Artificial intelligence is becoming a potential outgroup of humans, which, according to social identity theory, may make humanity more salient. To explore how identification with humankind correlates to being exposed to artificial intelligence, we developed an AI Experience Questionnaire to measure this relationship and demonstrated that AI experience positively predicted human identity (Study 1a, N = 806). This correlation held when controlling for AI threats, educational level, international mobility experience, gender, and age (Study 2, N = 981, Mage = 27.55 ± 6.74; 448 males, 533 females). Study 1a also demonstrated that AI awareness—consisting of perceived anthropomorphism and perceived proximity—mediated the relationship between AI experience and human identity. This mediation model was replicated half a year later (Study 1b, N = 886). Moreover, a moderation analysis demonstrated that for both Easterners and Westerners, the correlation between AI experience and human identity was significantly positive; however, Western culture amplified the correlation (Study 3; N = 177, Mage = 32.35 ± 10.99; 90 Easterners, 87 Westerners). To conclude, persons with more AI experience may be more inclined to perceive AI as an outgroup of humans, and therefore AI experience positively predicts identification with humankind.
