    Modelling and Simulation in the Social Sciences from the Philosophy of Science Point of View
    with R. Hegselmann and Klaus G. Troitzsch
    Springer Verlag. 1996.
    Model building in the social sciences can increasingly rely on well elaborated formal theories. At the same time inexpensive large computational capacities are now available. Both make computer-based model building and simulation possible in social science, whose central aim is in particular an understanding of social dynamics. Such social dynamics refer to public opinion formation, partner choice, strategy decisions in social dilemma situations and much more. In the context of such modelling ap…Read more

    Is fluctuating asymmetry a signal or a Marker of genetic fitness?
    Behavioral and Brain Sciences 23 (4): 617-618. 2000.
    Fluctuating asymmetry is more a signal of genetic fitness than a marker observable only to the researcher. Hence, it has to be demonstrated that low FA is an honest signal of genetic quality; this has not been demonstrated in Gangestad & Simpson's otherwise useful review.

    Aggressiveness and dominance
    Behavioral and Brain Sciences 21 (3): 381-382. 1998.
    Aggressiveness is a vital component of dominating behavior. We must distinguish adaptive from nonadaptive aggression and must control for skills, intelligence, appropriate context variables, and – most important – whether the aggression displayed was actually suitable for improving a subject's social status. If we do, we may find a consistent positive correlation between adaptive aggressiveness and testosterone.
