Section 9 - The Engineering Mindset was an interesting part of the article.

The proportion of engineers who declare themselves to be on the right of the political spectrum is greater than in any other disciplinary group: 57.6 % of them are either conservative or strongly conservative, as compared to 51.1 % of economists, 42.5 % of doctors and 33.5 % of scientists, 21.4 % of those in the humanities, and 18.6 % of the social scientists, the least right-wing of all disciplinary groups.

The Carnegie survey reveals an even more surprising fact, hitherto unnoticed, that strengthens the suspicion that the engineers’ mindset may play a part in their proneness not only to radicalise to the right of the political spectrum, but do so with a religious slant: engineers turn out to be by far the most religious group of all academics – 66.5 %, followed again by 61.7 % in economics, 49.9 % in sciences, 48.8 % of social scientists, 46.3 % of doctors and 44.1 % of lawyers.

One could question whether this mindset is unique to academic engineers. The answer is likely to be negative: similar results are found on the political and religious opinions of students, both for “un-socialised” beginners in the first four semesters and more advanced ones.

Still, one could further object, the phenomenon could be uniquely American. Some old evidence suggests that at least the right-wing bias occurs in the Middle East: a 1948 survey of 3,890 Cairo University students recorded the highest sympathies for fascist ideology among engineering students (Botman Reference Botman1984, p. 70). A survey of Canadian professors also found that engineers are the least liberal of all (Nakhaie and Brym Reference Nakhaie and Brym1999).

Unfortunately, non-US data that would allow us to combine political and religious attitudes are of much lesser quality.

The results from 2,816 cases in 16 mostly Western countries show that engineers were not more religious than other graduates and only insignificantly to the right of them. However, the combination of the two characteristics occurred far more often among engineers than the null hypothesis of non-correlation would predict – the only professional category in which this happened. Whereas based on individual scores on religiousness and right-wing attitudes we expected 9.4 % of engineers to share both attributes, 13.9 %, actually did (significant at 0.05).
