In a recent paper in this journal, Knoll et al. question three studies from our laboratory. In this response to that paper, we address deficiencies in their “reproduction.” Notably, we demonstrate that their data provide little evidence of a negativity bias among research subjects, suggesting a failure not only to reproduce findings from our earlier studies, but also a failure to find a widely acknowledged universal human physiological response trait. This situation raises a number of questions regarding the data on which their analyses are based. We explore these questions below and speculate that Knoll et al.’s data collection procedures may compromise their ability to speak to the external validity of earlier studies.
