I have come up with a theory. Which differentiates people between the curious and inquisitive from the ones who believe that life is all about following the norms in life. These people are termed as born followers. Here is my explanation.

A person who digs his ears or nose and checks for the output from the dig or find may be seen as curious people in life. And this would somehow lead them in life in pursuing their interest of their own and somehow more incline in that manner. They tend to be very cautious careful, wary and alert.

As for the people who just digs for the pleasure and benefit of the doubt, throws them right away before inspecting the packages tend to fall for surprises easily and are often cheated by con-artists.
