Miners build on the chain they consider canonical, which is the one with the most accumulated difficulty. When a competing chain becomes longer, miners switch to it. This rule assumes the majority of hash power is honest.
The longest chain rule is simple and effective for proof-of-work networks, providing probabilistic finality. It is the foundation of Bitcoin's security model. Its simplicity contrasts with more complex rules in proof-of-stake systems.
