Sociology studies cultures and their norms. Is lying about financial statistics part of some cultural norm?
Yes. I found this on the subject:
Present-day psychologists, sociologists, and other investigators who examine lying as a type of behavior commonly view it as a normal aspect of human existence, whether in personal relationships or in the public sphere. By treating it as an everyday occurrence, an ordinary fact of social life rather than an exceptional event, they have as one of their purposes the collection of data as to how often people lie, what they lie about, to whom they lie and in what situations, and the reasons they give for telling lies.
While they do not, of course, endorse lying, they refrain from moralizing over it, rarely if ever speak of the desirability of a love of truth, and also recognize that lying may often serve a beneficial purpose.
