For knowledge to become actionable, it has to be trusted.
It has to be believed as being true!

In order to cooperate with somebody, you need to trust that person.

But trusting a person is far more complicated than believing that a piece of information is true!

Evaluating a piece of knowledge is a uni-dimensional business. That piece of knowledge either corresponds with (what is considered to be) reality – it is ‘true’, or it doesn’t. Hence it is false.
And it’s only after you have satisfied yourself about an information being true that you may start to ‘own’ it. To act upon it.

When it comes to trusting a person, you are confronted with a bi-dimensional endeavor. Which makes it a real problem.
In order to be able to cooperate with somebody, you need to be satisfied on two accounts.
That that person is qualified enough for the business at hand AND that that person ‘means well’.

Not that simple, is it?
