  The method of Damage Spreading was used to simulate the influence that a
single persons' change of opionion has on the consensus opinion built up in a
population if one assumes opinions to form according to the Sznajd Model. The
results confirm the intuitive assumption that there is hardly any chance for
one person to change the consensus, that the effect of this change dies out
after a certain time and its range decreases with time. The consensus times
were compared and it turned out that the consensus can be delayed or
accelerated by this slight modification and that the amount of the difference
in the consensus times obeys a certain power law as well as the lifetime of the
effect. Moreover two scaling laws concerning temporal and spatial aspects could
be observed up to a certain size of population.
