action drives belief

Douglas Reeves says that “action drives belief,” not the other way around. He contends that it’s usually difficult to see the benefits of something before we do it because it’s too abstract. We have to start doing it - and thus turn the conceptual into something more concrete - before we actually see the benefits and buy in. This is why, for example, many school districts require educators to be in professional learning communities (PLCs). At the beginning, most educators aren’t clear what the benefits of PLCs will be to them. Over time, however, if the initiative is done well (and, unfortunately, in education that’s a big if), the idea is that educators will start seeing - through their ongoing PLC activities - the benefits of belonging to such a group. Does action drive belief or does belief drive action?
