But a new study published in Psychological Science challenges that assumption by revealing that ethnic minorities, regardless of political affiliation, tend to favor strong leaders more than left-leaning Whites. This preference was linked to levels of generalized trust, with groups expressing lower trust in others more likely to support authoritative leadership.

A new study has revealed a set of proteins in the cerebrospinal fluid that could help identify frontotemporal dementia (FTD) before symptoms appear and track its progression. The findings, published in Nature Aging, come from scientists who analyzed over 4,000 proteins in people with inherited forms of FTD. The research points to disrupted gene expression and damaged brain connections as key features of the disease, offering potential new targets for diagnosis and treatment.

A new study published in Complex Psychiatry has found that people with a history of depression who consume high amounts of caffeine tend to report higher levels of psychological distress. The researchers also found that certain genetic differences are associated with how much caffeine people drink and how sensitive they are to its effects. While caffeine use was not strongly linked to sleep satisfaction, people who said caffeine interfered with their sleep typically consumed less of it.
