I think that ‘to switch on brain’ is generally good idea but we should remember that if something is ‘switched on’ it consumes energy. People or other systems always tend to a minimal energy expenditure / maximal result balance. It’s an immanent property of a natural system. In this way, we cannot ‘switch on brain’ every time we need to make a decision because we don’t have enough energy to keep the brain system on all the time.

When we use something finished, for example, expert’s opinion, we try to reduce the consumption of energy – not because we are lazy but because we have limited energy resource and we need to set priorities. I think that the main reason to use someone’s help is the lack of energy – not the lack of knowledge or experience.

To keep the right energy balance we must be very careful when we choose our experts and decisions for delegation – and that’s all. We cannot work out thoroughly 100% of decisions, so we need to select right people who can give right advices and keep the control functions, for example, to analyze the results after we followed the advices of expert, or to get second opinion at times. We also need to make very important decisions by ourselves and don’t try to delegate them (or blindly follow someone’s advise) because the price of a mistake is high.

To sum up, I think that the real question is not ‘to listen or not to listen experts’ but ‘to whom do we listen’ and ‘what kind of decisions we can delegate’.
