My personal experience is also in line with this – there are different types of challenges in various disciplines – analytical thinking and problem solving approaches are relevant in mathematical as well as social sciences.
Also, there’s ample research to show that aptitude and genius are often overrated, and even people with superior mental capacities experience high levels of neuronal activities, and that practice and experience contribute more to success than just being smart.
For more information, check out the book Outliers by Gladwell… and also an article in Scientific American titled: “High-Aptitude Minds: The Neurological Roots of Genius”.
