4. Pure agnostic. It's the thinking person's position.
Agnostic is derived from the word ignorant.
So no, while agnostic is about thinking, a thinking person must seek the truth and find it.
Everyone seeks the truth, agnostics simply acknowledge that we haven't found it yet.
Admitting lack of knowledge is, indeed, the smartest position to take, but saying only smart people take it is ignorant.
Not smart people, thinking people. A lot of really intelligent people believe in god or are atheists. But their critical thinking is impaired.
And a lot of dumbasses who "think" they're thinking people believe they know it all.
Smart people are critical thinkers. In the case of ideas about existence, they realize there is a spiritual component to mankind. Mind, Body, Spirit. That latter doesn't fit the tangible aspects of the first two, but just like there is a strong relation between mind and body in illnesses, there is a strong relation with spirit to the first two and a person's relationship with existence. This might explain why Atheists only compose about 3% of the population.

The Religiously Unaffiliated
The religiously unaffiliated population includes atheists, agnostics and people who do not identify with any particular religion in surveys. However, many of the religiously unaffiliated do hold religious or spiritual beliefs. For example, various surveys have found that belief in God or a higher power is shared by 7% of unaffiliated Chinese adults, 30% of unaffiliated French adults and 68% of unaffiliated U.S. adults.
