I've always felt like stating percentages only provide an illusion of rigor. They're still based on vague intuition. I also think there's nothing wrong with sometimes thinking in absolutes. In some cases it's okay to think that you have enough information to tell that something definitely will or will not happen. Hedging your bets in every single case is a lack of optimization. You need to restrict the search space to save time and energy, like how we use the cut operator in Prolog.
