The wavefunction (superposition) of a quantum property of an object (or of a quantum object itself) is a mathematical construct of all the possible values that property of that object may be. However, this wavefunction does not exist as a 'real object' itself. The only reason we have the wavefunction is because until a measurement is taken the actual value of a quantum property of an object cannot be known.
The observer does not influence the value observed, neither does the observer "collapse the wavefunction" because there is no wavefunction (except as an abstract, mathematical concept) to collapse. When physicists talk about "the collapse of a wavefunction" they are speaking in mathematical terms.
The various popular 'theories' involving consciousness being involved in wavefunction collapse are based on a flawed understanding of the physics and the terminology it employs.
