Just culture

Sidney Dekker's framework for evaluating a human contribution to a failure by asking whether the system made the correct action clear and achievable, rather than by asking only whether a person's action was, in hindsight, the wrong one; distinguishes genuine negligence from a person who followed a flawed procedure, an ambiguous interface, or incomplete information correctly. In practice, this evaluation happens under real pressure to reach a fast, liability-limiting conclusion, especially after a workplace injury; holding the just culture question honestly, rather than assigning blame quickly to close the matter, is itself part of the engineering judgment this topic builds.

The principle that honest mistakes made inside a flawed system are learning opportunities rather than punishable offenses, while genuine recklessness or malice is a separate and rare matter. The line is drawn on what the person knew and faced at the time, not on how the result turned out, which is what makes blamelessness workable and guards against outcome bias.

An investigation practice, used across aviation, healthcare, and increasingly industrial safety, that distinguishes honest human error (examined for its system-level causes, not punished) from reckless or willful violation (which carries individual accountability), because treating every error as blameworthy discourages the honest reporting that safety engineering depends on to find gaps before they cause harm.
