Abstract:	The discovery of causal relationships from empirical data is an important problem in theory development. We investigate the use of TETRAD IV to help researcher in a theory development phase. We applied TETRAD IV, a heuristic search software that used for discovering causal effect relationship between variables based on a specific model. To performed our task, we defined two case studies. First, we re-analyse an existing model or theory using original correlation matrix data from a paper in Knowledge Sharing field. Second, we validated the existing model by conducting a survey using data from 90 respondents (Bachelor, master, PhD candidate) in the University of Twente academic setting, which pointed out Blackboard as the primary online learning tools to support teaching as well as sharing the knowledge. The results give us suprising remarks. From the first case study, TETRAD IV discovered spurious relationship in the model, which are there is no causal effect between its variables. Furthermore, using our own data, we found the same results of causal linkage as we have in the first case study. These results give the idea of what truly occurs given the real data. Thus, it is critical to explore the relationships among the variables in the model using exploratory research tools, as TETRAD IV, to aid and guide the researcher in theory development phase.
