Thus, I have great difficulty accepting the contention that it is somehow bad human engineering to use root -> leaf form when specifying a point within a hierarchical address space; it appears that a human mechanism exists which allows a very efficient scan of the higher-level information. In left-to-right languages such as English, there is a significant probability that failing to use this form will result in the scan halting once the local information has been processed, without continuing on to verify the higher-level information. Making the assumption that the higher-level information does not need to be scanned, the lower-level information is put to immediate use. This results in "human error"; the form which requires that the higher-level information be scanned, even automatically, is less likely to result in this "unverified assumptions" error. We now question the defenders of non-hierarchical presentation as to how a form which tends to promote human error represents an advance in human engineering. Bill Wolfe
