Pair Programming

Biological Parallel

DNA replication employs continuous error-checking: DNA polymerase proofreads each nucleotide insertion in real-time, achieving error rates of one mistake per billion bases. Pair programming implements the same dual-process architecture—one navigator thinking strategically while one driver executes tactically, with continuous mutual verification. The cost of real-time error correction is vastly lower than the cost of finding and fixing errors after they've propagated through the codebase, just as DNA repair during replication prevents catastrophic mutations.
