Evidence and muddling through
The difference is that 'muddling through' is a strategy bound to evidence, evaluation, and adaptation. In policy as in business entreprise, grand visions and definitive models, like 'settled science', call for commitment and resist new enquiry or contrary fact.
"Prof Lindblom contrasted what he called the ‘root’ method of decision-making with the ‘branch’ approach. The root method required comprehensive evaluation of options in the light of defined objectives. The branch method involved building out, step-by-step and by small degrees, from the current situation. Prof Lindblom claimed ‘the root method is in fact not usable for complex policy questions’. The practical man must follow the branch approach – the science of muddling through." Extract from John Kay in the Financial Times
