Data from: Deliberation favours social efficiency by making people disregard their relative shares: evidence from USA and India

Groups make decisions on both the production and the distribution of
resources. These decisions typically involve a tension between increasing
the total level of group resources (i.e. social efficiency) and
distributing these resources among group members (i.e. individuals'
relative shares). This is the case because the redistribution process may
destroy part of the resources, thus resulting in socially inefficient
allocations. Here we apply a dual-process approach to understand the
cognitive underpinnings of this fundamental tension. We conducted a set of
experiments to examine the extent to which different allocation decisions
respond to intuition or deliberation. In a newly developed approach, we
assess intuition and deliberation at both the trait level (using the
Cognitive Reflection Test, henceforth CRT) and the state level (through
the experimental manipulation of response times). To test for robustness,
experiments were conducted in two countries: the USA and India. Despite
absolute-level differences across countries, in both locations we show
that: (i) time pressure and low CRT scores are associated with
individuals' concerns for their relative shares and (ii) time delay
and high CRT scores are associated with individuals' concerns for
social efficiency. These findings demonstrate that deliberation favours
social efficiency by overriding individuals' intuitive tendency to
focus on relative shares.
