Costly Signals in Space: Increasing Credibility via Strategic Disclosure
No full textAs space becomes an increasingly vital domain for national security, debates persist about how much secrecy should surround U.S. military space programs. This article argues that the strategic declassification and disclosure of selected space capabilities can strengthen U.S. deterrence by enhancing the credibility of deterrent threats. Drawing from theories of costly signaling and audience costs, the paper introduces strategic disclosure as a novel form of costly signal. Such disclosure imposes bureaucratic and operational costs while exposing capabilities to potential adversary countermeasures—thereby demonstrating resolve and seriousness of intent. In tandem, greater public transparency about space programs cultivates informed domestic audiences capable of imposing audience costs on leaders who fail to follow through on public commitments. Together, these mechanisms can increase the credibility of space deterrence in both general and crisis contexts. By adapting international relations theory to the unique characteristics of the space domain, this study contributes to ongoing discussions about deterrence, transparency, and strategic stability in outer space
Rapid Evidence Review: Terror Incidents and Perceived Terrorism Risks at Events
No full textSince the 1972 Munich Olympics, mass gatherings for sport, music, and other entertainment have been viewed as highly vulnerable, culturally significant targets for terrorist attacks. Although research on the enactment and implications of terrorism have become more commonplace, comparatively little research has examined terrorism in the context of organized gatherings and the event venues which host them. Through a rapid evidence review, we summarize empirical research on (a) international incidents of terrorism and (b) perceived terrorism risks at large-scale public events and event venues, as well as (c) their psychological, behavioral, and social/news media effects. This research brief is intended to inform event organizers, event security professionals, venue owners and operators, and policymakers about terrorism-related risks to public events and event venues
Leveraging Generative AI to Improve Comprehensibility in Social Recommender Systems
No full textGenerative AI, particularly Large Language Models (LLMs), has revolutionized human-computer interaction by enabling the generation of nuanced, human-like text. This presents new opportunities, especially in enhancing explainability for AI systems like recommender systems, a crucial factor for fostering user trust and engagement. LLM-powered AI-Chatbots can be leveraged to provide personalized explanations for recommendations. Although users often find these chatbot explanations helpful, they may not fully comprehend the content. Our research focuses on assessing how well users comprehend these explanations and identifying gaps in understanding. We also explore the key behavioral differences between users who effectively understand AI-generated explanations and those who do not. We designed a three-phase user study with 17 participants to explore these dynamics. The findings indicate that the clarity and usefulness of the explanations are contingent on the user asking relevant follow-up questions and having a motivation to learn. Comprehension also varies significantly based on users’ educational backgrounds
Tolerance of homonegativity and transnegativity predicts negative evaluations of LGBT people and LGBT-supportive policies among US-based heterosexual, cisgender participants
No full textMany people in the United States express anti-LGBT attitudes and oppose LGBT rights. These views are perpetuated when others, including allies, tolerate expressions of anti-LGBT bias. In this study, we adapted and validated a measure of tolerance of homonegativity and transnegativity (TOHT), and assessed its associations with evaluations of LGBT people, straight people, support for LGBT rights, and system-justifying ideologies among heterosexual, straight, binary-gendered/non-trans (i.e., cisgender) women and men who identified as liberal, moderate, or conservative (N = 295). Participants completed measures of TOHT, evaluations of LGBT people, support for LGBT rights, authoritarianism, religiosity, and contact with LGBT people. Analyses by gender and political ideology indicated that all groups tolerated anti-LGBT bias to some degree. Among conservatives, women (vs. men) endorsed TOHT more and exhibited less support for LGBT rights; the opposite was true of liberals. As expected, higher TOHT scores were associated with cooler evaluations of LGBT people and less support for LGBT rights. However, after controlling for system justifying motives, that was only significant for conservatives and moderates potentially suggesting that conservatives and liberals may endorse TOHT for different reasons. Overall, findings suggest that groups traditionally regarded as allies (e.g., women, liberals) tolerate attitudes that disadvantage LGBT people

Same but Different: The Survivability of Arctic-based Russian Second-strike Capability
No full textThis article analyzes the survivability of Russia’s second-strike capability in the Arctic through the lens of classical nuclear deterrence theory. Despite heavy commitments in Ukraine, Moscow continues to modernize its Northern Fleet and reinforce bastion defenses, underscoring the Arctic’s role as the cornerstone of its retaliatory deterrent. While these strategies mirror Cold War practices, they face unprecedented challenges from NATO expansion, multipolar competition, and advances in anti-submarine detection technologies. The study concludes that safeguarding Russia’s second-strike capability not only shapes regional security dynamics but also has broader implications for global strategic stability.
