Feedback from a disinterested observer can be a powerful stimulus for change. In our everyday lives the new mirror in the bathroom can act as the disinterested observer reminding us of progress (or lack of progress) in the fight against middle‐aged flab. Similarly there are few more salutory experiences than the first time we see ourselves on film or in a video‐taped training excercise. “Do I really act like that?” we might ask incredulously, but rapidly there is acceptance that the answer is “probably yes”, followed by a resolve to do something about that mannerism that had been so disturbing to witness.
