"These days, agnosticism is often mischaracterized as an undecided response to a question. And in fact, the term is frequently applied outside of a religious context when describing things for which we haven't yet made an opinion.... Alternately, it's used to express our ambivalence about something, using the term to equate to such sentiments as, 'I don't care,' 'I don't really want to know,' or 'I don't even want to think about it.' But this casual usage of the term betrays its original purpose, an epistemological stance and methodology in which skepticism and empiricism — two hallmarks of the scientific method — takes center stage."
