Given the rise of automation adoption in a variety of industries, it is essential we understand how individuals perceive these systems. Previous studies have found that a failure of one component in a system leads to decreased trust across a whole system, but few, if any, studies have considered how users define the confines of a system. To address this gap, this study replicated and extended Mehta et al. (2019) by incorporating measures of trust, similarity, and functional relatedness between six human crew members and six automated components. We noted that our functional relatedness and similarity measures were predictors of the magnitude of trust difference between conditions, with a high degree of shared variance. Our lack of a within subjects design means that future studies should further test whether measures approximating perceptions of ‘system’ (e.g., perceived functional relatedness and similarity) predict the size of contagion effects.

The aim of this research is to survey preferences in the astronomy and astrophysics community as they relate to the next decade of NASA. Preferences are key for understanding how decisions are made by individuals that could aid in projecting community preferences and likely outcomes. The study was performed using a survey methodology and evaluated preferences regarding the decadal survey by prioritizing space-based astrophysics missions and research activities. Thematic analysis was implemented to determine themes within participants' open survey responses. Our results show strong community preferences for observational astronomy and science versatility, capability, and scientific return for the upcoming decadal period. Moreover, our findings also show consensus among subgroups in the community. We elaborate on community preferences by presenting results on mission concepts, mission capabilities, and primary science that NASA should strategically invest in.
