Interesting article here. It caught my eye because of the parallels with many of the people active in the Christian "Young Earth Creationist" movement in the US and elsewhere. The YEC's aren't notorious for terrorism, although I have no doubt a lot of them would be into it if they thought God was telling them to do it, but what is striking is the number of engineers that are involved in YEC. This has been noted and commented on many times. What is it with engineers and YEC?
Now it looks as is there is a similar and striking correlation between engineers and Islamic extremism. This does not mean that all engineers are either YEC's or Islamic terrorists, but it does seem that people inclined to that sort of thing also tend to be attracted to engineering. I have an idea that it is something to do with seeing everything as designed and as part of a plan, but of course I can't back that with anything solid at this stage. Anyway the article is worth a look. Excerpts below.

Can university subjects reveal terrorists in the making? WHO becomes a terrorist? An MI5 report leaked to London newspaper The Guardian in August 2008 concluded that there is no easy way to identify those who become involved in terrorism in the UK because there is "no single pathway to violent extremism" and that "it is not possible to draw up a typical profile of the 'British terrorist' as most are 'demographically unremarkable'".
Does it follow, as some scholars now think, that anyone, given the right conditions and the wrong friendships, can end up joining a terrorist group? Not entirely. We found that engineers are three to four times as likely as other graduates to be present among the members of violent Islamic groups in the Muslim world since the 1970s. Using a sample of 404 Islamic militants worldwide (with a median birth date in 1966), we tracked down the education of 284. Of these, 26 had less than secondary education, 62 completed secondary education (including madrasas), and 196 had higher education, whether completed or not. Even if none of the cases where we lack data had higher education, the share of those with higher education would be a hefty 48.5 per cent.
The next move was to find out what they had studied - and we tracked down 178 of our 196 cases. The largest single group were engineers, with 78 out of 178, followed by 34 taking Islamic studies, 14 studying medicine, 12 economics and business studies, and 7 natural sciences. The over-representation of engineers applies to all 13 militant groups in the sample and to all 17 nationalities, with the exception of Saudi Arabia.
Our finding holds up quite well in another sample of 259 Islamic extremists who are citizens or residents of 14 western, mostly European, countries, and who have recently come to the attention of the authorities for carrying out or plotting a terrorist attack in the west. Although this sample contains far fewer people with higher education than the older members of the first group, nearly 6 out of 10 of those with higher education are engineers.
We also collected data on non-Muslim extremists. We found that engineers are almost completely absent from violent left-wing groups, while they are present among violent right-wing groups in different countries. Out of seven right-wing leaders in the US whose degrees we were able to establish, four were engineers: for example, Richard Butler, the founder of the neo-Nazi group Aryan Nations, was an aeronautical engineer, and Wilhelm Schmitt, leader of the right-wing, extreme anti-government, pro-localism group known as the Sheriff's Posse Comitatus, was an engineer with Lockheed Martin. Among the total membership of the Islamic groups, however, the over-representation is still much higher.
Why engineers? Everybody's first reaction is that they are recruited for their technical proficiency in bomb-making and communications technology, but there is no evidence for this. A tiny elite tends to do the technical work in these groups, and jihadist recruitment manuals focus on a personality profile rather than technical skills.
So we are left with two hypotheses: either certain social conditions impinge more on engineers than on other graduates, or engineers are more likely to have certain personality traits that make radical Islamism more attractive to them. Our best guess is that the phenomenon derives from a combination of these two factors.
We reckon that something else is going on, something at the individual level, that is, relating to cognitive traits. According to polling data, engineering professors in the US are seven times as likely to be right-wing and religious as other academics, and similar biases apply to students. In 16 other countries we investigated, engineers seem to be no more right-wing or religious than the rest of the population, but the number of engineers combining both traits is unusually high. A lot of piecemeal evidence suggests that characteristics such as greater intolerance of ambiguity, a belief that society can be made to work like clockwork, and dislike of democratic politics which involves compromise, are more common among engineers.
So the bottom line is that while the probability of a Muslim engineer becoming a violent Islamist is minuscule, it is still be between three and four times that for other graduates.
