During the recent crisis I have noticed a great number of big decisions being made, many of them with significant or life changing implications.  Very often we hear and expect that key decisions have been taken based on the scientific and medical evidence.  However when we look further afield we can see that decisions are also having to be made without the luxury of previous experience, sometimes even despite of expert advice.  If all decisions could be made solely on evidence or experience then we would not need leaders – just process managers.  Complex problems may even require the courage to make initial decisions with no information, in order to probe effect and enable further decision making.  Therefore a leader should utilise all support available but accept that sometimes decisions will have to be made based on limited information, so will need judgement and intuition.
