Two books I've recently read are The Age of American Unreason by Jacoby [1] and Unscientific America by Mooney & Kirschenbaum [2]. Both are worth reading, but Jacoby gives a deeper and more thoughtful analysis and spends considerable time on historical roots and trends.
This topic is tied heavily to politics, and I hesitate to get into that here. I will say this: science is about exploring, like math is about exploring. Viewing science and math as pragmatic skills reduces them to engineering and accounting. Now there's nothing wrong with engineers and accountants and we desperately need and value their skills. But we also need scientists and research mathematicians who explore mysteries for the sake of discovery. There are a lot of subtle implications of that which are completely lost on people who think of science and math as purely functional, vocational pursuits. The benefits of science and math that have been capitalized on by engineers are spin-offs of people with curiosity exploring for exploration's sake. When exploration for its own sake is devalued, the engineers of the world find once fertile ground growing barren.
