1. Personally, I don't think it's ever bad to collect more date and add it to your decision making. (Of course that also means giving due consideration to the nature and quality of the information, not all information is created equally.)
2. I think it's important to change one's mind or modify one's thinking in response to improved information. Just speaking, hypothetically of course, that might lead someone to say. "OMG - I might have underestimated the threat posed by a virus." And action is taken on the basis of the new information. And then as additional information comes in, that person might trim the other direction because the new data sayts that things might not be as bad as the prior data indicated. Or the added information might indicate the need to take extra action. Or the extra information might just make the situation more muddied.
3. One key item is to recognize that all of us, no matter how well trained we think we are or how smart we are, have confirmation biases. The best thing that we can do is to know what our biases are and attempt to counter those biases by being more critical of information and opinions that align with our biases, and less dismissive of information and opinions that we don't agree with. And when we clash, use that as an opportunity to hone our thinking by taking the effort to at least partly remove our bias filters.
