All I have is unwritten anecdotal data that convinces me of the  
*existence* of the phenomenon to a non-trivial extent (from observing  
tool output, from observing what others say when they discuss things  
and from observing that my own thoughts when writing tools or markup  
parallel what I observe others to say or do). It also seems to me that  
the phenomenon of people writing good alt text because a validator  
reminded them *exists*.

My point was that quantitative data about the magnitude of different  
phenomena around alt and how they average out is something we don't
