Lack of attention could be our biggest problem in perceiving the way we react to the world.

Hello everyone. I was shown this vid earlier and wondered how it might effect us all when we try to grasp our environment around us and not pay attention to minor details. I'm sure some will be familiar with certain scenarios here.

You board the train, find a seat and open the latest bestseller by your favourite author. The couple sitting opposite are having a conversation, and the driver announces that there will be a short delay to your journey, but you are so engrossed in your book that you are unaware of these sounds. In fact, you have become almost completely oblivious to your surroundings, and you fail to notice that the train is approaching your stop. You reach the end of a paragraph and, looking up from your book, see the train pulling out of the station…

Attention span

Its even worse than that.
As well as ignoring and filtering our environment, the brain actively indulges in changing memories to suit its own needs for a more understandable world.
You cant trust your memories. Not of childhood, not of what you did last Christmas, not of that UFO sighting, not for what you had for dinner last night.
And even, as the cutaneous rabbit illusion shows, what happened mere fractions of a second ago.
Your brain RetCons, and there's nothing you can do about it, or even know that it has happened.
