Instinct and magic
While there is undeniable value in getting data to produce facts, some poeple's professional instinct is even more valuable.
Learn to identify who is instinctly good at predicting what colour will be 'in' next year or which partner will cause trouble, and resist the urge to ask how they know: the result would be a convoluted, hesitant, unconvincing attempt, full of holes and easy to take apart - making them look like fools and discrediting their prediction. After all, it's impossible to see (much less appreciate) the magic once you know the mundane trick behind it.
Good leaders won't try to understand: they too, trust their instincts.
