98% of the pubic doesn't understand how to read or interpret statistical analysis.   I've had exposure in both academic training, and a decade of using this kind of date in Continuous Improvement work in manufacturing.   While I might spot some very obvious problems, a trick of how data is collected or how it is interpreted, I'm still not an 'expert'.    I can assure you most members of Congress doen't have an informed view of the risk, or value, of data collection.

It won't make much difference if Congress just uses the standard populist approach to drop the agencies.   Very few people enjoy statistical analysis, they don't care, they won't miss it.   'It's just another elitist way to get American taxpayer money.'   Capitalizing on the mistrust and envy of those that have knowledge we don't understand is a big winner for those that like populism and it's appeal to the 'average' citizen.
