The problem with this is our biases. What we learned from the Nazis is high gear when it comes to the rhetoric of both parties. I read this site as left wing when drawing comparisons to candidates. It's the truth that this organisation and others want you to know. Remember Russian collusion and some on the left still believe it.
"Ever heard the phrase, if you “repeat a lie often enough … it becomes the truth”? It’s often credited to Nazi Joseph Goebbels, one of the most notorious and malevolent propagandists in history. This law of propaganda drives much of the misinformation we find online. Our vulnerability to oft-repeated falsehoods and the “illusion of truth” effect makes it crucial to understand the common themes and narratives of viral misinformation"
They may think the claims against Biden were exaggerated and yet four years later some truth. I know in 2020 that Joe wasn't the same Joe during the Obama admin. Unfortunately, nothing is mentioned about the attacks against Trump's cognitive ability so I'll file this site as left-wing propaganda. I would love to see a site criticize both candidates then I'll consider it neutral.
"Claims that exaggerate and distort candidates’ cognitive abilities and intellect are the most frequent in our collection. This was true when President Joe Biden was the presumptive Democratic nominee running against former President Donald Trump, with many false claims attacking the candidate’s age. And the trend has continued with Vice President Kamala Harris. It’s important to note that these overall narratives are not entirely fabricated (all three politicians have had their share of public gaffes), but they appeal to our natural desire to confirm our biases, providing an exaggerated and distorted glimpse of reality in which the candidates are reduced to caricatures of themselves. Are Trump and Harris both mentally fit to be president? Our dashboard isn’t designed to answer that. But it can help to make you aware of the spate of misinformation that intends to skew your viewpoint on this question."
