Concerning BIAS, we all have that, but there are ways that a person can do a step away from applying some bias held.
You can notice, how quick and convenient a label, like antivax, how quick it gets applied, plus you can notice, how quickly the person talking switches right back off of the vax arguments, and (quickly) moves on into yet another, often unrelated shakey-facts smear.
Anti-vax, Musk involved, misogynist (billionaire). Heck,...that last 'smear' used to be the term 'millionaire'. That, by the way, is not an inflation driven switch.
In my opinion, the myriad of 'news' and talk show media hosts, that are currently worth several millions, makes that too clearly a compromised talking point.
Thus, only 'billionaire' is used, as the smear trigger word.
Point being, when you hear a grouping of trigger words, quickly and fluidly recited, you could put personal bias aside, and realize:
"Hey...that guy talking sounds like untrue propaganda!"
Maybe doesn't matter, what personal bias you hold, if you can use the observational methods.
Not perfect, but there are methods. Might be a statistics type of dynamic, to analyze without major bias.
