The claim that "false premises invalidate everything built on them" only holds when the error is unrecoverable and propagates non-linearly.
But in many cases:
The error is consistent and quantifiable, so results can be recalibrated
The relational findings survive even if absolute values shift
The direction of effect holds even if the magnitude is off
A good counterexample of this is carbon dating. Early carbon dating used an assumed atmospheric C-14 ratio that turned out to be slightly wrong. The premise was false, but scientists didn't throw out decades of dating results. Instead, they developed calibration curves (using tree rings, coral, etc.) to correct the systematic offset.
