#91 Do the Early Galaxies observed by JWST disagree with Planck's CMB polarization measurements?
Yes, so the authors choose to disregard Planck’s CMB polarization measurements.
“Here, as a last-ditch effort, we point out that disregarding the large angular scale polarization obtained by Planck, which allows for significantly larger values of the matter clustering parameter $\sigma_8$, could lead to better agreement between Planck and JWST within the ΛCDM framework.”
