There is literature out there on these automated calling systems from years ago, and they actually studied where people are most honest. They are most honest on an automated calling system, as opposed to talking to a practitioner, so we have a high degree of confidence in the system.

If they lie to you, they lie to you, and we'll see it on their vital signs.
