“The gains came in clusters. At the top was sociology, with an average gain of just over 0.6 standard deviations. Then came multi- and interdisciplinary studies, foreign languages, physical education, math, and business with gains of 0.50 SDs or more.
The large middle cluster included (in descending order) education, health-related fields, computer and information sciences, history, psychology, law enforcement, English, political science, biological sciences, and liberal and general studies.
Behind them, with gains between 0.30 and 0.49 SDs, came communications (speech, journalism, television, radio etc.), physical sciences, nursing, engineering, and economics. The smallest gain (less than 0.01 standard deviations) was in architecture.
The list seemed counterintuitive to me when I first studied it, just as the Kalamazoo data had. In each case, ostensibly rigorous disciples, including most of the STEM disciplines (the exception was math) had disappointing results. Once again the foreign languages shone, while most other humanistic disciplines cohabited with unfamiliar bedfellows such as computer science and law enforcement. Social scientific fields scattered widely, from sociology at the very top to economics close to the bottom.
When one looks at these data, one thing is immediately clear. The fields that show the greatest gains in critical thinking are not the fields that produce the highest salaries for their graduates. On the contrary, engineers may show only small gains in critical thinking, but they often command salaries of over $100,000. Economists may lag as well, but not at salary time, when, according to “What’s It Worth” their graduates enjoy median salaries of $70,000. At the other end majors in sociology and French, German and other commonly taught foreign languages may show impressive gains, but they have to be content with median salaries of $45,000.“
Also, entertain yourself by reading the comments where people from other disciplines get all defensive and “not true… We’re too smart too!”.
