By dominate I mean 2 of the last 3 prizes and a fraction of recent prizes that is far larger than the fraction of physicists that work on high energy physics. (I count 6 out of 21 prizes since 1995 in high energy physics, or 28% to a community that is something like 15% of the American Physical Society). We simply haven't figured out how to recognize the more important contributions in less reductionist and more applied areas of physics. Last year's prize for semiconductor LED breakthroughs was a step in the right direction. But going back to neutrinos so quickly reflects the prize committee doesn't really get it.
So, what you're really saying is that there needs to be a minimum average amount of rest mass per Physics Nobel Prize, and the recent trend is underweight?
