Balance?

You know, I notice there are a lot of forms where at the end (just for statistical purposes, they assure you  - it will have no effect on the selection of the successful candidate, etc.) they ask your race/ethnicity. Q: if it has no effect, why ask? I sometimes try to find the best way to mess things up - if "other" is offered, and has a fill in I put "Canadian"..

The last option, is usually "I would rather not say"

Which in itself, says a boatload.

Who outside of a white male would not be loudly touting their sex (sorry, gender) or racial advantage?
