Dear Marcus and colleagues,
Katherine Hayles (1990, pp. 59f.) compared this discussion about the definition of “information” with asking whether a glass is half empty or half full. Shannon-type information is a measure of the variation or uncertainty, whereas Bateson’s “difference which makes a difference” presumes a system of reference for which the information can make a difference and thus be meaningful. In my opinion, the advantage of measuring uncertainty in bits cannot be underestimated, since the operationalization and the measurement provide avenues to hypothesis testing and thus control of speculation (Theil, 1972). However, the semantic confusion can also be solved by using the words “uncertainty” or “probabilistic entropy” when Shannon-type information is meant. I note that “a difference which makes a difference” cannot so easily be measured. J I agree that it is more precise to speak of “meaningful information” in that case. The meaning has to be specified in the system of reference (e.g., physics and/or biology). Best, Loet References: Hayles, N. K. (1990).

If this issue of "meaning" versus "meaningless" in the use of the term "information" is not resolved (for the group?) it seems hard (to me) to have truly meaningful exchanges . . . without having to put a "meaningful" or "meaningless" qualifier in front of "information" every time it is use.
