- No it isn't. What is is saying is that there appears to be a correlation
- between hams and higher rates of cancer mortality. Write this 1000 times:
- "Correlation does not beget causation." Many people innocently confuse
- correlation with causation; the media and certain groups do it agressively
- intentionally. For example, there is a correlation between those people
- who have ham licenses and those who own handi-talkies. One cannot
- conclude that having a ham license causes HT ownership.
-
- Analyzing cancer excess mortality is notoriously error-prone. Small
- samples, as in the above case are famous for generating false correlations
- that are discredited with more extensive study. Indeed quite often
- large scale studies frequently directly contradict the results of small
- studies. Being a nuke, I have more than a passing interest in this.
- I'd suggest taking what he said for what it is, a correlation that may
- or may not have a basis and then keep an ear to the ground for further
- developments.
