Ethical decisions are contextualized in the dialectic of a multidimensional system, including situation, setting, culture, and generation. There may be further gaps between the ethical considerations of professionals and folk values. The experience of promoting equal opportunities in Hong Kong illustrates some of these challenges. Whereas the rule of law under a Western legal system advocates human rights, the traditional emphasis on harmony and preference for balancing in conflict resolution underlie the gaps in the interpretation of these ideals. The case of the Hong Kong secondary school places allocation system highlights the conflicting perspectives of law, gender stereotypes, psychological knowledge, as well as ethical principles of justice and fairness in promoting equal opportunities in educational assessment and placement. The cultural perspective highlighted in this case illustrates the complex contexts of ethical decisions.
