I don't see that as a problem. Heuristics are for when you need to make quick decisions. Heuristics are for when you're wondering whether there might be a tiger hiding behind that bush. You're forced to make a snap decision, you can't just rationally evaluate everything, examine the environment and come to the right conclusion. And if you're not paranoid enough some day a tiger might get you. Even a large amount of error is acceptable when your life might depend on it, and an action must be taken now. When we're on a web forum, sitting in a comfortable chair, drinking coffee and not in any kind of hurry to decide one way or another whether something is a good idea, heuristics are harmful and prevent us from reaching correct conclusions.
