The running gag behind agnosticism is that agnostics are indecisive and afraid to take a stance on anything. It’s not usually said with sincerity, and compared to other belief biases it is extremely tame. Nonetheless, who doesn’t benefit from a bit of clarity?
I identified as an agnostic for nearly ten years, and in that time I met many others who also identified as such. From my experiences and conversations with others I maintain that agnosticism is not about not knowing; it is simply not caring.
