Conventional animistic beliefs and culture have played a major role in and have influenced the lifestyle of the agrarian society of the Karen ethnic group. Originally, the ethnic production system depended mainly on household labor from their family and kinship systems. Modernity resulted from socio-cultural and economic changes had played a role in these systems, which resulted in animistic rituals and practices to become more advanced by being more flexible. The results from testing the hypotheses to find the relationship between the family and kinship systems and animistic culture of the ethnic group at Tambon Pa Pae, Mae Taeng District, Chiang Mai Province, revealed that types of family (nuclear or extended), inter- or intra-marriage, approval or disapproval of inter-marriage, power in selecting partners, power in selecting residence after marriage, power in making family decisions, and different opinions on heritage did not affect differences in their animistic culture. However, economic and socio-cultural changes as well as changes in conventional settlement patterns resulted in significant differences in their animistic culture. It was noted that most of the sample group still maintained their conventional beliefs, but did not practice them, preferring instead a more advanced animistic culture (pp. 101-106).
