The Anatoly Dyatlov meme originates from the 2019 HBO miniseries 'Chernobyl,' featuring actor Paul Ritter as the deputy chief engineer of the power plant. The meme primarily focuses on Dyatlov's stubborn refusal to accept the severity of the nuclear disaster, most notably his dismissive assessment of '3.6 roentgen—not great, not terrible.' This phrase, along with his adamant denial of seeing graphite on the ground, has become a universal shorthand for administrative hubris, corporate gaslighting, and the comical downplaying of catastrophic situations. It is frequently used in modern internet culture to mock someone who refuses to acknowledge a blatant failure or an obvious truth staring them in the face.
