First, according to the positivistic approach, true or correct knowledge only comes when the observer separates him or her self from that which is being studied. You undoubtedly came across this idea in your methods class: the researcher must take an objective stand in order to safeguard against bias. Second, personal emotions must be set aside in the pursuit of pure knowledge. Third, no personal ethics or values must come into the research. Social science is to be value-free, not passing judgment or trying to impose values on others. And, fourth, knowledge progresses through cumulation and adversarial debate.
