Subliminal messaging vs Signs that are everywhere

The book I'm reading now is Vital Lies, Simple Truth by Daniel Goleman.

In it is speaks about how all information that we receive through our senses are actually stored somewhere, but only what is relevant to us, comes into the conscious state - or awareness.

"He would flash words for just a few thousandths of a second - so quickly that people did not even know they had seen a word. Then he would ask his subjects which word in a subsequent pair meant or looked the same as the one that had just flashed by. If for example, the unseen word was 'book,' the lookalike would be 'look' the related word 'read.'

Even though his subjects had not the slightest idea what the first word had been, they were right in their guessing about 90 percet of the time - an astounding rate of accuracy for people who did not even know they were reading." (Chapter : How much we can keep in mind - page 68)

This immediately reminded me of subliminal messaging. Used once, perhaps the effect is minimal, but constant exposure to the same subliminal message? What effect can that have, I wonder.

And then I though about how, perhaps we can put it to good use, perhaps in reminding people such things as 'God sees all that you do' or just'Allah'.

But then immediately I'm thinking.. of course, Allah knows better and Allah knows all. I'm thinking of 'sublime messages' in perhaps my videos, but Allah has made his Signs available everywhere. Look at the birds, the trees, look at the workings of ourselves! These are all Signs to remind us of God's existence and power. It will be of benefit for those who reflect, but will be ignored or dismissed by the arrogant.
