Most of the inhibition around this task feels like it comes from the
   idea that people could read hidden information from politicians, maybe
   extract subvocal speech (ie thoughts for people who subvocalise their
   thoughts) automatically from vein contractions near mouth muscles.
   So a side project could be finding a way to automate putting together
   information indicating people's reasons for actions (another thing that
   shows thoughts).  This is not a hard task: events that happen before
   other events, paired with indications of causality, have some
   likelihood of being part of their reasons. Developing tech toward
   public and free technological "mindreading" would help people
   understand things. There's a further step where further indications of
   causaility are developed repeatedly.
   But this heartpulse goal is not focused on that.
