Abstract
We leverage an ongoing randomized controlled trial (RCT) initiated in Summer 2022 to assess whether an intervention designed to strengthen higher-order reasoning skills also shapes children’s social and redistributive preferences. We study the development of trust and reciprocity, redistributive attitudes, inequality aversion, moral reasoning, and fairness ideals. The intervention was delivered from October 2023 to April 2025, spanning two academic years (grades 2–3) in two provinces in Southeast Turkey. It consists of structured classroom activities and materials targeting core components of analytical thinking—fluid reasoning, short-term memory, analytical categorization, and inference skills—with the aim of improving critical thinking and supporting both academic and socioemotional development.
The original RCT includes 132 primary schools (67 treatment, 65 control) in Gaziantep and Şırnak and was registered in January 2025 with primary outcomes focused on cognitive, socio-cognitive, and higher-order thinking skills (Registry no: AEARCTR-0015281). This supplemental registration documents and analyzes newly introduced measures of children’s social development using only the Gaziantep sample, which comprises 84 schools (43 treatment, 41 control). One control school closed after the first year, leaving 43 treatment and 40 control schools for analysis. Şırnak is excluded from the present study due to funding constraints. If these constraints are relaxed by the time of fieldwork (April 2026), Şırnak will be added.
