Prone to bias: Development of a bias taxonomy from an individual differences perspective.

We adopt an individual-differences perspective and introduce a model that links types of biases and types of people. We propose that biases are created in the course of people’s attempts to satisfy basic motivations, and that 3 such motivation categories underlie many of the biases discussed in the literature. Accordingly, our organizing framework integrates findings from previous research and classifies biases into verification biases, simplification biases, and regulation biases. Individual differences in core self-evaluations, in approach/avoidance temperament, and in cognitive ability and style help explain how biases come about and why some people are more likely than others to exhibit particular biases.

Dispositional resistance to change: Measurement equivalence and the link to personal values across 17 nations.

The concept of dispositional resistance to change has been introduced in a series of exploratory and confirmatory analyses through which the validity of the Resistance to Change (RTC) Scale has been established (S. Oreg, 2003). However, the vast majority of participants with whom the scale was validated were from the United States. The purpose of the present work was to examine the meaningfulness of the construct and the validity of the scale across nations. Measurement equivalence analyses of data from 17 countries, representing 13 languages and 4 continents, confirmed the cross-national validity of the scale. Equivalent patterns of relationships between personal values and RTC across samples extend the nomological net of the construct and provide further evidence that dispositional resistance to change holds equivalent meanings across nations.

Exploring motivations for contributing to open source initiatives: The roles of contribution context and personal values

We explore contextual and dispositional correlates of the motivation to contribute to open source initiatives. We examine how the context of the open source project, and the personal values of contributors, are related to the types of motivations for contributing. A web-based survey was administered to 300 contributors in two prominent open source contexts: software and content. As hypothesized, software contributors placed a greater emphasis on reputation-gaining and self-development motivations, compared with content contributors, who placed a greater emphasis on altruistic motives. Furthermore, the hypothesized relationships were found between contributors’ personal values and their motivations for contributing.
