Final answer:
The claim that tests should be the only tool for hiring decisions is false as various other factors like interviewer bias and discrimination should be considered. Tests are part of a comprehensive selection process.
Step-by-step explanation:
The statement that tests should be used as the only selection tool in the hiring process due to a strong correlation between test results and job performance is False. While tests such as personality assessments, IQ tests, and skills tests can provide valuable information about a candidate's qualifications and potential job performance, they are not infallible. Factors such as interviewer bias, attractiveness, and subconscious associations can influence hiring decisions, and there are also concerns about discrimination and limited information on productivity. Therefore, tests are typically used in conjunction with other selection methods, such as interviews and work samples, to create a more comprehensive view of a candidate's suitability for a position.
