Good catch. I think sponsorships should always be disclosed in the abstract or introduction.
It was the first sentence of the second paragraph of the introduction.
Honestly not worth reading it at all knowing this.
And right below that:
"Author disclosures: P. G. Williams, no conflicts of interest."
Wouldn't the conflict of interest be that this person was paid by lobbyists for the article he wrote? I mean, I wonder what his defs. of conflicts of interest are? Sounds like they don't match mine.
Great eye. It should be part of public education to teach kids to question both whether or not something is true, and, "who benefits from me believing this is true"?
