      Edgar,
       
      An increase in the incidence of autism and ADHD is largely due to improved, modern reporting... but a large component could still also be because of your theory concerning TV.  Many genes, especially those underlying behavior, require a certain environment to be expressed or inactivated.  Research on extreme anti-social behavior, the "psychopath," strongly suggests that certain alleles... and an abusive early childhood (there's a narrow window) are required in order for the pathelogically anti-social behavior to be expressed.  Twins raised in the same abusive environment, but without the "required" (suspected) alleles do not become psychopaths.  I can easily imagine the same sort of thing with autism, ADHD and an environment with excessive TV.

      Sonny,

      There could certainly be genetic components conveying a sensitivity
      to the effect of TV as you suggest, but TV is likely by far the
      primary cause of Autism and ADD-ADHD. Otherwise we would have to
      explain why either these genes arose widely only recently, or
      conversely why the incidence of autism pre-TV was so low.

        I agree with your criticism of the word "abnormal."  My limiting its use to a purely... well, "mathematical statement," and adding, "In most other senses of 'norm,' however, it is not 'abnormal,'" was intended to reflect your well-stated view.

        Edgar,
         
        I agree that the term "normal" can be used to describe human behavior... if it is carefully defined.  I also agree that descriptions of individuals along lines of differences from statistical norms should be taken as such and not used for sociopolitical reasons.  Homosexuality, for instance, is not the statistical norm for the human population, so in this sense it is "abnormal."  In most other senses of "norm," however, it is not "abnormal." 
         
        RKS:
        That doesn't quite wash ~ there are more individuals identifying with a homosexual lifestyle than there are redheads.  Does that mean that redheads are 'abnormal'? (between 1 and 2% of the population are redheads according to Wikipedia).
         
        One is probably better to stick with 'minority trait' or some other equally sexy label than trying to sanitise an emotionally loaded term such as 'abnormal'.
         
        Kind Regards
        Robert Karl Stonjek
