The insistence on finding the WHY is pervasive. Psychoanalysis. Dianetics and Scientology. ITIL and Root Cause Analysis. The belief that one has to get to the bottom of a problem can be blinding. Because it is far from the only way to solve problems. Sometimes it is better to evade the problem, to find another path or to stop creating the problem altogether.
If you face a difficult situation or problem in life, do you need to find the cause of the problem to solve it? Perhaps. Or perhaps not. It depends. There is no ultimate answer to such a question. Maybe you need what you ultimately think you need in order to solve it.
If your car breaks down, smoke and fire erupting from the engine, do you need to find out why the engine broke down? Not if it is an old wreck of a car. It would be cheaper to buy a new one. And not if it is cheaper to replace the engine than spend much time investigating the source of the engine trouble. It all depends. On the business case. Maybe it was an omen that you should start get in shape by riding your bike more often.
The insistence that one must get to the bottom of it can create tunnel vision and lead to endless hours of therapy or auditing or figure-figure why it is this way or that way. At least sometimes it’s better to just give a fuck.
