Is you do an experiment to see we whether X affects Y, and get a p = 0.05, you can say, "Either X affects Y, or it doesn't and an unlikely fluke event occurred during this experiment that had a 1 in 20 chance."
Usually, this kind of thing is publishable, but we've decided we don't want to read the paper if that number gets any higher than 1 in 20. No one wants to read the article on, "We failed to determine whether X has an effect on Y or not."
