It might come as a surprise to learn that the brain responds to training in much the same way as our muscles, even though most of us never think about it that way. Clear thinking, focus, creativity and good judgment are built through challenge, when the brain is asked to stretch beyond routine rather than run on autopilot. That slight mental discomfort is often the sign that the brain is actually being trained, a lot like that good workout burn in your muscles.



No.
Most people think intelligence and mental skills in an innate trait, therefore this is no point in ‘exercising’ it.
Interesting, I wonder who is teaching that?
it’s not taught, it’s a cultural belief among most americans. they don’t understand that getting good at something requires practice.
