The first chapter does the usual business of introducing the book. I was looking or hoping for something a little less busy and a bit more integrative that we might sink our teeth into. It would be interesting to consider what key principles (rather than methods) are common and which are contested. For instance, causality, even from the perspective of an ethnocentric adherent of RCTs, seems worth exploring or interrogating. I suspect various chapters may address this, but there doesn’t seem to be enough here to launch a useful discussion.
I hope somebody might prove me wrong;-)
