My view of SR is this: In an absolute sense like "Everything only exists when I believe in it." I don't believe in it. But I think that our beliefs and attitudes play a major part in what we perceive of the world and therefore, they do control part of our subjective reality, that is: the reality we perceive with our brains. But they do so by changing perception, not outer reality.
I think that's what tricks people into believing this. It doesn't make any sense to me, though.
