You have things backwards. One has to look at the evidence first, and then decide policy. We can't suppress research based on how one imagine it might cause policy changes if you aren't 100% sure these policies are right to begin with. No one has 100% certainty of anything.

As for educational funding, there is ample evidence it doesn't do a whole lot, but it sure costs a lot of money. Seemingly, you are committed to a policy of suppression of research that finds educational interventions doesn't work because you currently believe they work.

Private schools don't really matter much. There is evidence on this too. It's mostly genetic self-selection. Would you have suppressed this evidence too? You seem committed to a general view where suppressing research that disagrees with your current views is the right way.
