There are two ways to evaluate:
Subjectively (expert judgement, peer review, opinion polls)
Objectively: counting things
The same is true of motives: you can assess them subjectively or
objectively. If objectively, you have to count things.
Philosophers say "Show me someone who wishes to discard metaphysics,
and I'll show you a metaphysician with a rival (metaphysical) system."
The metric equivalent is "Show me someone who wishes to discard
metrics (counting things), and I'll show you a metrician with a rival
Objective metrics, however, must be *validated*, and that usually
begins by initializing their weights based on their correlation with
existing (already validated, or face-valid) metrics and/or peer review
Note also that there are a-priori evaluations (research funding
proposals, research findings submittedf or publication) and
a-posteriori evaluations (research performance assessment).

New metrics need to be validated against existing, already validated
(or face-valid) metrics which in turn have to be validated against the
"gold standard" (expert judgment. Once shown to be reliable and valid,
metrics can then predict on their own, especially jointly, with
The UK RAE 2008 offers an ideal opportunity to validate a wide
spectrum of old and new metrics, jointly, field by field, against

The difference between unvalidated and validated metrics is the
difference between night and day.
The role of expert judgment will obviously remain primary in the case
of a-priori evaluations (specific research proposals and submissions
for publication) and a-posteriori evaluations (research performance
evaluation, impact studies)

I'm not sure what all these measures are, but assuming they are
countale metrics, they all need prior validation against validated or
face-valid criteria, fields by field, and preferably a large battery
of candidate metrics, validated jointly, initializing the weights of
OA will help provide us with a rich new spectrum of candidate metrics
and an open means of monitoring, validating, and fine-tuning them.
