Even if a part of this theory is true, then it will scare people for sure because it would show that everything that is going on is at least partly their fault. By existing you change the world, by observing something you change it. If a tree falls in the forest and nothing is there to hear it, does it make a sound? No.

If the world is what we make it then we have failed badly, because this is not a world I would be proud of. Too many people simply do not think for themselves but are happy to let religion, MSM, TV, music, radio, whatever digital communication, to do their thinking for them. They sit back and enjoy their materialistic life, looking to buy that next shiny car or that big screen plasma, only to further their distractions.
