A lack of research into possible cultural differences in understanding and using deception inspired this study. The research examined the differences in attitudes, beliefs, and personal behaviors with regards to deceptive behaviors in five different ethnic/cultural groups: White/Caucasian, Black/African-American, Latino/Hispanic/Non-White, Asian/Asian-American, and Middle-Eastern. The participants were administered questionnaires with a demographic measure, questions about their beliefs about their abilities and beliefs about discovering deceptive behaviors, their personal beliefs in what could be most effective in attempting to hide their own lying, and three different outcome measures for deception, ethnic belongingness and personality. The results of the study highlighted the need for developing clearer methods for measuring differences in deceptiveness among different ethnic/cultural groups. Significant differences between ethnicities/cultures were found on their deceptiveness scores on the Balanced Inventory of Desirable Responding, suggesting that use of deception does vary between different ethnicities/cultures. On the surface, there appears to be agreement among most groups about what clues they would use to detect someone else's deception (decreased eye contact, nervous facial expression, speech pauses, contradictory statements) but there do appear to be subtle differences between the groups on how much they focus on verbal (White, Asian) and physical clues (Black, Latino, Middle-Eastern). Neither age nor income were found to be correlated with deceptiveness. Testing personality dimensions against lie-scores revealed that three of the four personality dimensions in this sample showed statistically significant results – neuroticism, lying, and psychoticism. These results suggest that a connection between personality styles and deceptiveness exist and might be useful in determining a person's likelihood of being deceptive. The analysis did not reveal a significant relationship between gender and scores on either the impression management component or the self-deceptive enhancement component of the deceptiveness scale. No connection was found between a person's level of ethnic belongingness and their deceptiveness.
