A reconstruction of the original figures at age twenty-two

 





Appendix 1 to: "Television violence is fully harmless"
Previous
  The research group conducting the Children in the Community Study does not give much information about the figures of aggressive behavior at age twenty-two. Looking at the clues they offer, we guess that those figures may have looked like those in Table A below:
 
poverty aggressive   daily hours television   total total
  behavior   less than 1   1 to 3   3 or more   at 22 at 16

+ +   2     11     19     32   16  
+ -   6     10     17     33   49  
  subtotal:     8     21     36     65   65

- +   5     97     64     166   143  
- -   75     268     133     476   499  
  subtotal:     80     365     197     642   642

  total:     88     386     233     707   707
  Table A: Reconstructed data describing the relation between low family income (poverty), daily hours of television at age fourteen and aggressive behavior at age twenty two
  If we compute these figures back to age sixteen, the data of the resulting table will conform to the statistical parameters described in the Science article (see Table 5 in the main text). The real data may have looked like those in Table B below (see Appendix 2). Comparing the figures of Tables A and B we find a rise in aggressive behavior, mainly among youths from "low income families". This clearly can be attributed to the higher risk of this group of adolescents of falling into "aggressive behavior" over time — i.e. between the age of sixteen and twenty-two — due to circumstances related to poverty. The New York research group surely can not have failed to notice this.
