Values as a guide to research - we can only select areas of study in terms of their value relevance to us
Data collection and hypothesis testing - sociologists must be objective as possible when actually collecting the facts (eg. not asking leading questions, the hypothesis must succeed or fall solely on whether it fits the observed facts)
Values in the interpretation of data - facts need to be set in a theoretical framework to understand their significance. This is influenced by the sociologist's values, which must be stated explicitly
Values and the sociologist as a citizen - sociologists are citizens, they cannot dodge the moral issues their work raises or the uses it is put to by hiding behind 'value freedom'
