This study presents a qualitative investigation of participant responses to a shared values intervention designed to reduce anti-immigrant prejudice by visually presenting overlapping value distributions between ingroups and Pakistani immigrants. The data were derived from the qualitative responses of participants assigned to the experimental condition of a larger study, including 73 individuals from the United Kingdom and 63 from Türkiye, for a total of 136 participants. Participants were exposed to value similarity graphs based on World Values Survey data and asked to provide written reflections. Using abductive thematic analysis, we identified six key themes: (1) Expectation-Reality Discrepancy, (2) Cultural Comparisons and Directional Differences, (3) Interpreting Similarities and Differences, (4) Skepticism and Critical Approach, (5) Positive Emotional Response and Social Connectedness, and (6) Cognitive Processes and Self-Reflection. Results indicate that while many participants expressed surprise and positive reappraisal of intergroup similarities, others emphasized differences or questioned the data's validity. Cross-cultural differences emerged, such as more frequent ethnocentric references in Turkish responses and East-West framing only among UK participants. The findings illustrate the nuanced and varied cognitive and emotional processes triggered by value similarity interventions and highlight the importance of cultural context in shaping responses to prejudice-reduction efforts.
