There is scientific evidence that directly refutes this hypothesis. The brain continues to develop and mature through one’s mid to even late 20’s, and there is evidence that concomitant learning continues at its highest level through this last brain maturation stage. So college is the perfect age to continue learning, and in fact, the person may be able at this point to bring the height of their brain’s frontal lobe function to focus at the highest level of critical thinking.
