Measuring Relationships between Personality,Knowledge, and Performance using Single‐response Situational Judgment Tests

We report two studies that investigate single‐response situational judgment tests (SJTs) as measures of job knowledge. Study 1 examines relationships between job knowledge measured by a single‐response SJT, personality, and performance for museum tour guides. Study 2 extends Study 1's findings with a sample of volunteers using a single‐response SJT about volunteerism. In both studies, personality was related to knowledge, and knowledge predicted performance. In Study 2, knowledge accounted for incremental variance in performance beyond personality, but personality added no incremental variance beyond knowledge. Results suggest that knowledge of effective behavior and knowledge of ineffective behavior are separate constructs. These studies demonstrate the validity of single‐response SJTs and provide evidence that knowing what to do and what not to do are separate domains.

A Dilemma About Necessity

The problem of the source of necessity is the problem of explaining what makes necessary truths necessarily true. Simon Blackburn has presented a dilemma intended to show that any reductive, realist account of the source of necessity is bound to fail. Although Blackburn's dilemma faces serious problems, reflection on the form of explanations of necessities reveals that a revised dilemma succeeds in defeating any reductive account of the source of necessity. The lesson is that necessity is metaphysically primitive and irreducible.
