There was such a standardized test when I was in high school, for what it's worth. And some states still have them, and some require a passing grade on them to graduate from high school.

Popper was specifically referring to levels of intolerance that cause people to move from the world of discussion to the world of physical force. That is, per Popper, tolerating people who will physically harm you as part of the discussion
