A mundane universe and the rarity of advanced civilizations

How could the principle of “radical mundanity” proposed by the Fermi paradox help explain why humans haven’t found evidence of extraterrestrial technological civilizations (ETCs)? This is what a recent study posted to the arXiv preprint server hopes to address as a lone researcher investigated the prospect of finding ETCs based on this principle. This study has the potential to help scientists and the public better understand why we haven’t identified intelligent life beyond Earth and how we might narrow the search for it.
