Curiosity and exploration
Intrinsic motivation theorists say that the exploratory behavior and intellectual activity are two expressions of interest in the underlying learning.
The exploratory curiosity is the result of attracting new stimuli accompanied by lack of dread or fear, while the intellectual curiosity is embedded within the ideas and the need to think.
Curiosity is defined as a need, desire or thirst for knowledge and that curiosity is essential for motivation
We see people who constantly seek the meaning of things, but fear risking their exploration of the unknown.
The risk factor is important.
