Couples Special Interest Group list serve. This post from Scott is too good to let it evaporate off into cyber oblivion.
Marriages are complex.
What I mean by this is that I think, if one looks at what was being studied 25 years ago compared to the ongoing research today, the field has not only gotten more complex, but it's gotten more complex in useful and interesting ways. The nuts and bolts of interaction and such have generated very useful information that I personally feel are, indeed, very widely applicable to the average couple. But I am personally excited that the ship is heading that direction. At least it seems that way to me. I suppose this could be taken as a hypothesis, for which I am hoping we will have a great deal of data for evaluation 10 years from now.
