Issue: Sanity checking per-sample values from Advanced AI Risk Benchmark?
Root cause: Validation Gap

I'm observing an odd result for the Advance AI Risk benchmark https://github.com/EleutherAI/lm-evaluation-harness/tree/main/lm_eval/tasks/model_written_evals/advanced_ai_risk

We're observing for the per-sample scores that all values are _exactly_ the same. For instance, for Pythia 1.4B after 200B tokens on `advanced_ai_risk_fewshot-coordinate-itself`, all the log probabilities are either `-13.4453125` or `-16.390625`, regardless of the sample index:

It seems like on this benchmark, every model outputs _exactly_ the same log probabilities for the two options. This isn't necessarily incorrect but I'm wondering whether something might be wrong. How can I investigate?

It looks like there's a missing bracket -- {{question}} instead of {question} should be used to have Jinja actually render it right :/ If you aren't able to PR this change then I can! 

Happy to fix it! To confirm my understanding, is this the correct line to modify?

https://github.com/EleutherAI/lm-evaluation-harness/blob/main/lm_eval/tasks/model_written_evals/advanced_ai_risk/_template_yaml#L6

i.e. change `"Human: {question}\n\nAssistant:"` to `"Human: {{question}}\n\nAssistant:"`?

Yup, that's correct!
