This is a great point -- weighing false positives against false negatives/true positives/false positives is something we think about a lot. It's really important to get this right.

This is why, at this stage, we have a strong bias towards guiding people towards the right care provider rather than trying to replace them; it's more of an aid rather than substitute. One example of this is how some of our users have used the symptom tool with joint pain, and its helped them figure out that they should see a rheumatologist, who was then able to guide them towards the right care to treat their particular version of arthritis.

It's smart care providers like that that can really deal with the nuanced cases and make sure people minimize the risk that they miss things like a pulmonary embolism.
