Mean offspring for smart and dumb Cads
In the table, I present the mean number of children for white men ages 30-59 who have had at least 20 sex partners. I divided them into those with IQs under 100 and those above.
The terms "Alpha" and "Beta" give the former too much credit, so I'm going to use "Cads" and "Dads" instead. We saw in an earlier post that, while Dads have more kids, the gap is narrowing. The table shows that dumb Cads are contributing more kids to the current generation than their more intelligent counterpart.
The number for the dummies may be rising a bit, while falling for the smarter group, but the changes are too small to make anything of them. One factor that complicates the analysis is that small sample sizes forced me to include a wide range of ages, so the extensive overlap across decades hides trends.
