Daniel A. Yudkin and colleagues analyzed a rich dataset of real moral conundrums, the “AITA?” board on the social media site Reddit. A look at 369,161 posts and 11 million comments using qualitative, quantitative, and machine-learning methods finds that dilemmas concerning relational obligations were the most common type of dilemma explored on the board. Researchers often use moral dilemmas to probe the contours of human moral intuitions, but such studies typically take place in depersonalized contexts in which the precise relations between actors are unspecified—an intentional design to omit the potentially confounding noise of relational contexts. Yet most real-world moral dilemmas occur in the context of various familial, work, or community relationships. Daniel A. Yudkin and colleagues analyzed a rich dataset of real moral conundrums, the “AITA?” board on the social media site Reddit. Posters to the board describe their own behavior in context, and ask for opinions about whether they are acting like a jerk—although the board’s full name includes a more profane synonym. A look at 369,161 posts and 11 million comments using qualitative, quantitative, and machine-learning methods finds that dilemmas concerning relational obligations were the most common type of dilemma explored on the board—e.g. spouses worried about being disloyal; roommates seeking fair distributions of rent; parents unsure whether they were doing too much or not enough to care for their children; and so on. Over 80% of posts involved an identifiable relationship between actors. Looking at the responses to posted dilemmas, the authors found that violations of trust, such as lying and cheating, were, on average, evaluated more negatively than acts of harm. The third most negatively evaluated dilemma type pertained to judgmentalness—a potential moral wrong often overlooked in academic studies. According to the authors, the lack of relational context in many studies of morality risks confounding responses as the nature of the relationship between actors may be a constitutive feature of moral cognition.

Researchers at Incheon National University explored how domestic public opinion influences foreign policy alignment decisions among U.S. allies during great power competition. Using a survey experiment centered on South Korea’s potential Quad membership, they found that leaders face audience costs when reversing alignment commitments, particularly from pro-U.S. constituents. The study highlights how shifting public preferences can strengthen or weaken alignment credibility in international politics.

This study presents a novel theoretical framework for understanding the neural mechanisms and social factors that contribute to addiction susceptibility, offering valuable insights for developing new treatment and intervention strategies.

A research team led by Prof. ZHU Yingjie from the Shenzhen Institutes of Advanced Technology (SIAT) of the Chinese Academy of Sciences has revealed the neural mechanisms by which social rank influences vulnerability to drug addiction.

Recent reports indicate burnout among IDF reservists, some of whom have served in multiple combat rounds, for extended periods of time. While reserve duty turnout exceeded 100% at the beginning of the war, current reports show a decline to 75%-85%. Several reasons have been suggested for this drop, such as: harm to reservists' employment and livelihood; negative impact on their families and social lives;
