Everyone asks themselves this question.
And everyone looks for different clues and cues to answer it.
It's primordial. We've been doing it for millions of years, because nothing is more important to our survival.
The thing is, almost no one decides the answer to the trustworthy question based on the fine print, your policies, your positions on critical issues of national importance.
We decide long, long before that.
People watch what you do. They watch with the sound off. They listen to others. They seek out clues of the tiniest sort.
Reminder: We were in tribes for a very long time before we even developed language.
