Information functions as social currency in Brazilian relationships. When someone shares valuable information with you—an opportunity, a warning, inside knowledge—they are giving you something of value and creating a kind of relational debt. You are expected to reciprocate over time, sharing what you learn that might benefit them.
This exchange builds and maintains relationships; it is how people demonstrate that they are invested in each other’s success. Someone who only takes information without sharing is seen as selfish and may find themselves cut off. Be generous with information you can share. Understand that when Brazilians share with you, they expect reciprocity—not necessarily immediately, but over time.
