During a Gala party scene in Gattaca, a woman submits a saliva sample from a recent kiss to screen her potential boyfriend/husband's DNA. Is she violating rights by doing this without his knowledge? Is this, in any way, similar to performing a background check? How would a DNA screen reveal someone's personality and intelligence?
Of course that is a violation of his privacy. Medical information is supposed to be kept confidential and she was submitting this DNA for testing without his consent. Medical laws are in place to protect an individual's privacy against discrimination and prejudice. For example, if an insurance company saw a person's DNA, they might reject an applicant based on his or her genetic background. Intelligence and personality have an environmental component as well as a genetic component and would be more difficult to predict. However, the show you were viewing was a science fiction show with themes that are rooted in reality. In the future, who knows how far our privacy may be violated?
