The problem is not one of qualifications, but of motivation and trust. Even if you genuinely believe the organization before you is filled with nothing but the brightest individuals in the world, leagues beyond your understanding in their field, it means absolutely nothing if you don't trust them. In fact it would mean less than nothing, as there's nothing scarier than a clever individual with "impaired" ethical values.

Trust is difficult to earn, and easily lost. And we live in a society where, for most, trust is gone. The way to get it back is through extreme transparency and coming from a point of view of understanding this distrust.

Trust isn’t so easily lost when you understand the lack of certainty in this world.

So then, who benefits from offering certainty, if it’s more or less impossible to obtain?

Everyone does. That's why its such a popular tactic, but trust is so hard. That is the reason for transparency.
