JS Investment is looking for an employee skilled in solving logical problems. What type of test should they administer?

The correct choice is an intelligence test because it directly assesses an individual's ability to solve logical problems, which is a core component of cognitive functioning. Intelligence tests are designed to measure various mental capabilities, including reasoning, problem-solving skills, and the ability to understand complex concepts. This makes them particularly suitable for roles that require analytical thinking and logical reasoning, which appears to be what JS Investment is seeking in their new employee.

Competence tests focus more on specific skills related to a particular job rather than general logical reasoning ability. While they can be helpful in assessing task-specific capabilities, they do not provide insights into an individual's overall intellectual capacity or reasoning skills. Personality tests evaluate traits and behavioral styles, which, while valuable for understanding how a person might fit within a team, do not measure logical problem-solving abilities. Work sampling involves testing a candidate's performance on actual tasks they would face in the job, which may not strictly reflect their logical reasoning skills outside the context of those specific tasks. Thus, an intelligence test is the most appropriate choice for measuring logical problem-solving skills.
