A diverse array of perspectives was captured by reaching out to participants within this system using purposive sampling. To assess consensus among cultural norms and ascertain the viability of merging them into a cohesive belief system, the formal cultural consensus model was employed. This model enables in comprehending response variations and determining the prevalence of shared beliefs among Karuthakolomban collectors.
