^ For tutorial dialogue of wild animal suffering and its alleviation from a secular standpoint see:
Experiments of methodological high-quality and dependability have discovered that some high-Status journals including Nature "publish drastically substandard buildings", and overall "reliability of released investigation will work in several fields can be reducing with growing journal rank".[39]

The HotBits services at Fourmilab in Switzerland, which operated from 1996-2022, was an outstanding example of a random selection generator that made use of this technique.
In 2017, Nature revealed an editorial entitled "Taking away Statues of Historic figures dangers whitewashing heritage: Science ought to acknowledge errors because it marks its earlier".
