This approach urges individuals to recognise and believe they possess unalienable rights which have been made judicable in international human rights instruments. Assessments and audits of economic and social rights have been undertaken in an attempt to describe patterns of poverty. This can be useful as a tool to systematically assess entitlements, particularly in relation to basic needs such as potable water, housing and nutrition. However, often individual rights conflict with broader collective ones and seeking to meet one sub-set of a community's rights can produce perverse effects and inequalities in a wider context.
