The Stupidity of the Tariffs Are the Achievement of a Lifetime

You might have seen the various data points suggesting that Americans are losing their ability to reason.

The trend starts with the young. The percentage of fourth graders who score below basic in reading skills on the National Assessment of Educational Progress tests is the highest it has been in 20 years. The percentage of eighth graders below basic was the highest in the exam’s three-decade history. A fourth grader who is below basic cannot grasp the sequence of events in a story. An eighth grader can’t grasp the main idea of an essay or identify the different sides of a debate.

Tests by the Program for the International Assessment of Adult Competencies tell a similar story, only for older folks. Adult numeracy and literacy skills across the globe have been declining since 2017. Tests from the Organization for Economic Cooperation and Development show that test scores in adult literacy have been declining over the past decade.

Andreas Schleicher, the head of education and skills at the O.E.C.D., told The Financial Times, “Thirty percent of Americans read at a level that you would expect from a 10-year-old child.” He continued, “It is actually hard to imagine — that every third person you meet on the street has difficulties reading even simple things.”

This kind of literacy is the backbone of reasoning ability, the source of the background knowledge you need to make good decisions in a complicated world. As the retired general Jim Mattis and Bing West once wrote, “If you haven’t read hundreds of books, you are functionally illiterate, and you will be incompetent, because your personal experiences alone aren’t broad enough to sustain you.”

Nat Malkus of the American Enterprise Institute emphasizes that among children in the fourth and eighth grades, the declines are not the same across the board. Scores for children at the top of the distribution are not falling. It’s the scores of children toward the bottom that are collapsing. The achievement gap between the top and bottom scorers is bigger in America than in any other nation with similar data.
