Article title: TIL 31% of Americans polled in October 1964 “disapproved” of the Civil Rights Act. Another 10% polled as “Don’t know.”

Innumerate comment:

58% approval means either significant numbers of black people disagreed with civil rights (which obviously isn’t the case) or less than 50% of whites supported it.

Reason it’s innumeracy: White people were about 88% of the US population in 1964. So even if an unlikely 100% of the non-whites were in favor of the Civil Rights Act, it still means that at a minimum, 52% of whites were in favor of the Act.
