Sociologists debate the extent to which their research can or should be objective and value-free. Some argue that complete objectivity is impossible since sociologists have personal values that inevitably influence their work. Others believe research should strive for objectivity by following scientific methods and keeping personal values separate. Max Weber proposed that values guide research topics but should not influence data collection or analysis, though they are relevant for interpreting results. More recently, some sociologists argue their research should openly promote certain political values like equality. The relationship between sociologists' work and their sources of funding or career ambitions also raises questions about objectivity versus value-laden research.
