One considers the chaotic behaviour of the Bianchi IX cosmological models. The Lyapunov exponent \(\lambda\) is numerically calculated. It is shown that instead of converging to a constant value, it decreases steadily. One uses short-time averages, and it is shown that the usual method of calculating \(\lambda\) is invalid in the case of a cosmological model.
