The phrase “It’s not rocket science” is often used to explain duties that are not tough or sophisticated. But are rocket scientists actually smarter than everybody else?
That was a significant query that researchers sought to reply in a brand new examine revealed within the annual light-hearted Christmas situation of the high-profile medical journal BMJ; the examine additionally utilized the evaluation to mind surgeons. The examine was led by researchers at universities and hospitals in London and Bristol, in addition to U.Ok. charity Brainbook, which is devoted to science communication and engagement with neuroscience.
Researchers gave a take a look at known as the Great British Intelligence Test to each aerospace engineers and neurosurgeons. The take a look at evaluates areas of cognition like planning and reasoning, working reminiscence, consideration, and emotional processing.

The researchers in contrast the outcomes of 300 aerospace engineers to these of 72 neurosurgeons from throughout the United Kingdom, Europe, the United States, and Canada, in addition to to the scores of 18,257 members of the British public who took the identical take a look at. Over 250,000 British folks have taken the take a look at as a part of the BBC Two “Horizon” program’s GBIT project.
The neurosurgeons scored greater than the aerospace engineers in semantic, or word-based, drawback fixing, whereas the aerospace engineers scored greater in psychological manipulation and a spotlight than the neurosurgeons. There have been no different notable variations between their scores.
But how did the sayings maintain up? Compared to the overall inhabitants, neurosurgeons had quicker problem-solving speeds however slower reminiscence recall. There have been no notable variations between the scores of aerospace engineers and the overall inhabitants.
“In situations that do not require rapid problem solving, it might be more correct to use, ‘It’s not brain surgery,’ but in situations where rapid information recall is needed this phrase should be avoided,” the authors wrote within the examine.
The researchers aren’t positive what might be behind the variations they detected. It’s doable, they wrote, that neurosurgeons would carry out higher on word-based duties than aerospace engineers due to their medical coaching, which includes studying the Latin and Greek roots of medical phrases. Aerospace engineers undergo coaching which teaches expertise like consideration and manipulating objects of their minds, which may clarify why they’d carry out higher on these duties.
The variations between the 2 teams and the overall inhabitants are additionally arduous to interpret, in response to the researchers. The authors wrote that although neurosurgery does contain speedy problem-solving, earlier analysis exhibits that fixing issues shortly just isn’t a straightforward talent to show. It’s extra possible, they write, that individuals who have already got fast problem-solving expertise are usually interested in the sphere. It’s unclear why neurosurgeons might need slower reminiscence recall.
The examine has a number of limitations, together with its restricted geographic attain and pattern measurement. But although the examine was lighthearted, concepts about what sort of folks can go into fields like neurosurgery and aerospace engineering have actual penalties. Women, folks with decrease socioeconomic standing, and people who find themselves not white is perhaps much less possible to enter science due to these sorts of associations. Previous research exhibits that college students are likely to view science, know-how, engineering and math (STEM) as “masculine” and “clever.”
Regardless, it is clear that generally, rocket scientists and mind surgeons aren’t actually any smarter than the remainder of us and won’t should be placed on a pedestal. The query is, who does?
“Other specialties might deserve to be on that pedestal, and future work should aim to determine the most deserving profession,” write the authors.
The analysis is described in a paper revealed Dec. 13 in The BMJ.
