Isn't this also related to how the vaccines-cause-autism conversation started? The study involved only had a handful of subjects (a few of which were very unqualified), and then a big important journal (The Lancet IIRC) picked it up for the novelty.
The article mentions attention economy as in media, TikTok, etc playing a role before "community assessment." But it's not like scientists don't also gravitate towards the new shiny thing in their own ways.
