Making a split second decision is a fantastic idea. The human mind has the unconscious ability to sift through piles of information faster than it takes to develop a plan of action. The problem with this concept is the assumption that knowledge and experience are present in that mind of yours. Learning is a big part of successful blinking. If you spend your time batting your eyes at decisions and rationalize that your unconscious is taking care of the dirty work, do not be surprised when the ramifications of your blinking kicks you to the curb.
