Why do sociologists consider the "scientific" racial types of Caucasian, Mongoloid, and Negroid to be misleading and even harmful?
Step-by-step explanation:
Caucasian, Mongoloid, and Negroid are some of the examples of human races. And they can be explained as
Caucasoid (White) race.
Mongoloid (Oriental/Amerindian) race.
Negroid (Black) race.
They can also be regarded as the three general racial classifications of humans. This means that humans are divisible into broad sub-groups based on phenotypic characteristics such as cranial and skeletal morphology.
Phenotypic characteristics mean those characteristics that are visible or expressed in human.
In this sense, the reasons why the sociologists considered the scientific racial types to be misleading and harmful are those mentioned above.
