All this illustrates that if we want to stay in business as test gurus then
we'd better forget about meaningful item hierarchies, sample independence,
additive measures, and other such niceties. Rather, using methods whose
results need to be recalibrated for boys, girls, old, and young, ..,
whatever, ... - and adding a few things like "log(exp(something ...))" to
our tech reports - should greatly help with job security. :)
