We are thrilled to officially launch the Consensus Meter on February 1st, 2023.

For “Yes/No” questions, the Consensus Meter uses large language models to instantly classify the results as indicating “yes”, “no” or “possibly” in a clean, aggregated interface.

The meter will run over the first 20 results, and will only classify answers that our models believe are relevant enough to your question.

This article will specifically cover the guardrails we have baked into this feature along with all of the extremely important limitations the current feature has

For more on why built this feature and where we are going, see our blog here: Introducing the Consensus Meter


We are as excited as anybody about the future of the AI-powered information space. However, we also want to ensure that the powerful features we release are built thoughtfully, ethically, and with guardrails in place to further assist in delivering good information.

Here are a few ways that we are trying to put guardrails on the Consensus Meter:

  • No black boxesall the results that power the Consensus Meter can be seen directly below its interface with corresponding tags indicating how they were classified. Our model is far from perfect, and we want to give users full transparency into what results power the meter.
  • Our results are extracted, not generatedmost LLM-powered products are generative, meaning the AI is actually creating text. Unfortunately, these models sometimes outright hallucinate. To help mitigate this, the results that power the Consensus Meter are all extracted word-for-word quotes from papers.
  • Relevancy thresholdingif our models do not think the results are relevant enough to answer your question, we will exclude them from our analysis. Additionally, if our classifier model is not confident enough in what direction an answer leans, we won’t force a prediction and will also exclude it from our analysis.


But – there are still plenty of limitations and this feature (and all other features) will continually be a work in progress.

A few limitations to call out:

  • The model will incorrectly classify results – we have worked hard to give our model loads and loads of examples to learn from, but it is not infallible. By our calculations, our model will incorrectly classify results 10% of the time. This is more likely for confusing results like claims that are written with a double-negative, or other convoluting language.
  • Specific nuance is missing one of the biggest limitations–that we are currently working to address–is that this feature does not always account for details included in the original question. For instance, if you ask “is ibuprofen safe for adult consumption” and the potential result reads “We found that ibuprofen was safe and well tolerated in children”, our model may classify that result as “yes”.
  • Research quality is not a part of the analysis – another limitation that we cannot wait to address! Currently, each claim counts the same on the roll-up interface regardless if it comes from a meta-analysis or an n =1 case report. Not all research is created equal and future versions of this feature will take that into account.
  • We do not have access to all research – the Consensus database includes north of 150 million peer-reviewed papers. While this represents significant coverage, there is plenty of amazing research that we do have access to. The meter is just a snapshot of some of the relevant research that we have access to, not a fully-comprehensive look into all of the research regarding your question.


The Consensus Meter is in Beta and we need your help to improve it! If you see any answers misclassified, please let us know by either:

  • Opening a support ticket in the chat widget
  • Or sending an email to

Please include the following 2 pieces of information in your feedback:

  1. The link to your query (ex:
  2. What was incorrect? (ex: The 3rd answer “Results show zinc is effective…” should be classified as Yes.)

To see it in action, try asking a yes/no question like:
