A recent study from the University of Helsinki has suggested that religious people are more likely to have a poor understanding of the world.
It claims that those with a belief in God are more likely to think that inanimate objects, such as metal and oil can think and feel.
Researchers say that the findings suggest people's lack of understanding about the physical world means they apply their own rules, 'resulting in belief in demons, gods, and other supernatural phenomena'.
Participants were asked how much they agreed with the statement 'there exists an all-powerful, all-knowing, loving God' and if they believed in paranormal phenomena such as ghosts and psychic visions.
They were also tested on a range of other topics, including intuitive physics skills and understanding of basic biology.
The results showed that religious people tend to base their actions on instinct, rather than analytical thinking.
So, which part do you believe in?
