Including both of those factors can entail a lot of other issues that can affect the results of the study and purposely omitting them definitely is creating a fairer environment for observation.
I think the authors of the original study should have kept those data, and used them to show that the key element (as in, highest statistical correlation) is stability. That children who live with the same family all their lives, do better than children who get shaken around, regardless of the number or genders of the adults in the family. Or something similar.
I believe something like that would have been less susceptible to attacks. Discarding data really does look bad.
Also, I have to ask, what is this "household head"? Like, for tax purposes? It really matters whether the child is biologically related to the higher income earner or the other adult?
