I read the Wikipedia article about the Observer effect and I was a bit confused by the wording of the introductory section.

Does the method of observation collapse the wave function (or define the eigenstate, or "define" the quantum state (I don't know the proper terminology here, sorry)) regardless of whether or not consciousness is involved in the observation?

My understanding from the Wikipedia article's introduction was that the uncertainty of the quantum state is interfered with by both conscious and unconscious observation.

Is this true?
