How do people decide to engage in costly acts to demonstrate commitment to a group? And when do such signals genuinely indicate cooperative intent?
In a new paper published in iScience, the LEVYNA team examined whether reliable commitment signaling is driven primarily by intuitive processes or by deliberative cost-benefit reasoning.
Across three experimental studies involving more than 2,200 participants, the researchers found that the answer depends on signal cost and decision context. Under timer pressure, high-cost signals more clearly separated cooperators from selfish individuals, suggesting that intuition may help stabilize costly signaling. However, these signals did not consistently predict later cooperative behaviour.
When participants had more time to deliberate, cooperators were more likely to choose low-cost signals, and these signals more reliable predicted subsequent cooperation in a public goods game.
The findings suggest that reliable commitment signaling depends not simply on cost, but on the interaction between intuitive predispositions and context-sensitive deliberation.
The study contributes to the broader debates on cooperation, signaling theory, and the cognitive foundations of collective behaviour.

In a new study published in Evolutionary Human Sciences, and let by a LEVYNA researcher, we examine a central prediction of secularization theory: that greater material security should be associated with lower religiosity.
Recent article in journal Evolutionary Human Sciences, where LEVYNA members contributed data, asks whether religious denominations accumulate gradually or are generated in rapid bursts associated with specific historical events.
