Final answer:
A false positive error occurred in the selection assessment, indicating an incorrect prediction of the candidate's job success, not related to anchoring bias or confirmation bias.
Step-by-step explanation:
The error that likely occurred in the selection assessment when the candidate with the highest score was hired but was ultimately unsuccessful on the job is a false positive. This means that the assessment incorrectly predicted the candidate's success in the role. The selection process seemed to indicate that the candidate would perform well, yet in reality, the candidate did not meet the job expectations. It does not refer to wrongful hiring, which involves legal implications, or negligent hiring, where the employer fails to conduct a proper background check. The types of biases mentioned, such as anchoring bias and confirmation bias, are unrelated to this specific human resources concept.
