Is PNI a scientifically valid approach?

As a form of action research, PNI does not seek or claim to be scientifically valid. As PNI practitioners, we are more interested in the question of whether PNI is useful. Does it help communities and organizations get to the places they want to go? Does PNI help people get along better, see the world through each others’ eyes, discover new insights they can use? As a whole the approach has that potential, but whether each individual PNI project fulfills the promise of PNI depends on the way the project is carried out.
