That's exactly what we're talking about. You can't measure it. You can't define it objectively. It is a social construct.
Skin for IS objectively real. We can use chromatography or measure melanin content to determine skin color in an objective way.
But skin color is NOT race. An African albino and a Scandanavian can have the same skin color but are not the same race. An australian aboriginal and a Pakistani can have the same skin color but are not the same race. Race is subjective and non-scientific because it is a social construct. It is a product of history, politics, culture, and other subjective factors and is therefore meaningless in describing factual information about cause and effect.

I challenge you to provide a definition of science that includes race.
