Abstract

Philosophers have long debated whether moral virtue contributes to happiness or whether morality and happiness are in conflict. Yet, little empirical research directly addresses this question. Here, we examined the association between reputation-based measures of everyday moral character (operationalized as a composite of widely accepted moral virtues such as compassion, honesty, and fairness) and self-reported well-being across two cultures. In Study 1, close others reported on U.S. undergraduate students’ moral character (two samples; Ns = 221/286). In Study 2, Chinese employees (N = 711) reported on their coworkers’ moral character and their own well-being. To better sample the moral extremes, in Study 3, U.S. participants nominated “targets” who were among the most moral, least moral, and morally average people they personally knew. Targets (N = 281) self-reported their well-being and nominated informants who provided a second, continuous measure of the targets’ moral character. These studies showed that those who are more moral in the eyes of close others, coworkers, and acquaintances generally experience a greater sense of subjective well-being and meaning in life. These associations were generally robust when controlling for key demographic variables (including religiosity) and informant-reported liking. There were no significant differences in the strength of the associations between moral character and well-being across two major subdimensions of both moral character (kindness and integrity) and well-being (subjective well-being and meaning in life). Together, these studies provide the most comprehensive evidence to date of a positive and general association between everyday moral character and well-being.

Here are some thoughts:

This research concludes that moral people are, in fact, happier. Across three separate studies conducted in both the United States and China, the researchers found a consistent and positive link between a person's moral character—defined by widely accepted virtues like compassion, honesty, and fairness, as judged by those who know them—and their self-reported well-being. This association held true whether the moral evaluations came from close friends, family members, coworkers, or acquaintances, and it applied to both a general sense of happiness and a feeling of meaning in life.

Importantly, the findings were robust even when accounting for factors like how much the person was liked by others, and they contradicted the philosophical notion that morality leads to unhappiness through excessive self-sacrifice or distress. Instead, the data suggest that one of the primary reasons more moral individuals experience greater happiness is that their virtuous behavior fosters stronger, more positive relationships with others. In essence, the study provides strong empirical support for the idea that everyday moral goodness and personal fulfillment go hand-in-hand.

Moral trauma, moral distress, moral injury, and moral injury disorder: definitions and assessments

Abstract

We propose new definitions for moral injury and moral distress, encompassing many prior definitions, but broadening moral injury to more general classes of victims, in addition to perpetrators and witnesses, and broadening moral distress to include settings not involving institutional constraints. We relate these notions of moral distress and moral injury to each other, and locate them on a “moral trauma spectrum” that includes considerations of both persistence and severity. Instances in which moral distress is particularly severe and persistent, and extends beyond cultural and religious norms, might be considered to constitute “moral injury disorder.” We propose a general assessment to evaluate various aspects of this proposed moral trauma spectrum, and one that can be used both within and outside of military contexts, and for perpetrators, witnesses, victims, or more generally.

Here are some thoughts:

This article proposes updated, broader definitions of moral injury and moral distress, expanding moral injury to include victims (not just perpetrators or witnesses) and moral distress to include non-institutional contexts. The authors introduce a unified concept called the “moral trauma spectrum,” which ranges from temporary moral distress to persistent moral injury—and in severe, functionally impairing cases, possibly a “moral injury disorder.” They distinguish moral trauma from PTSD, noting different causes (moral transgressions or worldview disruptions vs. fear-based trauma) and treatment needs. The paper also presents a new assessment tool with definitional and symptom items applicable across military, healthcare, and civilian settings. Finally, it notes the recent inclusion of “Moral Problems” in the DSM-5-TR as a significant step toward clinical recognition.

Scaling Laws Are Unreliable for Downstream Tasks: A Reality Check

Abstract

Downstream scaling laws aim to predict task performance at larger scales from pretraining losses at smaller scales. Whether this prediction should be possible is unclear: some works demonstrate that task performance follows clear linear scaling trends under transformation, whereas others point out fundamental challenges to downstream scaling laws, such as emergence and inverse scaling. In this work, we conduct a meta-analysis of existing data on downstream scaling laws, finding that close fit to linear scaling laws only occurs in a minority of cases: 39% of the time. Furthermore, seemingly benign changes to the experimental setting can completely change the scaling trend. Our analysis underscores the need to understand the conditions under which scaling laws succeed. To fully model the relationship between pretraining loss and downstream task performance, we must embrace the cases in which scaling behavior deviates from linear trends.

Here is a summary:

This paper challenges the reliability of downstream scaling laws—the idea that you can predict how well a large language model will perform on specific tasks (like question answering or reasoning) based on its pretraining loss at smaller scales. While some prior work claims a consistent, often linear relationship between pretraining loss and downstream performance, this study shows that such predictable scaling is actually the exception, not the rule.

Key findings:

• Only 39% of 46 evaluated tasks showed smooth, predictable (linear-like) scaling.
• The rest exhibited irregular behaviors: inverse scaling (performance gets worse as models grow), nonmonotonic trends, high noise, no trend, or sudden “breakthrough” improvements (emergence).
• Validation dataset choice matters: switching the corpus used to compute pretraining perplexity can flip conclusions about which model or pretraining data is better.
• Experimental details matter: even with the same task and data, small changes in setup (e.g., prompt format, number of answer choices) can qualitatively change scaling behavior.

Conclusion: Downstream scaling laws are context-dependent and fragile. Researchers and practitioners should not assume linear scaling holds universally—and must validate scaling behavior in their own specific settings before relying on extrapolations.
