It may not be rocket science, but researchers have found aerospace engineers and neurosurgeons (神经外科医生) are not necessarily brighter than the general population.
Researchers examined data from an international group of 329 aerospace engineers and 72 brain surgeons who completed 12 tasks online using the Great British Intelligence Test.
The tasks examined various aspects of cognition (认知), including planning and reasoning, working memory, attention, and emotion processing abilities. The researchers then compared the results against those previously gathered from more than 18,000 members of the British public.
The findings, which were recently published, reveal that only neurosurgeons showed a significant difference, with quicker problem-solving speed but slower memory recall compared with the general population. "The difference in problem-solving speed exhibited by neurosurgeons might arise from the fast-paced nature of neurosurgery, which attracts those with a pre-existing talent for rapid processing, or it could be, though less likely, a product of training for rapid decision-making in time-critical situations," the researchers noted.
The researchers said the study was, in part, carried out to lay to rest the question of whether one of the professions had the intellectual upper hand-a tension made famous by a comedy show in which a confident neurosurgeon is slapped down by an aerospace expert who says, "Brain surgery... it's not exactly rocket science, is it?"
However, the team found few differences between the cognitive abilities of aerospace engineers and neuroscientists, although the results suggest the former had higher scores for attention and mental control—such as turning objects in one's head—while neurosurgeons showed higher scores in semantic (语义的) problem solving—such as definitions of rare words.
"Essentially what we think it shows is that everyone has a range of skills, some people are better at some things and other people are better at other things, and it is very difficult to be better in everything across the board," said Aswin Chari, an author of the study.
