A therapist can be honest and wrong at the same time. I prefer that my therapist tells me what she really thinks so that if it's off, we can talk about it; if it's true, then I will sit on it, think about it, and go back to it later when I've had time to digest it. A few times, she's spontaneously said things she regretted, and that have caused hurt or misunderstanding, but I was glad for it because, again, it gave me insight into her perceptions (the same way they do with us) and we could work things out from there. I like those kind of spontaneous utterances and would not want to discourage them.
