There have been times when I was completely honest and transparent even in the face of short term costs specifically because I knew it would help build my reputation for honesty. I assume I'm not the only one who's done this, so I wouldn't take it as a sign that a person is 100% trustworthy. On the other hand, a pattern of honesty probably is the best indicator of an honest person.
