Summary
The strongest evidence indicates that some rituals can causally improve cooperation by synchronizing behavior, increasing physiological arousal, strengthening shared identity, and signaling commitment. Field and laboratory studies report greater cooperation after synchronized or complementary activity, although these effects are specific to particular tasks and settings rather than proof that rituals generally make groups cooperative.
- In a large naturalistic experiment, synchrony and physiological arousal predicted tighter clustering and more cooperation in a free-rider dilemma; their combination produced especially strong effects.
- A laboratory drumming study found that both synchronous and complementary coordination increased public-good contributions, partly through stronger feelings of belonging to the same group.
- Research on naturally occurring rituals found that synchronous movements were more likely to enhance prosocial attitudes toward fellow participants.
Deeper Insight
A more skeptical interpretation is that rituals do not simply produce generalized cooperation. They may chiefly identify insiders, reward conformity, and redirect benefits toward the group at the expense of outsiders or independent judgment. Some observed associations may also reflect self-selection, existing group norms, or the special features of short experimental tasks.
- Rituals may increase in-group solidarity while also encouraging conformity, groupthink, and reduced productive dissent; synchrony therefore involves a cultural-evolutionary trade-off.
- Children who participated in rituals showed increased in-group displays and out-group monitoring, suggesting that ritual bonding can sharpen social boundaries rather than produce universal prosociality.
- Higher cooperation among religious ritual practitioners may reflect selection into groups, group norms, or costly commitment signals, not ritual performance alone.
