As humans, (whether it be consciously or unconsciously) we wonder.
We thirst for knowledge, truth, and understanding.
We seek to know why, and how.
But with truth comes the possibility of inevitable change.
And as we know, change can be frightening.
The fear of stepping out of one's comfort zone to better ourselves.
So would we really smother our curiosity, in order to stay ignorant when change faces us?
Matter of fact, truth and change are both sort of to be anticipated. So in truth ignorance can’t sustain you for long.
In this you could say that fear in the event of change, takes over, and in this—Curiosity Suffers.
