What Drives Conspiracy Theorists? Inside Their Psychology

featured 95061

Summary: A large meta-analytic review explores the psychological profile of people who endorse conspiracy theories, finding that their beliefs are linked to specific motivations and personality characteristics rather than to widespread mental illness. Analyzing data from 170 studies with more than 158,000 participants, researchers found that conspiratorial thinking is most strongly associated with perceiving threats … Read more

Experimental Stroke Therapy Shows Promise for ALS Patients

featured 13640

New research finds vascular damage in mice with ALS contributes to early development of the neurodegenerative disease, while repairing damage delays disease progression. Neuroscientists at the Keck School of Medicine of USC have identified a vascular contribution to early amyotrophic lateral sclerosis (ALS) pathology in mice and shown that repairing that damage can delay motor … Read more
