This article argues that the human brain saves energy by predicting or imagining “reality” more than actually perceiving it: Do Thrifty Brains Make Better Minds? The article argues that this way of using our brains allows us to work more efficiently with complex data or in complex situations.
I think this general premise is pretty well known and agreed on, but the linked article puts it in a new way. The following sentence caught my eye: This… underlines the surprising extent to which the structure of our expectations (both conscious and non-conscious) may quite literally be determining much of what we see, hear and feel.
The article uses visual perception as an example, but the idea applies just as well, and maybe more so, to what we hear in the speech of others. FIML practice works by inserting a new mental skill between the first arising of a (stored) interpretation and its full-blown acceptance as “reality”.
