Based on the theory of the Norm of Reciprocity (NOR), this study is focused on an individual’s data sharing behavior with respect to academic research by investigating their attitude towards data sharing and external funding. A measure was developed for data sharing, and the Adjusted Eisenberger Scale was attuned for measuring the Norm of Reciprocity. The measures were distributed by a random numbers generator to academic researchers at research intensive universities. The results show that NOR does not correlate with data sharing. There was also a negative correlation between scientists’ willingness to share data and external funding. The results are inconsistent with the psychological theory.
