I thought Schrodinger's cat was almost dead. Or do I have my cats confused?

Here's the paragraph I wanted the theory for and how I got it in there without ever finding a name for that theory:

"There is a physics theory that says that observing something changes whatever is being observed. In order to collect data you have to manipulate it. The filmmakers responsible for 'Capote' turn a discerning eye on how well that theory translates from hard science to journalism."

I love using farfetched analogies. I don't know how this popped into my head-- it's probably in something Capote says in the movie. I'll have to watch it again and see :).
