In this work, the technology of personality structure assessment using the Five-Factor Personality Questionnaire (5PFQ), adapted for the Russian sample, has been applied to the generative neural network GPT-3.5 implemented in the ChatGPT product. It has been found that the “personality” of the generative neural network ChatGPT exhibits characteristics of a moderate extrovert with low sociability, low behavior control with some level of irresponsibility, moderate emotional sensitivity, unrealistic and impractical outlook on life with very high curiosity. Comparing the survey results of ChatGPT using the 5PFQ with normative values for men and women allowed us to establish the correspondence between the “personality” of ChatGPT and the social cluster of middle-aged Russians. © The Author(s), under exclusive license to Springer Nature Switzerland AG 2024.
