Power shifts attribution of action from subordinate to power-holder. [causal]
This solution to the motivation problem is backed up by a corresponding solution to the problem of attribution. One needs motives only when action is imputed. In the case of an action motivated by power, the selection, although carried out by both parties, tends to be attributed to the power-holder alone, because the power-subject does not appear to have motives which can be recognized as his own. Admittedly this does not have to be the case. For example, not every exercise of power frees the power-subject from criminal responsibility. A power-code, however, must take account of this tendency to shift attribution and can legalize and formalize it by giving the power-subject, for example, the possibility of being 'officially' compelled and thereby relieving himself of responsibility. In extremely power-specific codes, such as the military, this even occurs without the assistance of the subordinate; the officer takes responsibility for an unclear order.
