One hypothesis proposed in the article indeed was: "What exactly about engineers’ mindset or cognitive disposition could make them a good match for this ideological cocktail? We can conjecture that engineering as a degree might be relatively more attractive to individuals seeking cognitive ‘‘closure’’ and clear-cut answers as opposed to more open-ended sciences – a disposition which has been empirically linked to conservative political attitudes (Jost et al. 2003; Amodio et al. 2007). Engineering is a subject in which individuals with a dislike for ambiguity might feel comfortable." (But mind you, that is not the author's main hypothesis).
