Depends what you mean by smarter. You are putting into practice certain skills. When you reach a certain level, then the benefit is minimal.
There is one benefit (if you want to call it that), which is where you dont know the answer, then you go and find it which expands your knowledge. It is questionable whether you really need or benefit that much from the knowledge.
What you can do and sometimes works is getting people to think things through and learn.
