- Alice Stewart has pulled another coup. The normal time lag for responses to
- journal articles to hit the streets is about 4 months. By releasing her
- "results" 4 months before publication, she has an 8-month jump on
- critical review.
-
- If her past practice can be used as an indicator, she will take a
- population with lower than normal cancer rates, divide it into many
- subsets, and report those with "higher than expected" values as
- meaningful...all without consideration of the total number of trials,
- and without consideration of all those subsets with lower than "normal"
- results.
-
- One can, of course, do the same thing with a matrix of random numbers.
- The next step is (and has been in her earlier Hanford work) to divide
- the "effect" by the dose for the usually small population to get a
- dose-response. The smaller the dose, the larger the inferred
- dose-response; it would, of course, become very large as the dose
- approached zero.
-
- Sadly, this practice is rather common among those who have a priori
- answers, and only grope around for facts to support them. My view is that
- they find only statistical sheep in imaginary wolves' clothing. The sad
- thing is that the press and the public are taken in by them. The
- charges, however ridiculous, stick; the scientific critiques, however
- valid, rarely see the light of day.
-
- All in all, it is reminiscent of the words of Samuel Johnson, who said,
- "That fellow seems to me to possess but one idea, and that is a wrong one."
