    Why Tit-for-Tat works

    TFT is simple: start with cooperation, then mirror the opponent. It balances trust and protection.

    Nice

    Begins with cooperation to invite trust.

    Retaliatory

    Punishes defection immediately to prevent exploitation.

    Forgiving

    Returns to cooperation once the opponent does.

    Clear

    Predictable behavior sustains cooperation.
