The author clarifies that their experiment only tested a few conditioning variants, so it is not an exhaustive study.
They say they can rerun the benchmark if readers suggest a conditioning scheme that should fix the issue, and they point to the full writeup plus the related papers, Blind faith in text and Greedy agents. The underlying claim remains that a prior can overwhelm image evidence in frontier VLMs.
