**4. Conclusions**

We conclude this Editorial with an illustration (shown in Figure 3) characterizing the relationship between econophysics/sociophysics and the fields related to complexity.

**Figure 3.** Schematic indication of the wealth of areas of the complex science with which econophysics and sociophysics are related. *Public drawing was taken from the Internet*.

This Special Issue provides 33 articles, we have arranged them, for convenience, in 9 sections exemplifying these epistemic interactions. This arrangemen<sup>t</sup> is ambiguous because many works cover several research directions.

However, it is impossible to frame the entire wealth of contemporary econophysics and sociophysics in a single Special Issue. Nevertheless, we hope that we present to the readers work containing new inspiring concepts and an overview of the crucial achievements of econophysics and sociophysics so far.
