Genuinely moral partners signal higher reliability than strategically moral ones.

Evidence

To answer the challenge, it is necessary to consider not only the perspective of an individual wanting to be chosen as a partner, but also that of an individual or a group deciding with whom to cooperate. This is an important decision that may secure or jeopardize the success of cooperation. Hence, just as there should have been selective pressure to behave so as to be seen as a reliable partner, there should have been selective pressure to develop and invest adequate cognitive resources in recognizing truly reliable partners. Imagine that you have the choice between two possible partners, call them Bob and Ann, both of whom have, as far as you know, been reliable partners in cooperation in the past. Bob respects the interests of others for the reason and to the extent that it is in his interest to do so. Ann respects the interests of others because she values doing so per se. In other words, she has moral motivations. As a result, in circumstances where it might be advantageous for your partner to cheat, Ann is less likely to do so than Bob. This, everything else being equal, makes Ann a more reliable and hence a more desirable partner than Bob. — Nicolas Baumard, A mutualistic approach to morality, 59
