Compassionate love: accomplishments and challenges in an emerging scientific/spiritual research field

Psychological qualities of central interest to religion and spirituality, including virtues such as love, are drawing increasing scientific attention. One recent large-scale research initiative funded by Fetzer Institute focused on compassionate love (CL), an other-centred form of love with recognisable analogues in all major faith traditions. We review findings and impacts from 55 peer-reviewed publications generated by 31 projects funded since 2001. We examine major findings, the role in each study of spirituality/religion, and whether the article cited previous CL literature or used CL terminology. Studies varied greatly in how they operationalised CL. Evidence supported numerous antecedents and consequences of CL. Trend analyses indicated that CL terms are increasingly cited in scientific literature. We suggest future directions for CL research, and identify challenges and opportunities likely to generalise to scientific research initiatives in other fields related to religious/spiritual qualities.
