Suppose a classmate claims that the reason he knows nothing about politics is rational ignorance. What does he mean

He meant that he doesn't know anything about politics since he doesn't want to try to grasp it, preferring instead to remain in a state of non-knowledge and, as a result, reasonable ignorance.

When the perceived expense of educating oneself on a topic exceeds the predicted potential advantage that knowledge would give, rational ignorance is the result.
