How can we trust a robot?.

Trust is essential to cooperation, which produces positive-sum outcomes that strengthen society and benefit its individual members.
Individual utility maximization tends to exploit vulnerabilities, eliminating trust, preventing cooperation, and leading to negative-sum outcomes that weaken society.
Social norms, including morality and ethics, are a society's way of encouraging trustworthiness and positive-sum interactions among its individual members, and discouraging negative-sum exploitation.
To be accepted, and to strengthen our society rather than weaken it, robots must show they are worthy of trust according to the social norms of our society.
