Of course it's done! For one thing, you don't need to fit your model to the full historical record. So you can use more recent data to validate models fit to older data. It's like training AI.
But yes, models fit to the full historical record can only be validated in real time.

- mirimir 8y agoHey, science is adversarial. Climate datasets are publicly available. And there are mechanisms to detect and punish cheating.
- thaumasiotes 8y agoScience as practiced is generally not adversarial. Witness the reproduction crisis.
- mirimir 8y agoWell, that's psychology, and calling it "science" is arguably iffy. I've attended a fair number of seminars in physics, biochemistry and molecular biology. In the right hands, a "dumb question" can be a deadly weapon. And if the presenter is a prospective hire, it's often all the more intense.
