Business people and politicians do not quite understand this and tend to evaluate decisions by the rigour of the process that produces them, rather than by the rigour with which you evaluate their consequences. To them, the use of reason ‘looks scientific’, even if it is being used in the wrong place. After all, should we refuse to use antibiotics, X-rays, microwave ovens or pacemakers because the scientific discoveries which led to their creation were the product of lucky accidents?
