's of course the root question of whether the Higgs field itself exists, though a lot of the Standard Model would have to be junked in order for it not to exist.

      An unregulated free market didn't lead to Microsoft, because we don't *have* an unregulated free market
      in the United States. In a real unregulated market, without things like patents, and the bazillions of dollars worth of government restrictions and regulations required to start a business, there would be a lot more competition for MS. It would actually be much harder for monopolies like MS to become overwhelmingly powerful in a real free market, because it would be much easier to set up shop and compete with them on a level playing field.

      Of course some people say that there would be no innovation without patents... I contend that such an assertion is not true, and that the lack of artificial government granted monopolies (patents) would result in a constant "arms race" situation where companies would be forced to innovate constantly or die. Look at how military technology advances... the US is forced to constantly work on developing better battle technology exactly because there is no way to prevent our competitors from using what has already been invented. I mean, it's not like we could patent the nuclear bomb and keep Russia, China, India, Pakistan, etc. from using it...

      Give us a real free market sometime, and let's see what happens... until then it's all just speculation, because we damn sure don't have anything approaching a free market now.

The arguements against it from the chemistry experiment on the expedition don't hold up. The experiment used a mass spectrometer (MS), the set up was designed by Klaus Bieman one of the most distinguished mass spectrometrists in the world. When they got negative results and the biology experiment got positive results, they were not going to accept it and they carried out an organized campaign to discredit the LR results proposing all sorts of experimentally unreproducible hypotheses to show that the LR results were a false positive.

    Well I am a chemist and a mass spectrometrist who in my youth used to regard Bieman as an almost godlike figure. Well he was wrong. The MS results were of limited sensitivity. The most likely form microbial life in Martian soil would take is to be dormant spores waiting for the rare periods when liquid water becomes available. These spores could be in a very low level in the Martian soil well below the level that would produce sufficent quantities of organic compounds to be detectible by MS.

    The LR experiment is very sensitive. Levin was able to use it to show the presence of microorganisms in Antarctic ice cores, which could not be detected chemically, but which could be confirmed by the standard microbiological procedures of plating out. Lunar rock from the Apollo mission gave no false positives in the LR experiment.

    All the recent results from Mars probes showing both evidence for the existance of liquid water on the surface of Mars in the past and for evidence of the presence of water now, all serve to support the claim that the original Viking biology results provide a strong indication that microbial life is present on Mars. There is a case to answer. Now is the time for NASA to invest in sending a chiral LR experiment to Mars to further investigate and hopefully come up with some conclusive answers.
