Recently Google released a training material to its employees as part of how unconscious bias can happen in work place. For more details see -

http://www.businessinsider.com/google-unconscious-bias-training-presentation-2015-12 which refers to research paper at http://rd.springer.com/chapter/10.1007%2F978-3-642-82598-9_3

It is very interesting and one of the slide (see below) specifically caught my attention with respect how huge amount of data is NOT processed consciously. That is we can only handle 40 bits for every 11 million bits in a second!

That is just 1 part for every 275,000 parts!!

As interesting as it is the impact I thought will be even more dramatic when visualized it in some way. Following are of couple of attempts at it using

Each tiny square (green or red) in the following picture represents 40 bits and each row has 275 of those squares. With 1000 rows (10 blocks of 100 rows each) of those we get 11 Million bits of data represented. This is just for one second of duration!

Just imagine the the scale for one's life time (80 years) data. All those 275,000 blocks above are to be repeated 2,522,880,000 times!!!

Another way is tiny string, say 5 pixels long, represents 40 bits then total length of 11M bits will be 275k * 5 pixels long! See below. Small green line at the center of the diagram is a string of few pixels and around which the really long string i.e., 275K times long string is wound around a square peg. At each of 25 rounds the string changes color for better visibility. Totally there are 742 sides.

at end of 25th round the length is 5,050 times longer and

at end of 50th round it is 20,100 times

at end of 100th round it is 80,200 times

at end of 150th round it is 180,300 times

and finally at 185.25 round it is 274,111 times longer

Note: Keep in mind it is not the size (area) of the squares but the total perimeter length of all these squares that represents ratio of data.
