We know that gay men have more symmetrical brains than straight men, a structure that more closely resembles women’s brains.
New research demonstrates that higher brain symmetry gives gay men an enhanced ability over straight men to recall faces, a skill women typically excel at.
The same researchers found a corresponding correlation with handedness.
Left-handed heterosexuals were better at facial recognition than left-handed homosexuals and right-handed heterosexuals, which aligns with our knowledge that women and left-handed men have more bilaterally symmetrical brains than right-handed men.
