of insight? I have certain unusual beliefs which i also feel can be tested, but lack the opportunity to test them. They are, however, firmly held although i don't feel particularly preoccupied with them and tend not to mention them to other people because i expect scepticism and stigmatisation. This seems to me to mean that the ideas are not overvalued and that i do have insight about their bizarre nature. Is that evidence that i'm not psychotic? In a more general sense, are there well-defined mental disorders which involve neither lack of insight nor overvalued ideas, and if so, what are they?
