Graphs confuse?

I wonder if stock charting inherently misleads (or at least confuses) the reader because we reflexively treat lines as representing physical motion (and thus see momentum (and its corollary, inertia) where there is none). It might be more useful to identify useful graphical representations of similar motion (using physical metaphors is probably a bad place to start but helps to highlight the problem) to avoid seeing patterns (another reflexive trait) where there are none.

awesome awesome

Just an awesome awesome article about health care. Unfortunately, unlikely to have any results but just so correct (and, I can't resist saying, consistent with much of what I've believed and said over the past years).
