Taking in data blindly ... is garbage in, garbage out. You have to have a "world model" to filter the data with. Is the "world model" validated by the data? If so, and some data is contrary, but doesn't invalidate the "world model", then that data is false (aka noise or propaganda). Of course, having a "world model", means "philosophy" which most people here deny, because of their nihilistic materialism. And there is a constant flow of new data.
Example: HCQ. Is it part of a Covid treatment or not? Oh, if my model is TDS, and Trump mentions HCQ, then it must be poison, right? Well, it could have been. But new data showed that it works as part of a Covid treatment. Smart people then recalibrate and build a revised model. Crazy people decide that HCQ success is propaganda ;-)
