How to Become an Agnostic. No matter your present religious and spiritual views and affiliations, becoming an agnostic involves some contemplation. There is not a form to fill out or certain group you need to join, but you'll have to reflect on the implications your decision to become an agnostic will have.
Consider your thoughts on God's existence. If you believe there is no higher power, you might consider defining yourself as an atheist. An agnostic is someone who is unsure about a higher power in some way. You can still believe in some form of a god and be an agnostic.
Decide the type of agnostic you want to be. An agnostic theist believes some form of a god exists, however also believes that the true nature of such a being is unknown to humans or is not knowable. An agnostic atheist believes there may not be a higher power or does not see enough evidence of a higher power to decide one exists.
Ask friends and relatives about their thoughts on agnostics. Although you have to decide for yourself whether or not you want to become an agnostic, you'll want to be prepared for their reaction to your decision. Do research and be prepared to answer their questions.
