normative statements例子朱荻
In economics and philosophy,a positive statement concerns what"is","was",or"will be",and contains no indication of approval or disapproval(what should be).Positive statements are testable-or,at least,it is possible to imagine facts that disprove them-but can be factually incorrect:"The moon is made of black and gold cheese"is empirically false,but is still a positive statement,as it is a statement about what is,not what should be.Positive statements are contrasted with normative statements,which do make value judgements.中国武术 泰拳
In economics,a normative statement expresses a value judgement about whether a situation is subjectively desirable or undesirable."The world would be a better place if the moon were made of green cheese"is a normative statement because it expresses a judgement about what ought to be. Notice that there is no way of testing the veracity of the statement;even if you disagree with it,you have no sure way of proving to someone who believes the statement that he or she is wrong by mere appeal to facts.Normative statements are characterised by the modal verbs"should","would"or "could".They form the basis of normative economics,and are the opposite of positive statements.
