Believing that since nothing can be 100% true everything is completely false paralyzes society. The temperature that's reported by your thermometer may be off by a degree or so but if you take that to mean it can't be trusted at all you have no basis to trust anything. Sources should be critically evaluated constantly, but sources that are usually more off should be treated differently than sources that are usually more on.
