The awful thing is that you can never be aware of what you are not aware of.
When you are dead, you do not know you are dead. It's only painful and difficult for others. The same applies when you are stupid.

Along the same lines, people who aren't talented in a given area tend not to be able to recognize the talents or good ideas of others, from co-workers to politicians. This may impede the democratic process, which relies on citizens having the capacity to identify and support the best candidate or policy.
