Is privacy a right?
A really complex question.
Too much privacy becomes a serious danger to social cooperation, as it allows cheats to avoid detection.
Too little privacy and individual liberty is seriously at threat, because authoritarian groups within society (religious, legal, political, whatever) get too much power and influence.
And all of us tend to behave better when we know someone else is watching.
So it becomes a very delicate balance between individual liberty and creative freedom of expression, and a minimum set of rules necessary to maintain social cooperation.
Rights seem to be inventions of social agreement.
We need to have a right to privacy, and it cannot be so strong as to become a cloak for the worst aspects of human behaviour to shelter behind.
And I tend to be more open with information than most people, as the about page of my blog site ( http://www.tedhowardnz.wordpress.com ) demonstrates – with all relevant medical records available for anyone who is interested.
