Quantitative social science is not only about regression analysis or, in general, data inference. Computer simulations of social mechanisms have an over 60 years long history.

Defining and classifying quadrilaterals, though an established component of the school mathematics curriculum, appears to be a difficult topic for many learners. The reasons for such difficulties relate to the complexities in learning to analyse the attributes of different quadrilaterals and to distinguish between critical and noncritical aspects. Such learning, if it is to be effective, requir...

Academic psychology’s long love affair with the modernist program ...
Global history is the outcome of a complex but knowable dynamic process that has been operating in the human sphere for the past two million years and that will continue to operate for as long as human society exists. Underpinning this dynamic process are the laws of history. This article argues that it is possible both to model the dynamics of human history and to identify the laws that govern...
I propose to begin my paper on the logic of the social sciences with two theses which formulate the opposition between our knowledge and our ignorance. First thesis: We know a great deal. And we know not only many details of doubtful intellectual interest but also things which are of considerable practical significance and, what is even more important, which provide us with deep theoretical ins...
The turn of qualitative inquiry suggests a more open, plural conception of psychology than just the science of the mind and behavior as it is most commonly defined. Historical, ontological and epistemological binding of this conception of psychology to the positivist method of natural science may have exhausted its possibilities, and after having contributed to its prestige as a science, has no...
