It is very interesting to find discussion on this. We have actually a group of friends who are all kinda connected with this same issue more or less. We have only recently started to discuss it; framing it "lazy smart" people. Part of our group never got back on track in life despite "high iq". The reality kinda came after people got to good universities and realised that you have to work to progress. Finding motivation to gradute seems impossible when you are used to get everything without effort.
