Research on public value is inevitable interdisciplinary in its nature due to its aim and purpose. Both philosophical and empirical approaches are necessary to conduct such research in a successful manner. In the present paper, I intend to discuss the importance of empirical approaches in research on public values, particularly psychological and neuroscientific approaches with concrete examples. I proposed that such empirical approaches are essential in better understanding the processes and mechanisms associated with how people address issues engaging in public (...) value in the modern society. Also, I overviewed how the psychological and neuroscientific approaches contribute to practical aspects related to public value, such as policy making and education. Based on the aforementioned points, I briefly discussed directions for future research in research on public value as an interdisciplinary field. (shrink)
