Asking "What else could be true" opens up the possibility that we might be wrong. It challenges our cognitive biases and invites new perspectives. It helps us seek other people’s views rather than just take the position or 'my way or the highway’.
It challenges that narrow settling on the first thing that comes to mind, which again as human beings we do. Our brains take shortcuts, heuristics. There's been a lot written about heuristics. They're useful until again they're not because those shortcuts can get in the way of us making good decisions and seeing more than otherwise we would.
