Some time ago, The Guardian had a web page which compared IQ with salary/wages. It was interactive, so that readers could take an IQ test, and then see where on the accompanying graph they fell, while contributing to the data. The line graph showed a smooth curve from low pay on the left, matching less intellectual achievement, steepening to the right where the geniuses were the captains of industry. Except in one place, where there was a pronounced spike of IQ matching that of the highest paid, but at the level of pay of the top of the teaching salary scale. It was about halfway along the scale.
