I'm not even sure that's always the case. There's plenty of cases where you can be right, but not seen to be right for years, and be miserable for all of that time, and still be miserable even when you're seen to be right at the end of it. If everyone you're working with is pursuing a poor plan that may fail, is it better to fight them about how you may be smarter than them over the next few years, or just be along for the ride, hope for the best, and then be courteous about it if it does go wrong and not rub in your foresight?
