You should seek the truth but never settle on it. You can make assumptions to get you closer to the truth, but I find that asking the right questions can help to engage the person in a discussion, as people are generally self-interested and usually like telling others about their opinion on things. I try not to ask too many loaded questions, because I feel like that's just a question with built in assumptions, but asking questions you already assume they don't have an answer to can sometimes allow people to see things from a different perspective, and that's how change should happen. Less forced narratives, and more questioning the narratives. But nowadays, if you question the narrative, some people like to demonize you and argue that you are against the narrative, when in reality, it's more about trying to figure out if the narrative does more harm than good.
