Lois Lee in The Conversation:
Many atheists think that their atheism is the product of rational thinking. They use arguments such as “I don’t believe in God, I believe in science” to explain that evidence and logic, rather than supernatural belief and dogma, underpin their thinking. But just because you believe in evidence-based, scientific research – which is subject to strict checks and procedures – doesn’t mean that your mind works in the same way.
When you ask atheists about why they became atheists (as I do for a living), they often point to eureka moments when they came to realise that religion simply doesn’t make sense.
Oddly perhaps, many religious people actually take a similar view of atheism. This comes out when theologians and other theists speculate that it must be rather sad to be an atheist, lacking (as they think atheists do) so much of the philosophical, ethical, mythical and aesthetic fulfilments that religious people have access to – stuck in a cold world of rationality only.
The problem that any rational thinker needs to tackle, though, is that the scienceincreasingly shows that atheists are no more rational than theists. Indeed, atheists are just as susceptible as the next person to “group-think” and other non-rational forms of cognition. For example, religious and nonreligious people alike can end up following charismatic individuals without questioning them.
