I volti della menzogna: gli indizi dell'inganno nei rapporti interpersonali

Ekman's work is fascinating, but I wonder how he determined which expressions are universal versus culturally specific. What led to these particular signals being emphasized?

Reading about how easily we can be misled by facial expressions made me question how often I trust first impressions. Has anyone experienced a moment where a quick glance changed their mind?

The book's approach to decoding emotions through faces is compelling, but I'm curious if this focus was driven by personal experience or broader research interests.
