What was done
Researchers collected published interviews of Carnegie Hero Medal Recipients (CHMRs)—extreme altruists who risked their lives to save others. Independent participants rated the statements to evaluate whether the decision to act was intuitive or deliberative. Ratings of CHMR testimonies were compared against control statements of intuitive and deliberative decision-making, including a subset analysis of rescue scenarios where individuals had sufficient time to reflect. Findings were also evaluated using automated text-analysis software.
What was found
The abstract reports no numerical values, effect sizes, or test statistics. Statements from CHMRs were reported to be overwhelmingly dominated by intuition, were significantly more intuitive than deliberative control statements, and did not differ significantly from intuitive control statements. This pattern held in scenarios where heroes had time to deliberate before acting. Text-analysis software yielded concordant results.
Why it matters
These findings suggest that high-stakes, life-risking altruistic behavior operates predominantly through fast, automatic intuition rather than deliberate, calculated reasoning overcoming self-preservation.
Limits
The abstract does not state the number of CHMR testimonies, control texts, or participant raters. The study relies on retrospective, public post-event accounts, which are subject to recall bias, narrative reconstruction, and media framing, rather than real-time measurement of cognitive processing during crises.
