>Another item to factor in, beyond lookup table size, is that questions are written in English, and the medium (spelled words) should not be snuck in as part of the content, except where sometimes it is done intentionally :)
That just strengthens my point. The word-length hypothesis doesn't require any information about English. If we change our assumptions to say that the program is being fed the raw visual stimuli (as a human is), then the word-length hypothesis gets even stronger, since it merely involves comparing the widths of the stimuli.
But most of the information about the medium can be ignored when comparing hypotheses because it is constant across them.
