That "obvious example" has major issue when looking at the population as a whole. If you took a random person on the street and asked what profession they had then the chances are about 50% or higher that they are in a worse gender segregation than technical and programming professions.

Consider this: only 12% of the employed people in Sweden work in a profession which has equal or less gender segregation of 60%/40%. The remaining 88%, also called the wast majority work in a place which is considered gender segregated. technical and programming professions have around 70%-30% gender segregation. They rank very average among all profession, with no distinctive attribute in the area of gender segregation.

What does a average gender segregation for a specific profession say about sex differences vs social constructs? Would not looking at those several profession with 99% or higher gender segregation be more telling? For example, what does the highest male gender segregated profession reported here in Sweden, brick layers, with a ration above 99% tell us about sex differences vs social constructs?
