Most published claims of sex-dependent effects in the neurosciences are missing statistical evidence that the effect differed by sex. We can do better. www.pnas.org/doi/10.1073/... @ossdcomm.bsky.social @sbn-bsky.bsky.social @emoryuniversity.bsky.social @pnas.org @colbyvorland.bsky.social
Only one in four articles presented appropriate evidence for a sex-dependent effect.

Did you know? A 2026 paper argues brains aren’t “born male or female”, they’re shaped by a constant loop between biology and a gendered world. Through neuroplasticity and social expectations, culture wires the brain. Nature + nurture! #ossd #humanhealth #sabv link.springer.com/article/10.1...
