By converting personal trust into system trust, the process of learning is rendered easier, but control is made more difficult. Thus, typically, trust in money arises in, as it were, an automatically learned fashion, whereby the person trusting realizes his dependence on the functioning of a highly complex system which he cannot see through, although in principle it can be seen through. The person trusting knows he is unable to make corrections; he thus feels himself exposed to unforeseeable circumstances, but nevertheless has to continue trusting as though under compulsion to do so.
