To be fair, there is a challenger. Aephraim Steinberg, a physicist at the University of Toronto suggests that the light that exited the chamber is not the same light that entered the chamber. Too many business leaders are frustrated by the effort to achieve profound organizational change. They feel that they have run smack into a wall of impervium and decide that it simply can't be penetrated. That impervium is the mind's resistance to change.
Light bends easier than minds.
Thanks to the example now set by physicists, change champions have reason to persevere, believing that even in the densest and darkest bureaucracies, they might find light at the end of the tunnel. May not be reproduced for any purposes without full attribution.
