Пилотное исследование связей черт личности с решением дилеммы в условиях социального взаимодействия
In the context of social interaction, the decision-making process becomes more complex due to the need to account for personality traits and the decisions of other group members. This pilot study aims to investigate the link between personality traits and choice in an iterated Prisoner's Dilemma before and after participants' social interaction. The study involved 108 individuals (82 women, 26 men) aged 18 to 26 years. The Big Five Inventory-2 and the Short Dark Tetrad questionnaires were used, along with a multi-stage gaming procedure involving rounds of the dilemma both before and after social interaction. The results showed a significant decrease in the proportion of cooperative decisions after social interaction (from 30.56% to 17.59%). Various correlations between personality traits and cooperation were identified at different stages: before interaction, cooperation was associated with emotional instability and Dark Tetrad traits, while after interaction it was linked to extraversion, responsibility, and industriousness. The obtained data are explained by the influence of fear of negative evaluation and increased social control within the group, highlighting the importance of considering social context in the study of decision-making.
