The relationship norms behind the needs also affect the sense of responsibility. The types of relationships are mainly classified as exchange relationships, in which people are expecting a reasonable privilege or benefit in return for offering aid; and communal relationships, where those giving assistance are wholeheartedly and generously taking care of those in need without any expectation of reciprocation. According to research, people are more likely to refuse to aid when encountering needs associated with exchange relationships rather than needs with communal relationships. As such, Karen Page Winterich and Yinlong Zhang recommended that charitable organizations in high power distance countries should stress the significance of uncontrollable needs or salient communal relationship norms, through which the populace are more easily motivated to make a difference on social inequality.
