The present study explored the relationship between religiosity and work conscience with a tendency to administrative and financial corruption. A sample of 400 participants was selected through the systematic sampling method. The data was collected by questionnaire, the validity of which was determined by face validity, and the reliability was checked by internal consistency using Cronbach's alpha method. The analytical results also showed that work conscience and religiosity have a positive and significant impact on the tendency to administrative and financial corruption. Moreover, the demographic variables of occupation, social class, and income are significantly associated with the tendency to corruption. Explaining the dependent variable by the sum of independent variables indicated that work conscience (reliability), income, social class, and ethnicity, respectively, are the strongest predictors of the tendency to corruption, which can explain 13.6% of the corruption tendency variance. The findings were compared with similar results, and suggestions were provided to prevent the spread of corruption.
