Innumeracy is the inability to understand, interpret, or work with numbers and basic mathematical concepts. In cybersecurity, innumeracy can lead to poor risk assessment, misunderstanding of security metrics, and susceptibility to scams that exploit numerical confusion. For instance, users may misjudge the likelihood of a cyberattack or fail to recognize the significance of password strength requirements. This lack of numerical literacy can hinder effective decision-making, making individuals and organizations more vulnerable to threats. Addressing innumeracy through education and clear communication is essential for improving overall cybersecurity awareness and reducing risk.
