Epistemic literacy is the ability to critically evaluate, question, and understand the sources, credibility, and context of information. In cybersecurity, this skill is vital for distinguishing trustworthy data from misinformation or malicious content. Practicing epistemic literacy helps individuals and organizations recognize biases, assess the reliability of digital sources, and make informed decisions. As cyber threats often exploit misinformation and social engineering, strong epistemic literacy is a key defense against manipulation, phishing, and disinformation campaigns. Developing this skill involves continuous learning and skepticism towards unverified or sensational claims encountered online.
