Final answer:
The statement is false; trained personnel such as emergency workers or security operators are prepared to make quick and accurate decisions without needing lengthy instructions, as efficient decision-making is a key part of their training.
Step-by-step explanation:
The statement that personnel at an incident will likely need lengthy instructions to accurately perform their duties is generally false. In many high-stakes professions, such as emergency medical services or information security, personnel are highly trained to make quick and accurate decisions. Research in human factors psychology has shown that increased cognitive effort can lead to more mistakes, as was found in the study by Bruno & Abrahão (2012), where operator decision accuracy decreased as the number of decisions increased. Furthermore, in emergency situations, such as those faced by medical personnel or safety workers, decision making and rapid response are critical skills that are honed precisely to avoid the need for lengthy instructions which could delay critical actions.
