I usually consider it silly (at best) or deceptive (at worst) when patients decline to know their diagnoses. I mean, isn't more information, more clarity, always better? Then last night, as I snarfed down a box of cookies, I realized that at least this one time, I consciously evaded the nutrition facts. I didn't want to know.
Some folks working in philosophy debate whether there's "a right not to know." I mean, say you could know the day of your death. Would you want to know it? I wouldn't. What if you could know definitively whether there was a god. I bet many people would decline, backing up their choice with some poetic bullshit about "faith." Still, if that's what they want... Everybody has his or her own box of cookies.
But how strong is this supposed "right" to remain ignorant? If you're a sexually active person, is there a right not to know your HIV status? And when it comes time to reproduce (for those who choose to), is it okay to avoid learning whether you carry the gene for Huntington's? Is there a right not to know about social ills? About global warming? About genocide in Darfur? Forrest Gump notwithstanding, is life really like a box of cookies?
