One of the elements is self training and technical knowlegde. You encourage
that by using increased privileges (spectrum and power) to get people to study
and take
additional tests.

If it were working, it would be evident on the air. But I'll encourage you to
try a little practical experiment to see if you can detect the results in the
real world.

You'll need the following materials for the experiment:

1. A reasonable sensitive receiver, hooked to a working antenna.
2. A blindfold.
3. A set of earphones.
4. No extreme hearing impairments.
5. A comfortable chair.

Seat your self at the receiver, and tune it to the TOP of a popular band with
good propagation to the USA, probably 40 or 75 meters. Don the earphones and
plug them in. Set the receiver RF gain full open and the AF gain at a
comfortable level.

Now place your blindfold over your eyes.

Slowly tune the receiver down the band. If incentive licensing is working, when
you cross over the General/Advanced boundary and again when you cross the
Advanced/Extra boundary, you should detect a noticeable increase in the
"training and technical knowlege" of the operators because of better/cleaner
signals, more sophisticated technical discussions, and other evidence of better
training and technical knowlege. If your ear does NOT detect this sort of
evidence as you tune across those boundaries, then you can conclude (as I have)
that incentive licensing is an abject failure.
