>>911>If there is selection bias, then the categories aren't arbitrary.
That's not how selection bias work.
>Yes it is, because common sense is based generally on very strong reasoning
No it is not. Common sense is based on intuition, peer imitation and superficial observations. Common sense only have to not hinder one's survival in their daily life to perpetuate. It doesn't have to be true. Common sense tells you objects are attracted to the ground, whereas actually there is no attraction but bending of space and time.
Reasoning imply scrutiny, testings, rigorous method. Not being content with premade conclusions.
>the principles which govern scientific study are themselves derived from common sense about how the world works
Absolutely not, the scientific method is a critical one, you put what you think you already know under scrutiny you don't tell yourself "that's just how things are bro" That's the opposite of common sense thinking.
>In order for common sense in this case to be invalid the concept of genetic heritability would have to be false (i.e. it would need to be such that the offspring's genes DON'T correlate with its parents)
1. If you wanna talk about scientific matters, then watch your vocabulary, because genetic heritability doesn't means when parents pass down their genes in the context of biological studies.
2.No, parents transmitting their genes to their offspring do not mean human races are a valid concept. STRUCTURE programs can identify different statistical distribution of alleles, even in neigbhoring continental populations Will you make a special snowflake race for each subpopluation distinguished by that method? Or will you refer to people of Western ancestry as White people? If you choose the former, congratulation you're on par with the 00's-10's Tumblrinas arguing endlessly about their pronouns while anybody not terminally online stick to he/she. If you choose the latter, you cannot use interchangeably race and local markers, there need to be a threshold of differentiation that is big enough to truly distinguish between the races you want to objectivize. Something that would allow a classification with a finite amount of races.
