On a serious note, I believe that each and every one of us are drawn to some form of higher being.
For the life of me, even putting aside all that I personally believe, if I was to take part in that experiment, I would still feel drawn by some strong connection to some kind of higher power. With what ari said, with only language, the only difference would be what we would call it.
I can't understand how human's can believe all that is around us was created by some accident, that our creation and existence is merely the product of a 1,000,000,000,000th chance of a certain chemical reaction (whatever the odds are).
It is my belief that atheism and certain scientific research and opinions have been merely a part of human nature to justify our existence and disconnect ourselves with the idea that there is something alot bigger and more powerful than 'us' out there.
We are an intelligent and sophisticated species, amongst a world with such diverse forms of life and occurences, yet in the grand scheme of the universe out there, we appear insignificant. Though it is my belief that the universe is an empty space, created to show how small we are in comparison to the force (i.e. God) who created what we know as the earth/life and the universe.
Religion and faith are two different things. Religion is Man's interpretation and take on how a God would have us act. Many atrocities and manipulation of humanity have been committed throughout history under the name of God. Be it Muslims, Hindu's, Catholicism or Christianity etc. People blame God for events in life such as those described above, yet blame God for the actions of men, who were given free choice by God.
I feel a connection to something bigger, something greater than myself. To be honest, that humbles me which only makes me more respectful and compassionate towards humanity.
Many people say things like 'how can you believe in something that you can't see/feel/hear/touch'. It is my belief that these types of people operate out of only one of two sides of human connection, the physical, the other being spiritual/emotional.
If you want my honest opinion, I feel 'God' in everything, every single part of life I feel a connection.
If you want to be corny, think of the connection like what Qui-Gon Jinn says in Star Wars 'The Force is an energy field surrounding all living things, it lives inside of us and around all of us'.
To bring an end to my rambling, I don't believe that the outcome of the study would work. It is my belief that all humanity feels a connection to a higher being, yet it is society, language and our experiences in life which undermine certain people's connection or desire to 'disconnect' for any variety of reasons.
