Even if you believe that the reports he cites are just another instance of "lies, damned lies and statistics," how do you respond to the information that the folks you work with consider themselves smarter than the average bear? What if they compound their enviable omniscience with a claim to being more infallible than everyone else -- including you? If this is how humans behave time and time again, then you'd be crazy to take at face value internal surveys in which the users of your knowledge management system self-report on their abilities and expectations. After all, it appears that either we don't know ourselves very well or we're not willing to let anyone else know that there may be some foundation to our insecurities. In light of these human tendencies, a knowledge manager would be wise to seek more objective confirmation of the self-reporting. For example, reviewing search queries can tell you a lot about what people are looking for and how good they are at searching. Reviewing help desk requests lets you know when and where users find themselves in trouble. Similarly, usage metrics can tell you whether lawyers actually are trying to use your KM system and which content items seem to be used the most.
But as I write this, I can hear each of you saying to yourselves, "Of course, all of her comments apply to her firm and not mine -- since the smartest lawyers in the world really do work at my firm!"
