Who do you trust most and who trusts you most?
By just looking at one factor, I could make a pretty good guess.
The number of times people have direct interactions with each other gives a surprisingly accurate prediction of their level of trust in one another.
How often do you have interactions with your family? Friends? Colleagues? Customers?
Who we know and the frequency of our interactions maps to who we trust. And one of the reasons trust is so valuable is because it takes time.
