Why proving age discrimination at employement isnt easy?

As we learned in class, it isnt easy to eliminate or even catch falsified information provided by survey takers or interviewees. "Age" is one of the most pervasive forms of discrimination. One might hink why so as we all age.

Academic surveys and polls conducted measuring large samples via quantitative methods can be easily misleading. In a sense, a survey taker, at home or phone, can lie about preferences due to non attitudes and trying to cover biases. Similarly, in an interview, lack of annonimity and direct contact with the interviewer might induce false answers to avoid answering an a manner that is deemed unsuitable.

One way to go might be analysing exsisting data such law suits filed citing age discrimination, reviewing resumes for evidences of age-proofing or maybe analysing job posting/descriptions to see if any such overt or covert form of discrimination exists.
