In theory, agnosticism is compatible with all but the most dogmatic of religious faiths, but in practice most agnostics are perceived as godless. Agnostics believe that while there is insufficient evidence to prove that there is a god, believing that there is not a god also requires a leap of faith (similar to any religious conviction) that lacks sufficient evidence. Simply put, agnosticism merely asserts that we lack the knowledge to determine whether or not God exists - in a sense, it differs from more explicit atheism by being a position based on a lack of knowledge, rather than a lack of belief. True agnostics would actually not fit on a hypothetical scale between theism and atheism as they would say the argument is unanswerable and could result in anything, almost like SchrŲdinger's cat but where the box can never be opened.<quoted text>
agnostic is someone who neither believes nor disbelieves in the existence of a deity or deities, whereas a theist and an atheist believe and disbelieve, respectively.
Most agnostics, however, can additionally be categorised depending on how their beliefs work out in practice, whether they're more atheistic or theistic. Agnostics may live and act as if there is no God and that no religion is correct, but shy away from the title "atheist" because of the expression of certainty implied. On the other hand, someone may consider themselves spiritual but not religious, or perhaps even nominally follow a religion, but identify as an agnostic in order to convey an honest doubt about the reality of it all.
