Making do with the I-function

Submitted by meroberts on Mon, 04/26/2010 - 1:23am.

The more we learn about the I-function and its role in shaping our images and perceptions, the more confused I am about its purpose. It limits the sensory input received by the brain and it distorts our perception of reality. Yet, there must be some reason for it since we (presumably) all have an I-function. I understand that it limits the amount of information that the brain has to process and respond to, but I don't understand the underlying process of filtration. Why is it that some input is indeed interpreted by the brain but other sensory information is discarded? Is the same type of input discarded consistently or is it a random process? Moreover, what type of information am I missing because my brain can't, or won't, process the information?
