The appeal to pity as a logical fallacy occurs when the writer uses pity and not the merits of a case to persuade the audience. We need more than pity to argue our point. Examples:
We should select Ms. Tosca over Mr. Rodriguez for the promotion because as a single parent she needs the money more than he does.
The financial analysts need our attention because the previous CEO disregarded their input.
