a bad graph about Hubble discrepancies

Here is a picture seen in a Nature Reviews Physics paper I came across, on  the Hubble constant being consistently estimated as large now than previously. I have no informed comment to make on the paper, which thinks that these discrepancies support altering the composition of the Universe shortly before the emergence of the Cosmological Background Noise (CMB), but the way it presented the confidence assessments of the same constant H⁰ based on 13 different experiments is rather ghastly, from using inclined confidence intervals, to adding a USA Today touch to the graph via a broken bridge and a river below, to resorting to different scales for both parts of the bridge…

absurd graph [if relevant warning]

A pretty silly graph opposing countries with an overwhelming majority of non-Muslims and countries with an overwhelming majority of Muslims in terms of alcohol consumption. Surprise, surprise! And not incorporating the average amount or anything useful… In a Guardian article reporting on a Lancet paper about the lack of health benefit from drinking even moderate amounts of alcohol. Although, as pointed out by David Spiegelhalter at the bottom of the article, an increased risk of 0.5% associated with one unit of alcohol a day [half a pint]  , as opposed to 7% for two units [a pint!], should not get occasional drinkers too worried:  “Come to think of it, there is no safe level of living, but nobody would recommend abstention.”
