I met a girl the other day at uni who asked me my view on this question.
A personal conviction is easier to formulate if you have lesser knowledge about a given topic.
Our world is outside absolutes. The actual possibilities are relative to constant variables and factors that influence all aspects of the impossibility.
Therefore, if a fool or fanatic is certain of himself or herself, it only means that they are certain within their limited scope of knowledge.
Their answer was easier to formulate opposed to a wiser person, as they only knew a limited amount of possibility.
So obviously, the more knowledge and wisdom you attain the harder it is to formulate an answer.
The story of Bec:
Bec is an 18-year-old girl who lives with her parents. She has a formal education, up to year 12, and believes she has a solid understanding of religion and philosophy.
I met her the other day at a youth retreat. I asked her what her thoughts were about the meaning of her existence.
She looked at me, smirked and told me that life is a dance floor and that God is the DJ.
I thought this was an interesting response so I asked her another question:
At the end of the night, when the lights have faded, the music has stopped and the DJ has left with everyone else, where will you continue to dance forever and where?
I never got a response. She changed the subject after about three minutes of silence.
