This is a good question to raise, but the question is mostly academic thought gymnastics. Would it be great if policies and decisions were based on facts? Sure

This is a good question to raise, but the question is mostly academic thought gymnastics. Would it be great if policies and decisions were based on facts? Sure it would. But the real problem is not the distinction between "fact" and "very high confidence". The real problem is that is the misuse of dubious correlations to justify agendas. Politics, economics, personal decisions etc. We don't have a crisis of scientific facts. We have a replication crisis. And because of that, a lot of bogus science goes unnoticed and makes way WAY larger impact than it should.
