Oxford psychologists in an Anglican country did some surveys and have recommendations for Catholics: People who recall being absolved of their sins are more likely to donate money to the church, they write Religion, Brain and Behavior.
Academics from Royal Holloway and the University of Oxford assigned participants two memory tasks. In the first, they were asked to privately recall a sin that they had committed in the past, while in the second, they recalled attending confession for this sin or imagined doing so, if they had not confessed in reality.
Each participant was also given an opportunity to donate to a local Catholic church by placing some money in an envelope. For some participants, this donation was collected before they recalled being absolved of the sin, whereas for others the donation was collected afterward.
The results showed that recalling (or imagining) absolution strongly increased church donations, with the effect more pronounced in participants who believed in divine judgment and engaged in religious activities such as reading the bible or praying.
Dr Ryan McKay from the Department of Psychology at Royal Holloway said, "Recent evidence has suggested that people are more likely to behave prosocially, such as helping, sharing, donating, co-operating and volunteering, when they feel guilty. This raises the question of whether religious rituals of absolution, in which people are absolved of their sins and released from guilt, would actually make people less prosocial.
"However, the results of our study suggest the opposite - that 'releasing' people from their sin has a positive prosocial effect. This indicates that the Catholic ritual of confession is an effective means of promoting commitment to the church"
Many other religions feature the concept of absolution in varying forms, such as Istighfar in Islam. The researchers are now keen to see if similar results would be seen beyond Catholicism. The research is part of a wider project on 'Ritual, Community and Conflict' supported by the Economic and Social Research Council (ESRC).
