Humans make ~35,000 decisions a day, and in cybersecurity the stakes demand accuracy and minimized emotion to avoid costly errors. A qualitative study of third-party vendor risk ratings found that cognitive biases can undermine cybersecurity risk management. Mitigating these biases with more objective, consistent evaluation methods can strengthen effectiveness and resilience.

Cybersecurity professionals face billions of data points each day, driving decision fatigue that erodes precision under breach-level pressure. Grounded in ego-depletion theory, this paper examines how sustained decision-making drains cognitive resources in cyber defense.

The average SOC analyst makes more decisions in a single shift than most people do in a week, and the stakes are existential. Every blinking alert, every incomplete data trail, every ambiguous log entry demands judgment under pressure. And yet, the very tools meant to help, dashboards, threat feeds, SIEMs, often flood defenders with so much information that they become paralyzed, fatigued, or worse, desensitized.
