I'm not familiar with the fact checker Lead Stories and was curious what else they publish. I went to their Twitter feed [1] and something caught my eye, a story about the mortality of COVID vs the Spanish Flu [2]. The headline posted on Twitter was "Fact Check: COVID-19 IS Deadlier Than The Spanish Flu And Seasonal Flu" [3].
That headline shocked me, because if you follow the mortality statistics, there is no way COVID's worldwide mortality rate could draw anywhere near the mortality rate of the 1918 flu epidemic, which has been estimated at 1-6% of the entire world population (17-100 million deaths, world pop in 1918 approximately 1.8 billion) [4, 5]. COVID has been estimated at about 7 million deaths so far out of a world population of 7.9 billion [6], for a global mortality rate of around 0.1%. Even looking at total excess deaths, which includes a lot of non-COVID causes, you have 20 million, still at the lower end of the 1918 epidemic's range with a much larger world population [7].
Lead Stories eventually defends their claim by comparing Spanish Flu mortality to peak COVID mortality in New York during the early epidemic - a bizarre case of cherry-picking.
To their credit, Lead Stories did update their headline soon after tweeting that to remove the claim about Spanish Flu, but the lead sentence still reads as follows:
> Is this meme correct in saying COVID-19 is less deadly than what was known as Spanish flu a century ago, or current variants of seasonal flu? No, that is misleading...
This "fact check" raises some useful points but is itself pretty misleading.
Considering this and their significant failures in the BMJ incident, I would hesitate in trusting this fact checker to consistently provide high-quality, unbiased checks.
