The introductory chapter includes how to design-in good practices in theory, data collection procedures, analysis, and interpretations to avoid these bad practices. Given that bad practices in research are ingrained in the career training of scholars in sub-disciplines of business/management (e.g., through reading articles exhibiting bad practices usually without discussions of the severe weaknesses in these studies and by research courses stressing the use of regression analysis and structural equation modeling), this editorial is likely to have little impact. However, scholars and executives supporting good practices should not lose hope. The relevant literature includes a few brilliant contributions that can serve as beacons for eliminating the current pervasive bad practices and for performing highly competent research.

This issue is a selected bibliography covering the subject of leadership.

Prior research in psychology reports an age-based bias against narcissists. We examine whether managers' reactions to narcissistic subordinates exhibit a similar bias. Using an experimental method, where we manipulate subordinate narcissism, we find evidence of an age-based bias. Older managers react to a narcissistic subordinate by making conservative revisions to the subordinate's aggressive accounting estimates. They do so even at the cost of failing to meet a personally beneficial earnings target. A test of moderated mediation shows the actions of older managers (in their late 40s and older) were driven by their negative perceptions of the narcissistic subordinate. Our work demonstrates that not all individuals perceive narcissists the same way, and has implications for manger/subordinate relationships, and group dynamics involving mixed personalities and ages.

At a meeting of the Stepney Borough Council on June 20th the Public Health Committee submitted the following report by the Medical Officer of Health detailing the proceedings which have been instituted against a certain milk‐vendor during the past eight years, and illustrating the difficulties which are experienced in obtaining convictions for adulteration of milk in consequence of the provisions of the “warranty clause” of the Sale of Food and Drugs Acts.

It has long been recognised that humans draw from a large pool of processing aids to help manage the everyday challenges of life. It is not uncommon to observe individuals adopting simplifying strategies when faced with ever increasing amounts of information to process, and especially for decisions where the chosen outcome will have a very marginal impact on their well-being. The transactions costs associated with processing all new information often exceed the benefits from such a comprehensive review. The accumulating life experiences of individuals are also often brought to bear as reference points to assist in selectively evaluating information placed in front of them. These features of human processing and cognition are not new to the broad literature on judgment and decision-making, where heuristics are offered up as deliberative analytic procedures intentionally designed to simplify choice. What is surprising is the limited recognition of heuristics that individuals use to process the attributes in stated choice experiments. In this paper we present a case for a utility-based framework within which some appealing processing strategies are embedded (without the aid of supplementary self-stated intentions), as well as models conditioned on self-stated intentions represented as single items of process advice, and illustrate the implications on willingness to pay for travel time savings of embedding each heuristic in the choice process. Given the controversy surrounding the reliability of self-stated intentions, we introduce a framework in which mixtures of process advice embedded within a belief function might be used in future empirical studies to condition choice, as a way of increasingly judging the strength of the evidence.
