Full Idea
Discussions of blindsight have tended to ignore just how paltry the information is that blindsight subjects glean from their blind fields.
Gist of Idea
Blindsight subjects glean very paltry information

A Reaction
This is a bit unfair, because blindsight has mainly pointed to interesting speculations (e.g. Idea 2953). Nevertheless, if blindsight with very high information content is actually totally impossible, the speculations ought to be curtailed.
