Welcome back to Science You Can Bring Home To Mom! This month, in honor of pride month, we are discussing the science behind gender and biological sex. Just like many other attributes of the human brain, our common understanding of gender is rife with oversimplification and misunderstanding. But digging a little deeper can help us learn to empathize with others and understand ourselves better. As a human attribute, gender is inherently biopsychosocial—it’s influenced by biological, psychological, and social factors. And each of these paradigms is far more complex than it may seem on the surface. Next week, we’ll dissect some…
