Double Standard

There are many situations in which you should judge two things or people by the same standard. If in one of those situations you use different standards for the two, you commit the fallacy of using a double standard.

Example:

I know we will hire any man who gets over a 70 percent on the screening test for hiring Post Office employees, but women should have to get an 80 to be hired because they often have to take care of their children.

This example is a fallacy if it can be presumed that men and women should have to meet the same standard for becoming a Post Office employee.
