Using social norms to determine what is good or bad. It is the idea that normality is the standard of goodness. This is fallacious because social norms are not the same as norms found in nature or norms that are synonymous with the ideal function of a created system. The conclusion, “therefore, it is good” is often unspoken, but clearly implied.
Examples:
- I am only slightly obese. That is perfectly normal here in America.
