Q Methodology is both a technique and a methodology to study (shared) human subjectivity, that is, people’s viewpoints.

It was originally developed by William Stephenson (1902-1989), an Englishman trained in physics (Ph.D., 1926), psychology (Ph.D., 1929) and studied psychometrics with Charles Spearman and Sir Cyril Burt.

As a technique, Q has been used both in clinical settings for assessing individual patients, as well as in research settings to examine how people think about a topic.

As a methodology, Q also posits a way of abductive inquiry into the human mind as operant subjectivity.
