People as Scientific Instruments

Abstract

People are common instruments in the social sciences. They may act as experimenter, receiving and instructing the participants; they may be a stooge, a confederate of the experimenter who is part of the experimental manipulation; they may function as raters of their own personality or that of others; or they may conduct interviews and do observations. In most social scientific research, people are necessary to elicit, record, or measure the phenomena under study. They are an essential instrument in most social science.
