Part of the reason why psychedelics are so invaluable to humanity. The amount of information we filter out constantly is vast compared to the minute details we do notice consciously.
I found perception to be greatly enhanced after having glimpsed an "unfiltered" world for a few hours.
It will also blast open the confines of subtext, make people perceptive of the minute energetic shifts in communication and interaction and will drastically enhance the trust in intuition-information to make better conscious decisions.

And while overcaution and even suspicion do not have to be the motivation for paying more attention to our surroundings I get the feeling that our lives would be much less messed up as societies if we each were not fooled so easily by the big league magicians of our age and their age-old tricks.
