Given that generic public finances science being done, a reasonable explanation is expected when it is being requested. Perhaps if scientific community put forward 10% of their time explaining importance and fun aspects of the research that they do - they could expect a raise in the level of funding.
The reasonable explanation will be offered when the research is published - no researcher has time to sit down and explain every anomalous data point to the public.
It would take much more than 10% of a researcher's time to explain research concepts in a way that would let the public truly understand it. Otherwise they are just giving out meaningless soundbites that will be misinterpreted.
