Researcher: The rate of psychological problems is higher among children of divorced parents than among other children  But it would be a mistake to conclude that these problems are caused by the difficulty the children have adjusting to divorce
It is just as reasonable to infer that certain behaviors that increase the likelihood of divorce -- hostility, distrust, lack of empathy -- are learned by children from their parents, and that it is these learned behaviors, rather than the difficulty of adjusting to divorce, that cause the children' s psychological problems
It is cited as an established finding for which the argument proposes an explanation.
