Hints of a Link Between Autism and Vinyl Flooring

SpuriousLogic sends in a link from Scientific American to a study by Swedish and US researchers that reaches the surprising conclusion that there may be a link between autism and vinyl floors. "Children who live in homes with vinyl floors, which can emit chemicals called phthalates, are more likely to have autism, according to research by Swedish and US scientists published Monday. ... The scientists were surprised by their finding, calling it 'far from conclusive.' ... The researchers found four environmental factors associated with autism: vinyl flooring, the mother's smoking, family economic problems, and condensation on windows, which indicates poor ventilation. Infants or toddlers who lived in bedrooms with vinyl, or PVC, floors were twice as likely to have autism five years later... than those with wood or linoleum flooring. ... Several scientists who did not participate in the study cautioned that it has too many limitations to draw conclusions, but they suggested that new studies be designed to look for a connection between autism and indoor air pollutants."

      I can't tell what you're saying. Are you actually trying to say "correlation is causation" because that is simply not true. Correlation is not causation, but hell that isn't even what most people say. "Correlation does not imply causation" which is also true, correlation doesn't say anything about the nature of the relationship between two events.

      Part of the problem is the fact that it is easier to get diagnoses as Autism. In the past minor forms of Autism were ignored or just considered bad behavior, Even Moderate-High Autism the person was just considered Stupid. So the past records are faulty. Espectially before the age of Vinyl flooring.

    They once analyzed all the constituents of coffee (hundreds) and found that a quarter or so of them are carcinogenic. So we all should be pretty much dead by now.
    So how do you study carcinogenicity: Simple. You feed a couple of rodents that you don't particularly like 5% of their bodyweight of a certain stuff each day, and see how many of them develop cancer within their short lifespans. Now comes the fun part: You extrapolate the 5% bodyweight daily ratio to 1 ppm bodyweight daily ratio, and similary divide the rate of mammal acquiring cancer. Voila, a new PhD promotion based on the completely meritless assumption that there is any kind of linearity involved in these rates.
    I know a lot of current research is not so stupid, but most of the 1970's cancer scares were based pretty much on the scenario I just described.

    Determining whether or not a compound is carcinogenic in humans is extremely hard, except for the really bad ones.

    "correlation is not causation"
    Its very unfortunate that everyone in the world doesn't know the difference. It would solve so many problems in the world, if everyone was forced to learn the difference throughout school and in everyday adult life. Everyone would find life so much better as so many arguments would be avoided and things would get fixed quicker. The people behind funding education in science need to focus a vast amount of time, money and effort into promoting understanding in this simple yet vital bit of education. (I would go as far as to say we need a day per year to remind everyone, like a "world correlation is not causation day!" ... and i'm not joking, we really need to get everyone in the world finally past this stumbling block.

      See, the biggest problem with "correlation is not causation" is that it's a tool most frequently used by post-conclusion rationalizers -- people who start from a conclusion, and then create a rationale to justify it. Such people only feel compelled to discount evidence that runs contrary to their conclusion, which is much easier than actually justifying one's position in the face of alternatives. "Correlation is not causation" is a very simple formula for discounting overwhelming bodies of evidence.

      Yes, while the correlation != causation is a time-honored /. tenet, the researchers here do actually clearly grasp this concept, note all the clear caveats on just the summary.

      To -prove- a causation requires a correlation.
      You can either theorize a causation and later prove correlation (Einstein/Relativity)
      Or find a correlation and later construct a causation that explains it (Gravity, Why girlfriends dump guys after they show off their Battlestar Galatica action figure collection) [often requires additional specific correlation experiments to rule out other causation theories]

      In this case, I think the researchers have made fair statements about their work, that it indicates a general direction to continue to look for a causation.

      However, you will have correlation if there is causation.

      No, they're not necessarily important, either.

      No, it's vital. Correlation does not lead to causation on its own, but there MUST be correlation if there is to be a claim of causation. If you want to claim that X causes Y, you must be able to show that where there's X, there's Y.

      The correlation/causation ranting has obfuscated this simple fact, leading to people buying into the raving of people like He Who Must Not Be Named, who is unable to show even a tiny fraction of percentage correlation between the tens (hundreds?) of millions of video game players and actual acts of real-world violence committed, yet has convinced many people that some form of causative link exists.

      isn't really nice when you're doing it with money and a research staff/equipment that don't belong to you.

      Studies like the one performed is probably one of the fastest and least expensive ways to collect a number of environmental factors (the original paper reported a "top five") for further study to determine if there is a causative link. Otherwise, what you have scientists do? Open up a dictionary and start at "a" and test everything one at a time with a much more rigorous and expensive test for causation?

    (1) Does the article or summary assert causation at any point? No, they don't. Therefore, "correlationisnotcausation" is an entirely irrelevant response here.

    (2) Is correlation the strongest possible result from research like this? Yes, it is. To demonstrate causation you'd need a designed experiement, with babies raised for years in a controlled environment with vinyl to see how many became autistic; experiments like that are not possible.

    (3) As another poster said, "correlationisnotcausation" has become Slashdot shorthand for "I choose to ignore all of your scientific evidence". Compare to: "Evolution has not been proved, it's only a theory."
