A useful mindset to search for disconfirming evidence is to make it a game.

In every conversation, challenge yourself to find the hidden great insight lurking within your conversation partner's mind.

No conversation is too fleeting or banal to not have a great insight lurking if you look hard enough.

Approach each conversation as if the person might be enlightened, knowing there's wisdom to be found if you're truly open to discovering it.

Similar to Fred Kofman's advice in Conscious Business to treat everyone you meet as if they were the Buddha in disguise.
