A new meta-analysis has shed light on the complex links between hormonal activity and psychopathic tendencies, raising the prospect of more nuanced approaches to identifying and supporting at-risk youth. The study, published in Psychology & Neuroscience, draws on 25 years of worldwide research and upends some previous assumptions about the biology of personality disorders, with potential implications for prevention and mental health services in Thailand and beyond (psypost.org).

At its core, the research reviewed studies examining the role of endocrine system hormones—such as cortisol, testosterone, estradiol, oxytocin, and dehydroepiandrosterone (DHEA)—in the development of psychopathic traits, especially during the sensitive years of adolescence and early adulthood. The strongest and most consistent finding was a statistically significant association between higher baseline levels of cortisol—the body’s primary stress hormone—and the impulsive, antisocial dimension of psychopathy.

A recent study has revealed that many casinos are strategically using blue-heavy lighting schemes to manipulate the behavior and decision-making processes of gamblers, raising fresh questions about the ethics and psychology behind casino design. The research, showcasing the subtle but powerful ways that environmental factors can sway human actions, is particularly relevant to Thailand as it debates the future of legal gaming and examines international best practices amid regional gambling booms.

A new study from the University of Arkansas reveals that stress significantly nudges people toward making riskier choices, with key differences in how men and women respond to decision-making under pressure. The findings, published in the journal Psychoneuroendocrinology, mark an important step in understanding how stress changes our judgment—a topic with direct relevance to the daily lives and financial wellbeing of Thais, especially in uncertain economic times.

At the heart of the research is a concept called “loss aversion,” referring to the well-established human tendency to fear losses more than we value equivalent gains—for example, losing 3,600 baht hurts more than the pleasure of gaining 3,600 baht. Under stress, however, this protective instinct weakens, resulting in bolder, riskier decisions. As the study’s lead author, an assistant professor of psychological science, explains, “In my own life, if I’m stressed, I’ll wait to make a decision that could have potential loss implications.” His reflection echoes a common experience for many Thai workers—such as hesitant investment decisions during periods of high job insecurity or fluctuating market conditions.

It often seems like a no-brainer: after months or even years away from beloved activities or close friends, one might expect people to jump at the first opportunity to return. But surprising new research suggests the opposite may be true—intense longing can actually morph into procrastination, with people intentionally delaying joyous reunions and experiences in the hope of making them even more meaningful. This paradox, revealed in a new study published in the journal PNAS Nexus and summarized by Neuroscience News, uncovers a hidden link between pleasure and procrastination that has powerful implications for personal happiness and social connection (Neuroscience News).

A recent psychological study has found that individuals with higher levels of psychopathic traits are capable of recognizing unfair treatment, but are significantly less likely to act by punishing such behavior. This groundbreaking research, recently highlighted by PsyPost, sheds new light on how personality characteristics influence responses to injustice, raising important questions for educators, mental health professionals, and policymakers in Thailand and worldwide.

Understanding the motives behind moral or antisocial behavior is critical for developing effective interventions in society. For Thai readers familiar with discussions about social justice and community well-being, these findings offer new insights into why some individuals may remain passive witnesses to unfair acts, failing to support victims or deter wrongdoers. While the classic image of the “psychopath” is associated with lack of empathy and disregard for rules, the latest findings suggest that even those with pronounced psychopathic tendencies are not necessarily unaware of what is unfair—they simply make a conscious decision not to intervene.

A decade after its introduction, the EAST framework—representing Easy, Attractive, Social, and Timely—remains a powerful guide for anyone seeking to encourage positive behavior change, from individuals to organizations and governments. First developed by leading behavioral scientists to synthesize a vast body of research on human behavior, EAST has maintained its relevance according to recent reports and continues to shape contemporary strategies for driving change in health, education, and beyond. As the world and Thailand face complex challenges that often hinge on helping people change daily decisions and routines, understanding EAST’s principles is more critical than ever.

In a promising development for anyone struggling to maintain regular physical activity, recent research highlights that combining exercise with another enjoyable activity can significantly enhance motivation to work out. According to a new report covered by Psychology Today, this innovative strategy could hold the key to overcoming common barriers to exercising — an issue especially relevant as Thai society faces rising rates of sedentary lifestyles and related health challenges.

The central finding of the study, as summarized in the Psychology Today article, is that when individuals merge workouts with other pleasurable experiences — such as listening to their favorite music or podcasts while jogging, or exercising with friends — their willingness to participate in physical activity increases markedly. This approach, sometimes referred to as “temptation bundling” in behavioral science literature, leverages the psychological principle of making a less favored task (exercise) more appealing by coupling it with an activity that is intrinsically enjoyable.

A groundswell of new research is challenging the widespread perception that gossip is simply a destructive habit, with evidence emerging that exchanging tidbits about others can actually benefit our mental health and strengthen social bonds. According to psychology experts cited in a recent Fox News report, indulging in gossip—in moderation—could be a surprisingly positive force in our daily lives, while cautioning that, as with many things, too much can turn sour (Fox News). Scientific publications and scholars are re-examining the nature and potential good of gossip, compelling societies like Thailand to re-evaluate how these informal conversations fit into communal life.

In an era of ongoing social, political, and workplace challenges where authority and individual will often collide, understanding why people obey orders is more relevant than ever for Thai society. Recent discussions sparked by “Why We Follow Orders: The Neuroscience of Compliance and Control,” a feature on the Michael Shermer Show, have brought new research to the public eye, shedding light on the brain mechanisms and situational dynamics that drive human compliance. This emerging field offers crucial lessons not only for authorities and educators but also for anyone navigating the fine line between following instructions and maintaining personal agency.

In an era where altruism and humanitarian efforts are celebrated, it might be surprising to discover a type of narcissism that thrives under the guise of good deeds. Recently, the concept of ‘communal narcissism’ has gained attention for its unique characteristics. Unlike the stereotypical narcissist who is overtly arrogant and self-centered, communal narcissists often appear deeply invested in community and charity. However, their underlying motivation is attention rather than genuine concern for others, a trait confirmed by experts in psychology and behavior.
