Why so many capable people find it almost impossible to say those three small words, I don't know.

Let me start close to home because this isn't a leadership problem, it's a human one.

Think about the last time you were given directions you didn't quite follow, or instructions at work you didn't fully understand.

Did you ask them to go through it again? Or did you nod, say, yeah, I got it, and work it out later in a small, private panic? Most of us just nod.

Think about the meeting where a word or an idea goes round the table that you don't know and everyone else seems to, in the window, to ask, sorry, what does that mean? Opens for about two seconds and then closes for good and you spend the rest of the meeting hoping nobody turns to you and asks you about the bit you didn't follow.

Or think about your first weeks in any new job where everyone speaks in acronyms you don't have yet and there's a small choice every hour between asking what they mean and looking like you should already know them.

Most of us choose looking like we know and drowning initials for a fortnight or even longer.

It makes you a person who, like the rest of us, would quite like to be seen as capable and as frightened of being caught out.

The mask is just the face we put on when we're worried that the real one isn't enough.

But the higher the stakes and the more people are depending on you, the more that little reflex starts to cost.

Because a leader who can't say, I don't know, doesn't just lose a small moment.
