A network of trust can be mined or it can be fed. The people inside it decide which, and they decide it one introduction at a time.
I make lasagna, and a friend of mine fishes. Neither of us eats what we make. It goes to someone else. I send a hello text most days to different groups of people, before anyone has asked. The friends I keep close do the same sort of thing. In my own account, that is a filter as much as a habit: it is how I tell who is actually close.
There is a difference between a stance and a coat. A coat is generosity put on when it costs nothing. A stance is who someone is when it does cost. A restaurant operator I know learned Spanish so he could talk with his own restaurant staff. No one required it, and it was not a hobby. He needed to serve the people he worked with, and he did the work.
That is character. It is also structure. A network of trust is a shared stock, and every member either draws it down or builds it up. Taking spends trust. An introduction made without a price, a check written early, a room opened for someone who was not in it, each of these puts trust back. A network that is only taken from empties, and the members who are most connected can empty it fastest.
The Green Book is a case where adding was the whole mechanism. Victor Hugo Green, a Harlem postal carrier, published it from 1936 as a guide to places that would serve African American travelers. He filled it with field reports from fellow postal carriers and paid readers who sent in useful information. Standard Oil sponsored it, so it was sold at Esso stations across the country, and it reached roughly 15,000 copies a year. After he died in 1960 his wife, Alma, kept publishing until 1966. [1] In my reading, a guide like that lasts only while the people in it keep adding to it. The moment contributors turn into consumers, the listings go stale, and the stale ones are the ones that put a traveler in danger.
For an investor, this is a diligence question about any well-connected founder or fund. Ask what the person has done with their position in the network. Who did they introduce without being asked? Who did they back before it paid? A central position is an asset, and its holder can spend it or feed it. Which of the two they did shows up in how others talk about them when they leave the room.
