# Early signals

How Sensa spots problems.

**Early signals** highlight two things:

-   A theme that fell by 0.3 or more in a group since the last pulse.
-   A theme scoring below 3.4 out of 5 overall.

A signal is a prompt to talk to people, not a diagnosis. Groups too small to show are left out.
