OPENING THE BLACK BOX OF "NOT INVENTED HERE": ATTITUDES, DECISION BIASES, AND BEHAVIORAL CONSEQUENCES

The not-invented-here syndrome (NIH) describes a negative attitude toward knowledge (ideas, technologies) derived from an external source. Even though it is one of the most cited constructs in the literature on knowledge transfer, previous research has not provided a clear understanding of the antecedents, underlying attitudes, and behavioral consequences of NIH. The objective of our paper is to open the black box of NIH by providing an in-depth analysis of this frequently mentioned yet rarely understood phenomenon. Building on recent research in psychology and an extensive review of the management literature on NIH, we first develop a framework of different sources classifying knowledge as "external." We then discuss how a perception as "external" may trigger the rejection of this knowledge, even if it is useful for the organization. Differentiating various functions of an attitude, we hereby identify possible trajectories linking NIH with such biased individual behavior and decision making. We apply this understanding to develop an extensive agenda for future research.
