“…In 1920, Edward Thorndike (1920) observed that military commanding officers’ ratings of subordinates’ performance changed after they interacted with their subordinates. More recently, the halo effect has been documented in a variety of contexts such as ratings of students (e.g., Malouff & Thorsteinsson, 2016), teachers (e.g., Keeley et al, 2013), employees (e.g., Viswesvaran et al, 2005), managers (e.g., Mathisen et al, 2011), politicians (e.g., Babad et al, 2012), online reviewers (e.g., Ozanne et al, 2019), and multiattribute objects such as websites (Kwak et al, 2019), resulting in biased perceptions of characteristics like success, competence, intelligence, and expertise. Given the apparent pervasiveness of this interpersonal bias, evaluation of the therapeutic encounter may also be susceptible.…”
