Knowledge-based mistakes refer to incorrect decisions made when an individual encounters a new situation and lacks familiarity with the process or lacks adequate training and guidance. These mistakes occur when a person does not have the necessary knowledge to handle a situation correctly. For instance, a new employee might make a knowledge-based mistake when faced with a task they have not been trained to perform. This type of error can be mitigated through proper training and guidance, ensuring that individuals are adequately prepared to handle new situations. It's also important to create an environment where individuals feel comfortable asking for help when they encounter unfamiliar situations.

Choice A is incorrect. Slips are not wrong choices made when someone faces a new situation due to a lack of familiarity with a process. Instead, slips are typically associated with automatic behavior and occur when attention is diverted from the task at hand.

Choice B is incorrect. Rule-based mistakes do not involve an individual deciding to act against the rules. Rather, they occur when an individual makes an error in the application or interpretation of a rule that they understand correctly.

Choice D is incorrect. Violations are not involuntary errors caused by inattention, distraction, and fatigue. They are deliberate deviations from procedures, rules or standards and often result from conscious decisions by individuals who believe their actions will achieve a desired outcome.

Things to Remember

• Human error can be categorized into different types such as slips, mistakes, rule-based mistakes, knowledge-based mistakes, and violations.
