“…However, there are several reasons to be cautious about their unqualified promotion. Crucially, a number of other studies of values affirmation have shown more nuanced effects or none at all (Borman, Grigg, & Hanselman, 2016; Bowen, Wegmann, & Webber, 2013; Bratter, Rowley, & Chukhray, 2016; Dee, 2015; Hanselman et al., 2017; Hayes, Zinner, Wise, & Carton, 2019; E. O. Jones & Huey, 2020; Protzko & Aronson, 2016), and indeed some have found evidence of backfire effects for specific groups of students (Bayly & Bumpus, 2020; Brady et al., 2016; Cohen et al., 2006; Dee, 2015; Liu & Huang, 2019; Miyake et al., 2010). These findings may, in part, be due to variations in the implementation of the interventions (Borman, 2017; Easterbrook et al., 2020a), such as using online rather than written exercises (Bayly & Bumpus, 2020), presenting the exercises as part of an external research study rather than something teachers want the students to complete (Protzko & Aronson, 2016), or because the school did not have a sufficiently supportive environment to sustain the effects (Dee, 2015).…”
