Summary/Abstract: In line with the conjunction rule, the probability of more events co-occurring is always less than the chance of either one occurring alone. Violation of this principle represents one of the most robust cognitive biases. While among individual choices the presence of conjunction fallacy is particularly frequent, recent findings suggest that in cases of social interaction—consultation of solutions—the proportion of incorrect automatic answers decreases. Social influence on the level of cognitive reflection, an ability to suppress automatic intuitive responses and to engage in analytical thinking, has not been sufficiently studied yet. Therefore, enriching the design of baseline research focused on solutions to the Linda problem "solo" and after consultation, we also analyzed the answers in the Cognitive reflection test, and compared individual and group results. The findings of our experimental study (N = 210) are inconsistent with the assumption of "the more heads, the more rationality". We identified the following predictors of intuitive responses: subjective confidence, balanced discussion and demonstration of the correct solution. Main implications concern ecological validity within research of cognitive errors and practical recommendations for decision-making situations of groups and their members in personal and professional life.
