Confirmation bias is a universal mental shortcut that leads us to favor information confirming our pre-existing beliefs while neglecting contradictory evidence, which can affect the quality of our decisions, particularly among healthcare providers.

This concept is a fundamental pillar of cognitive and behavioral psychology. It has been extensively documented since the pioneering work of Peter Wason in the 1960s on the selection task, which demonstrated this natural tendency to seek confirmation rather than falsification (experimental study). Scientific literature, notably meta-analyses on clinical decision-making, confirms that healthcare professionals, despite their expertise, are not exempt from these heuristic biases. These mechanisms are considered energy-saving strategies for the brain, effective in emergencies but risky for complex analysis. The assertion that this is a universal phenomenon and not specific to healthcare providers is also supported by numerous studies in social psychology. There is no exaggeration here; the creator accurately popularizes a cognitive mechanism that is robust and widely recognized in neuroscience research.
