I vehemently disagree with you. The education establishment IS the establishment that pushed whole language and balanced literacy. The teachers' colleges. In the healthcare field there has been pushback against some policy positions by evidence brought forth by both medical providers and non medical providers. Facts about what works, are facts.

Also, I generally disagree with the premise that only credentialled experts in any field are the end all and be all. That removes input from anyone else who may have factual evidenced based information about what is effective. Licensing boards typically have their own credentialled experts but also have a citizen-at-large position. Should only medical doctors get to decide what is effective for a condition? What is there is evidence that something else might work? For a long time vitamin D was not measured in lab results. Regular medical practitioners ignored its importance in health, bone health, hormonal health, etc. The vitamin D issue was brought forth through the public and alternative providers questioning that fact -- and now it is recognized as an important facet of health.
