Left-Handedness Linked To Neuroticism? Barely

A widely shared headline says left-handedness is linked to higher neuroticism, drawing on a University of Vienna study published in Brain and Cognition. We look at what the study actually measured — and why a small, single-culture student sample is too thin to carry the claim it inspired. In this episode: - The core finding is real but modest and one-off: right-handed students scored higher on conscientiousness and extraversion, lower on neuroticism. - The sample was small and narrow — 198 students, mostly Austrian or German, from one German-speaking university. - The authors themselves flag that other cultural and demographic groups might differ. - Sex mattered at least as much as handedness in shaping the results. - The depression pattern was tangled, not tidy, with a crossover that resists a simple 'lefties are gloomier' reading. - The proposed brain-lateralization mechanism is a hypothesis, not something the study demonstrated.
