We studied the transparency of automated tools used during emergency operations in commercial aviation. Transparency (operationalized as increasing levels of explanation associated with an automated tool recommendation) was manipulated to evaluate how transparent interfaces influence pilot trust of an emergency landing planning aid. We conducted a low-fidelity study in which commercial pilots interacted with simulated recommendations from NASA’s Emergency Landing Planner (ELP) that varied in their associated levels of transparency. Results indicated that trust in the ELP was influenced by the level of transparency within the human–machine interface of the ELP. Design recommendations for automated systems are discussed.

Objectives:To investigate existing knowledge in the literature about end-of-life decision making by family caregivers of persons with dementia, focusing on decision aids for caregivers of persons with advanced dementia, and to identify gaps in the literature that can guide future research.Methods:A literature review through systematic searches in PubMed, CINAHL Plus with Full Text, and PsycINFO was conducted in February 2018; publications with full text in English and published in the past 10 years were selected in multiple steps.Results:The final sample included five decision aids with predominantly Caucasian participants; three of them had control groups, and three used audiovisual technology in presenting the intervention materials. No other technology was used in any intervention. Existing interventions lacked tailoring of information to caregivers’ preferences for different types and amounts of information necessary to make decisions consistent with patients’ values.Conclusion:Research is needed in exploring the use of technology in decision aids that could provide tailored information to facilitate caregivers’ decision making. More diverse samples are needed.

This case study analyzes the factors that influence trust and acceptance among users (in this case, test pilots) of the Air Force’s Automatic Ground Collision Avoidance System. Our analyses revealed that test pilots’ trust depended on a number of factors, including the development of a nuisance-free algorithm, designing fly-up evasive maneuvers consistent with a pilot’s preferred behavior, and using training to assess, demonstrate, and verify the system’s reliability. These factors are consistent with the literature on trust in automation and could lead to best practices for automation design, testing, and acceptance.

What factors influence trust in online information?Americans increasingly get information from social media, public distrust in the mainstream media is growing and "fake news" is an important new phenomenon. This paper examines the factors that influence trust in scientific claims posted via social media, including the use of hyperlinks and readers' values. The paper describes a crowdsourcing-based experimental design using Amazon's Mechanical Turk platform. The core of the experiment was a set of 10 scientific findings reported in open-access, peer-reviewed scientific journals, which were in turn linked to in articles in both the mainstream media and "fake news" sites. Data analysis involved exploration of relationships between trust and the presence or absence of hyperlinks, and between trust and human values using nonparametric statistical methods. In terms of the influence of hyperlinks on trust, inclusion of hyperlinks to scientific journals, mainstream media articles, and even hidden URLs led to higher trust than hyperlinks to "fake news" sites or posts without hyperlinks (p < 0.001). Participants who clicked on hyperlinks to scientific articles placed higher trust in the claims than those who did not (p < 0.001). In terms of the influence of values on trust, values had the most impact in cases where individuals saw, but decided not to click on, hyperlinks; this finding seems to indicate that in the absence of firsthand examination of the hyperlinked sites, participants tend to rely more heavily on their values to determine their trust in a scientific claim. These findings indicate that both the presence and absence of hyperlinks and the values of the reader both significantly impact trust judgments.
