Abstract: Although several scholars acknowledge the existence of tears of joy, there is little systematic theoretical or empirical evidence on how positive tears are experienced, what elicits them, what actions or impulses they motivate in the crier, how they differ from tears of sadness or distress and whether there are different types. We systematically investigated these issues and drafted a first taxonomic model of positive tears. Drawing on more than 1500 reports of positive tears and including 13124 participants from 40 diverse countries and 24 languages, the studies employed a strong mixture of quantitative and qualitative techniques. The final results showed evidence of the occurrence of positive tears and found four qualitatively different types and profiles that we termed achievement, beauty, affection, and amusement tears. Achievement tears are often shed in contexts of extraordinary performance or when someone overcomes an obstacle and often include feelings of pride. Beauty tears occur commonly in situations of overwhelming elegance or beauty, including nature, music or visual arts, and feature feelings of awe or experiencing chills. Affectionate tears are often experienced in situations including unexpected kindness or exceptional love such as wedding ceremonies or reunions and often feature feelings of warmth, increased communality, and feeling touched or compassionate. Finally, amusement tears are shed when something especially funny occurs and include feelings of amusement or lightness and the inclination to laugh or giggle. We also investigated cross-cultural and inter-individual differences with regard to these categories and discuss limitations and implications of our taxonomy of positive tears.
