The culture of any country is multi-dimensional in nature. The cultural differences exist everywhere. Caste differences is an intrinsic part of the Indian society. The personality differences may occur due to differences and discrimination among different castes. The present research is an attempt to measure the caste differences in the personality factors like dominance, social boldness and privateness. For this study the two broad categories of caste that is SC and Non-SC was studied. A sample of 600 college students from the age range between 18 and 25 was selected. The SC and Non-SC ratio was 1:1. The 16 PF Questionnaire developed by R. B. Cattell-5th Edition was used to measure dominance, social boldness and privateness. Independent t-test was carried out to analyze the data. The result of the study revealed that there were significant differences between SC and Non-SC on dominance, social boldness and privateness. Non-SC subjects were found to be higher on these three factors.
