See the prior post (below) for more information on the National Marriage Project Report that Galena Rhoades and I authored that was released yesterday.
I want to make you aware of a couple of pieces we've written on the important issue of "selection effects." You'll often hear social scientists talk about this subject when they discuss or critique the type of findings we present in the Before I Do report. The subject is important because it revolves around the degree to which scientists believe that some experiences in life are causally related to outcomes in life.
So, you have a couple of options, if you want to read more on this subject.
For a briefer (about 2.5 pages) take, linked directly to the NMP release, check out what we just posted at the Institute for Family Studies website: Selection Effects and Personal Choice
For a longer (about 4 pages), more general take, with similar observations but also a deeper set of questions about the problems of free will in science, see this one: Selection Effects: Social Science and Personal Choices
If you like going deeper on such issues, there you go.
