Yes, really.
Here. We could have an interesting discussion that relates to our topic. How would one test the hypotheses that compassion and reading comprehension had significant hereditary components? It is hard to conduct properly controlled experiments on humans in a free society, but put that objection aside for the moment. It is also hard to disentangle environmental variables from genetic variables. Adoptive twin studies provide one possibility. Here's another: Suppose we want to investigate the genetic component of compassion. Suppose we have the resources to conduct background checks on prospective parents. We could rank 200 parent pairs for compassion (by, say, neighbors' opinions, by frequency of assault arrests, by charitable giving, etc.). We could then steal 100 babies post-delivery and switch children of compassionate parents into families of abusive parents, and vice versa. Someone who supposes that both environmental and genetic factors contribute to "compassion", however defined, will predict that the switched children will score between the unswitched children of compassionate parents and the unswitched children of abusive parents.
One could probably design an analogous experiment on the genetic and environmental contributions to reading comprehension.
Just how would a compulsively abusive person with limited reading comprehension conduct an argument? Wouldn't such a person be less charitable, less restrained by the possibility that s/he simply misunderstood the argument from the other side than would a compassionate person?
