Hawaii and other island cultures have a very distant relationship with modern mental healthcare…

Culturally “hearing the ancestors” isn’t always a bad thing and “there’s no harm in listening” is common communal advice. As such people just don’t see a medical professional until law enforcement is involved. With the dad being a Senator, that takes something big or public like this.

But, when most people are referring to “voices” they mean more like gut instincts, those populations still experience normal rates of mental illness just like everyone. So when those people hear the advice “listen to the voices and think about what they’re saying” is literal dangerous advice.

The Gabbord family seems to be Vaishnava, and I don’t know how that religion views the concept. But like I said it’s a cultural thing and usually sticks around after religious conversions, that’s how important it is in oceanic cultures.
