Kids Seem More Likely to Reject Those Whose Eyes Cross

Children with a condition called strabismus, in which their eyes aren't straight or don't line up with each other, may be less likely to be invited to birthday parties than other children, researchers have found.

Swiss researchers digitally altered photographs of six children from six identical twin pairs to create inward and outward types of strabismus. They asked 118 children, aged 3 to 12 years, to look at these altered photos as well as the unaltered pictures of the children with normally aligned eyes and select whom they would invite to their birthday party.
