Reddit mentions of I'm Chocolate, You're Vanilla: Raising Healthy Black and Biracial Children in a Race-Conscious World: A Guide for Parents and Teachers

Thanks for making this point. Most of the discussion here centers around adult views of race and racial bias and projecting those onto the choices of the child.

Children display very different object and set comprehension until middle school years. For example, if you take away a preschooler's chair when they're not looking and replace it with a tiny replica, they'll try for quite a while to sit in the tiny replica even though the scale is impossibly small.

Before adults draw conclusions from the doll interview, they should consider this book, for example:

From the Back Cover:

Myth: Black and biracial children dislike their race from the time they are preschoolers.

Reality: Young black and biracial children are unable to understand racial prejudice. In fact, developmentally they are incapable of understanding the concept of race.

A child's concept of race is quite different from that of an adult. Young children perceive skin color as magical—even changeable—and unlike adults, are incapable of understanding the mature concepts surrounding race and racism.
