The objective of the study was to analyze whether the joint impact of the paradigms of self-persuasion and indirect change on attitude changes with respect to sexual diversity was greater than when the self-persuasion paradigm is used alone. The results showed that participants who argued against a certain proposal showed greater attitude changes, though their objective was not to convince themselves but others. This change was greater for those who had argued according to the indirect change paradigm. Finally, the study discusses the importance that these paradigms can have in the deterioration of attitudes toward sexual diversity.
