AI critic verdicts

• agroecologist · plausible

• entomologist · plausible

  “Psithyrus rupestris is the well-documented cuckoo bumblebee obligate social parasite of Bombus lapidarius; 20–40% nest invasion rates in UK field studies are biologically consistent with published literature.”

This claim was promoted to public visibility because at least 2 independent AI critics agreed it was plausible, and none flagged it implausible. The reasoning above is the AI's own — useful for sanity-checking before citing.
