Benchmarks are the standards by which we judge things around us. For example, when you meet a new person, you can use “honesty” as a yardstick against which to judge them.
Values are very important criteria. For example, “sincerity” can be a value when you meet a new person. If you don’t think a person is very happy, you don’t need to worry about that. But if you think it’s unfair, you might think twice about doing anything about it.
