Jev Arithmetic Rejection Bottleneck
A third-party preprint reporting a sharp drop in Jev rejection behavior when arithmetic answer menus omit the correct option.
The study uses paired arithmetic menus to compare answer-present and answer-absent conditions. This page summarizes author-reported findings and boundaries; it does not claim an identified internal model mechanism.

Paper-reported findings
- The paper reports 99% selection of the correct option when it is present, compared with 7% rejection when the correct option is absent in the main arithmetic setting.
- The boolean-verification condition is reported at 99% accuracy.
- The reported confidence threshold produces 79% rejection in answer-absent cases while retaining 97% of answer-present cases.

Method and usage
- The authors pair arithmetic questions whose option menus either contain or omit the correct answer.
- A separate boolean-verification setting checks whether the model can judge a proposed arithmetic answer.
- A confidence-threshold analysis tests a possible abstention rule on the reported outputs.
Limitations and evidence boundaries
- The tasks are synthetic arithmetic menus and may not represent broader production decisions.
- The study observes a hosted API and does not establish an internal mechanism for the reported behavior.
- No separately verifiable public code or dataset artifact was identified on the review date.
