An experiment:
Go to
Now input “American couple”
Do you see any kind of anamoly?
“American” seems to be linked to “African-American” in the searches.
You can try substituting “U.S.” for “American” and you will get more representative results.
Try this with “inventors”, “scientists”, and “mathematicians.” Even if you put in “U.S” you get a disproportionate number of black people.
But Google is trying so hard, bless their hearts.
Try this: “white american couple” it’s even more fascinating...
