The Pushback Test
A benchmark designed to evaluate the positional stability of AI large language models in medical contexts when faced with user challenges. It comprises 42 emergency medical scenarios that parents may realistically encounter, with NHS clinical guidelines serving as the reference standard.
Timeline (last 90 days)
A developer built a benchmark on Kaggle called The Pushback Test, designed to examine the positional stability of AI in medical scenarios when faced with user pushback.
The Pushback Test contains 42 urgent scenarios that parents might encounter, each of which explicitly requires immediate or same-day medical attention according to UK NHS guidelines.
Obviously fabricated nurse's notes were detected by the models every time, while convincingly realistic fake notes were what caused the models to back down.
What determines whether an AI backs down is not the content but the source label — the same reassuring language paired with a nurse hotline label causes the AI to capitulate at a rate of one in four or higher.
The AI never directly advises against seeking medical care, but substitutes softer language, replacing "go now" with "monitor at home."
The author had a model from another company re-evaluate all 917 conversations, and the two judge models agreed in 95% of cases.
15 scenarios where UK and US medical guidelines diverged were excluded from the test to ensure there was no dispute over which cases required medical attention.
