Neuroscientist reveals the no.1 trait of highly intelligent people and 5 steps to develop it

In a counter-intuitive take on productivity, a London-based neuroscientist has challenged the conventional wisdom of constant work and proposed that solitude and mental rest are not just beneficial, but a key trait shared by highly intelligent individuals. Drawing from his research, Dr Joseph Jebelli told CNBC Make It that allowing the brain to rest and the mind to wander can significantly enhance creativity and brain function.

Dr Jebelli, who holds a PhD in neuroscience from University College London and has a PhD from the University of Washington, highlighted that from a cognitive perspective, solitude provides the essential space for ideas to flourish. "Whether it’s writing, playing the piano, painting, gardening, praying, or meditating, being alone is often what the brain needs to perform these activities well," he said.  During these periods, the brain is busy forging new synaptic connections, strengthening skills, improving information absorption, and nurturing creativity more effectively, he added.

The doctor also pointed to historical and contemporary examples of highly intelligent and successful individuals who prioritised solitude. Bill Gates, for instance, famously engaged in "Think Weeks" twice a year in the early days of Microsoft, retreating to a cabin with only books. This period of uninterrupted reflection and learning, devoid of external distractions, was credited by The Wall Street Journal with leading to the launch of Internet Explorer in 1995.

Similarly, Leonardo da Vinci was known for his contemplative approach, reportedly spending hours observing his work before making a single stroke, Dr Jebelli added.
