A new paper published on arXiv details a phenomenon in galactic archaeology where statistical inference can become 'stable but wrong.' Researchers found that in reconstructing the Milky Way's formation history using stellar ages, observational quality can introduce systematic biases. Specifically, a region in the signal-to-noise ratio and parallax precision parameter space leads to inferred formation timescales that are offset by 0.5-1 Gyr from independent measurements, despite low statistical uncertainties.
