You might want to get the "Hacker News Enhancement Suite" extension. It's incredibly useful for cases like this, for instance I have tagged Animats (the creator of this sub thread) as "faux expert" after reading some of his crypto posts (a topic I know something about) that were written as if he was an expert, but completely and dangerously wrong.

Not knowing anything about chemistry, I would've been inclined to believe his post if it wasn't for the Hacker News extension suite, and I can read from someone who actually knows the field

If their recently-googled skepticism is accurate, then I don't care how cursory it is - it saves me the five minutes of looking up the same sources myself.
