The Significance of Unwillingness to be Tested

Abstract

Sixty-five teachers were given the Thorndike College entrance examination, Part I, and told they could sign their names or not as they preferred. Thirty-nine signed their names, 26 did not. The average score of signed papers was 100, of the unsigned, 75. Only four of the 26 unsigned papers equalled or excelled the average of the signed group. Only five of the 39 signed papers were so low or lower than the average of the unsigned tests. From Psych Bulletin 19:11:00865. (PsycInfo Database Record (c) 2024 APA, all rights reserved)
