Convicting the innocent
I always use the comparison to a criminal trial when I discuss the logic of hypothesis testing. When we are making decisions with partial information, we can make two types of error: rejecting a claim when it is true, or accepting a claim when it is false. Finding a guilty person innocent is the first, and finding an innocent person guilty is the second. I found an excellent post illustrating the second here.
