Someone asked, “What if I have unjustified true beliefs? sometimes I just pick something to believe without trying to justify it.”
 
To me, something that is unjustified and not legitimately supported at all, is likely not true or should be held in great doubt. One can evaluate justification with reliabilism and then check the truth status by using the correspondence theory of truth.
 
Reliabilism is a general approach to epistemology that emphasizes the truth-conduciveness of a belief-forming process, method, or other epistemologically relevant factor. The reliability theme appears both in theories of knowledge and theories of justification.
 
The correspondence theory of truth states that the truth or falsity of a statement is determined only by how it relates to the world and whether it accurately describes (i.e., corresponds with) that world.
