Self-affirmation may be an effective tool to reduce prejudice and discrimination against minority groups. Its hypothesised mechanism is that prejudice is a defensive act that can be reduced by reinforcing a positive image of the self. Such a reinforced self-image is meant to weaken perceived threat to one’s social identity that may be posed by minority groups, such as Muslims in majority Christian countries.

 

To address mixed evidence for the effectiveness of self-affirmation across the literature, Alnajjar et al. (2024) aim to elucidate conditions under which self-affirmation may reduce prejudice and discrimination. Whether self-affirmation has the desired effect may be moderated by an individual’s internal representation of secularism. That is, as a reaction to self-affirmation, people may flexibly endorse their feelings towards secularism to either reduce prejudice, or maintain and justify it.

 

The authors present a study design (including a three-way mixed ANOVA) in which they plan to self-affirm French participants (N=600) with differing internal representations of secularism. Across three self-affirmation conditions (i.e., self-affirmation on a threat-related value, a threat-unrelated value, and no self-affirmation), the authors will assess the effect of self-affirmation on prejudice towards Muslims. They will also assess their participants’ attitudes towards Christians and Muslims, to distinguish whether prejudice is specifically targeted against Muslims, rather than religious groups in general. In addition, the study setup considers desirability concerns and it employs multiple manipulation checks to increase robustness of results.

 

With this proposed plan, the manuscript presents a persuasive rationale that it taps into the wider concept of ‘ideological malleability’ that could be the underlying mechanism to explain a moderating effect of secularism on the effectiveness of self-affirmation in this French sample. By considering nuances of public opinion towards secularism in France specifically, the authors have identified a unique opportunity to investigate ideological malleability, which can be challenging to conceive and directly measure.

 

The Stage 1 manuscript was evaluated by two experts who performed in-depth peer review across multiple rounds of revisions. The authors were very responsive in editing their manuscript based on the reviewers’ comments and dedicated much effort to increasing clarity and interpretability of their power analyses. Consequently, the revised manuscript was judged to meet the Stage 1 criteria and was awarded in-principle acceptance (IPA).
