A question, frequently with a sexual theme, sometimes used with the Keeler Relevant/Irrelevant test in the late 1940s and early 1950s. Leonarde Keeler experimented with the embarrassing personal question, hypothesizing that guilty subjects would not respond to it, remaining instead focused on the relevant questions, while the innocent examinees would produce significant responses in the opposite pattern. The embarrassing personal question did not have widespread use and was not taught at Keeler’s school after 1951.
