Leading scientists advocate for a modified approach to assessing policy options on biodiversity and ecosystem services. They argue that hypothetical scenarios do not represent real-world policy options, emphasizing the need for authoritative scientific advice on actual policy choices.
A new study in the Journal of Consumer Research found that rejecting alternatives can lead consumers to reverse their preferences. Consumers may focus on less-preferred options when trying to decide what they don't want, making them more likely to notice appealing features of alternative options.
A new study by Temple University psychologists Jason Chein and Laurence Steinberg found that the presence of peers heightens teens' sensitivity to rewards, leading them to take more risks. The researchers used fMRI to measure brain activity in adolescents, young adults, and adults while playing a simulated driving game.
A study published in Annals of Internal Medicine finds that current legal restrictions hinder the effectiveness of advance directives, which allow patients to specify their end-of-life care preferences. The researchers propose reforms to relax these restrictions and promote universal acceptance of oral advance directives.
A study conducted at four US intensive care units found that caregivers who hadn't discussed life support measures with critically ill patients took nearly two weeks longer to make decisions. Patients' loved ones were also more confident as surrogate decision-makers when they perceived high-quality communication with physicians.
A new study in Journal of Consumer Research found that people who feel depleted from exerting self-control tend to pass up the most desirable choices and opt for options with lower-level features. This is known as the 'easy path effect', where individuals prioritize short-term rewards over long-term benefits.

The researchers discovered that when participants were exposed to these stereotypes, women became less likely to take calculated risks and more cautious in their decisions.
A new study of married couples in the US found that those who score well on a simple test of numeracy ability accumulate more wealth by middle age. Couples where both spouses answered three numeracy-related questions correctly averaged $1.7 million in household wealth, compared to $200,000 for those with poor numeracy skills.

The study suggests mental shortcuts, such as heuristics, contribute to the perception of expertise and trustworthiness in labeled e-commerce tools.
A recent study found that more than half of surrogate decision makers prefer to have full authority over the choice of life-support for incapacitated patients. However, a significant portion want to share or cede power to physicians. The extent of control varies based on trust in the physician overseeing care.
A study of smokers and non-smokers found that smokers have a thinner cerebral cortex, specifically in the medial orbito-frontal region. This region is crucial for reward, impulse control, and decision-making. Further research is needed to determine if smoking causes or contributes to this brain structure change.

This is linked to conditions such as ADHD, where high dopamine levels contribute to impulsive behavior.
A North Carolina State University study reveals that older adults fare equally well as young adults in making intuitive decisions, but face challenges with complex decision-making. Older adults with higher education performed better at remembering specific criteria and utilizing them when making decisions.
An analysis article in CMAJ raises questions about Dr. Bernard Prigent's appointment to CIHR Governing Council due to his ties to the pharmaceutical industry, which may have influenced decision-making on topics related to Pfizer Canada.
Researchers found that voters rely heavily on nonverbal cues, such as facial appearance, to make judgments about politicians' competence. Appearance-based competence judgments reliably predict both voting decisions and election outcomes, particularly among less knowledgeable voters who watch a lot of television.
Researchers from the University of Maryland have discovered that crayfish make surprisingly complex decisions by weighing risks against rewards. By studying the animals' neural activity, they hope to gain insights into human decision-making processes.
