  1. We find that any two distance moduli measurements for the same galaxy
differ from each other by 2.07 times the reported one sigma uncertainty on
average.
  2. This average difference between distance moduli measurements of the same
galaxy as a multiple of reported uncertainty is growing with time of
publication, rising to 3.00 times the reported one sigma uncertainty for all
distances reported from 2014 to 2018.
  3. This average difference between distance moduli measurements of the same
galaxy as a multiple of reported one sigma uncertainty is highest for the
standard candles (3.01) including Cepheids (4.26), Type Ia Supernovae (2.85),
and Tip of the Red Giant Branch (2.82).
  4. This data points to a possible systematic underestimation of uncertainties
in extragalactic distances.
  5. The results also give a possible way out of the Hubble-Lemaitre tension by
advocating for increasing the error bars on Hubble-Lemaitre constant measured
via distance ladders of standard candles and rulers.
