>Although blacks were overrepresented in the entire sample
>These sample hospitals served a primarily black, low SES area of their respective cities. Thus the results from Marecek and Hardy may differ from those of the other studies.
>Among whites, in contrast, first born children of mothers 20 to 25 scored lower on the average than children of mothers 18 to 19; children of mothers under 18 did not differ from the other groups.
>Marecek also failed to find a difference on the Stanford-Binet by age at first birth among whites.
>In the Marecek study, no difference in intelligence by mother's age at first birth was found for whites.
>These models were developed only for blacks, since the white samples were too small for meaningful analyses
>Belmont el al. found the contribution of maternal age in years to be very small, contributing less than 1 percent of the variance explained in intelligence.
>In general, the results from the three data sets were very similar. The authors' (Belmont et al.) conclusion was that the offspring of teen mothers suffer IQ depression only because of associated social disadvantages and not because of any “immaturity of the mother.”
All these teen mom stats are shitty because it's brown people, having kids young doesn't turn them brown or something
@Ricotta @Terry Well, "idle", that's kinda part of the problem
