One way of understanding it, which I currently favour, is that by "observing" the result you you yourself also end up in a super position of states, one for each possible "observation". And since by observing it you've "amplified" the result there is suddenly a large difference between those states. These states are then no longer (as heavily) "coherent", and so you will only see the effects from a small region of the states. Most quantum effects will have vanished since those are a consequence of the "coherence" between those states. So from your perspective it looks like the wave function has "collapsed". For instance say you're performing some slit experiment, directly after you launch the particle there is still a very broad spectrum of possible positions / states, which are all heavily correlated since states that differ only by the position of 1 particle are in some sense "close". However if the particle hits something then suddenly there can be a very large number of particles that have different positions, depending on where the initial particle hit, hence the difference between those states increases immensely, causing them to become decoherent. Hence, from the perspective of the resulting states, there is only a very small region where it could have hit, anything else becomes remotely unlikely. This interpretation has some rather interesting issues when you try to interpret what consciousness is, but it's the most consistent one I've found so far.
