An Australian psychologist named Luise Kazda has studied this very question. In a 2021 review paper, she and her colleagues found 14 studies in which receiving an A.D.H.D. diagnosis created a sense of “empowerment” by “supporting a sense of legitimacy accompanied by understanding and sympathy as well as decreased guilt, blame and anger.” But in 22 other studies, Kazda wrote, …

Maybe they actually are, according to Leor Zmigrod, a neuroscientist and political psychologist at Cambridge University. In a new book, “The Ideological Brain: The Radical Science of Flexible Thinking,” Dr. Zmigrod explores the emerging evidence that brain physiology and biology help …

Scientists have long struggled to understand how human language evolved. Words and sentences don’t leave fossils behind for paleontologists to dig up. A genetic study published on Tuesday offers an important new clue. Researchers found that, between 250,000 and 500,000 years ago, a gene known as NOVA1 underwent a profound evolutionary change in our ancestors. When the scientists put the …
