I've actually found a mantra which is quite useful for this exact purpose. Whenever I'm talking/thinking and I'm about to say/think "I'm right", I automatically replace it with the more elaborate construction "I dare hope that I'm right" and then mentally append a list of reasons why I think that's the case (to be revised according to further information).
Helps me remain critical yet non-judgmental. YMMV, but I dare hope it works
