To be fair, I would say that a "correct algorithm" is one that lives up 
to its specifications.  "Validating input" could be unnecessary and time 
consuming, for instance.  If I design a function to compute a (real) 
square root.  It's not necessarily my job to indicate what happens if 
the function is passed -3; maybe it will reformat the hard drive!  : )   
This is sort of the philosophy of the C programming language--that 
people know what they are doing.  Like you said, I think, being an 
expert in one area doesn't make one an expert in all areas.
