Plato distinguishes knowledge (epistēmē) from mere opinion (doxa). Someone can hold a true belief - even end up in the right place - without understanding why. Socrates compares such people to the blind walking the right road: correct, but by luck. Beliefs like that are fragile; without reasons, they can be lost to the first clever argument or the next shift of the crowd. The question makes it personal. Are your values and choices your own, examined and understood, or are you simply following a road someone else put you on? Being right is not enough. Philosophy asks us to see.
