I think an argument can be made that we should have given up (figure of speech: rather, distributed most of resource to other experiments) on WIMP much sooner.

I think an argument can be made that we should have given up (figure of speech: rather, distributed most of resource to other experiments) on WIMP much sooner. These days we agree "WIMP didn't work out", but in retrospect, was it actually the most promising prospect for dark matter, even in 2010? Why was XENON a better experiment than, say, ADMX? I mean, if it were up to me I would fund both, but I think there was certain inertia and undeserved bias for WIMP.
