When people say, "I have nothing to hide," they really mean, "I am not ashamed of anything." The truth is, we all have a lot to hide, and shame is just one of many reasons to keep information private or confidential. Having something to hide is not an admission of guilt, and it does not mean you have anything to be ashamed of.

We keep Social Security Numbers private not because we are ashamed of the number, but because we fear identity theft. Sometimes medical conditions remain confidential because others may react irrationally to them.

Privacy is the recognition that individuals and institutions act unreasonably and irresponsibly to the detriment of individuals and society, when in possession of truthful facts. Humans are biased.
