A recent study from the University of Cambridge put this theory to the test by challenging elite rowers to perform a memory task and a physical rowing task, first separately and then at the same time. Performance in both the memory-related and the physical tasks decreased when the students attempted to accomplish them simultaneously, but their rowing suffered far more than their ability to recall words for the memory task. On average, the participants showed a 30% greater drop in their physical strength than in their cognitive abilities, suggesting the brain does in fact take what it needs first when resources become scarce.

Although the selfish brain theory has been proposed as a possible origin for physical issues like obesity, it may also push back against the idea that we are stuck with an innate level of intelligence. If we can count on our brains to demand our body’s limited resources, can we also count on them to continue to improve even once we’re done growing in adulthood?
