My personal experience is that the very best managers use "asking questions" as their main management tool as this is effective to reveal all aspects of a situation and get employees to understand and support the decisions that follow.

Weak managers like to "take decisions" as a display of their value as a manager. This value elevation is undermined by old experienced employees who can point out bad decisions or that the manager doesn't understand the consequences of the decisions, i.e. a fear of being "exposed". Weak managers fear anything that makes them seem weak, like asking questions.
