Albert Einstein famously said, "Each child is born a genius". But we do not see many geniuses around us. Hence the obvious question - where do these geniuses go? Many educationists and thinkers have tried to solve this riddle over the last many decades. More often than not, our industrial age education methodology and socio-economic ecosystem are blamed for this gap. But there may be another very important causal factor to consider. Cognitive Neuroscience suggests that it all changes in the first three years. The developmental inputs that a child gets in the first three years of their life from their parents/caregivers or lack thereof set the stage for lifelong intellectual growth. This perspective has become a part of mainstream scientific thinking as a result of two decades of growth in neuroscience research output, thanks to the sensor and scanner technology that enables the sharper study of human brains. So, Einstein was not wrong. Indeed, each child has the potential to become a genius provided the right developmental inputs are given in the first three years.
