Industrial-organizational psychology research is useful for small businesses

Zhou et al.'s (2024) central claim is that industrial-organizational (I-O) psychology research is overly focused on large businesses, and as such, tends to produce irrelevant theories and impractical recommendations for small businesses.I disagree and argue instead that the I-O literature has produced numerous insights into workplace behavior that are relevant to organizations of all sizes.More so, many of the recommendations gleaned from the I-O literature can be easily implemented, require few (if any) financial resources, and are accessible to both large and small businesses alike.I provide examples from two fundamental domains of organizational functioning: hiring and managing employees.
