Rasch: An idea whose time has come?
There are 4 elements necessary for an idea "whose time has come" to run rampant: connection, validation, selling and luck. In his recent Kenneth Myer Lecture, Tim Costello reminded us of Malcolm Gladwell's theory of a Tipping Point.
"Connection" means that people propagating the idea must be well connected to opinion formers and the influential.
"Validation" means that the idea must be supported by some people perceived to be experts.
"Selling" means that the idea must have dynamic advocates who can present the idea clearly and persuasively.
"Luck" means that some of those accidental sets of circumstances, that occur all the time, can be turned to assist the promotion of the idea.
Rasch measurement is advancing on all fronts. We have had 50 years of preparation so that, when we seize that "lucky moment", Rasch will become an "overnight sensation"!

Well said, Mike! Things are definitely building toward a critical mass. The one thing left out of the list of factors contributing to an idea tipping over into general acceptance is a perceived need, and beyond that, a sense of urgency. This latter might sometimes be contrived by consumer marketing, but often has a real substantive basis in reality. And with the increasing calls for accountability in government, education, and health care, improved measurement appears to have a healthy future!
