This is not quite an answer to your question, but: Wherever you're starting, it's really important to check whether the person behind the information source is qualified to speak authoritatively on the topic and whether they have financial incentives to promote something they're saying.
Ask questions like: Is there a specific human or HIGHLY respected organization (not a random business) putting their name behind the information? Is that human actually qualified in the field/subject they're talking about? ("They wrote a book on it" or "They have a PhD in an unspecified field" isn't good enough on its own.) Are they recommending a product or service that they sell? Those filters aren't enough on their own, but they will help you avoid a lot of nonsense.
You probably already knew this stuff, but I need to continually remind myself to check these things, and maybe this reminder will help you too.
