考一考：以下结论是可以被证伪的吗？
糖是甜的，盐是咸的。
正确答案是：它们都是可以被证伪的。
如果你的结论与答案相反，那么你并未理解何为“可证伪性”，不足以谈Popper.
“可证伪性”跟“已被证伪”毫不相干。
=====================
What is an example of falsifiability?
For a proposition to be falsifiable, it must - at least in principle - be possible to make an observation that would show the proposition to be false, even if that observation has not actually been made. For example, the proposition "All crows are black" would be falsified by observing one white crow.
