How do scientists—especially those who conduct research syntheses—and the public benefit from Open Science? Where does psychology currently stand in terms of implementing and valuing Open Science practices? This talk will discuss the opportunities of Open Science (esp. Open Data, Open Material, Open Access) in the context of research syntheses by providing hands-on examples. Moreover, this talk presents how Open Science not only benefits the gathering of scientific knowledge and the scientific community as a whole, but also serves the broader society. Furthermore, special emphasis will be given to how Open Science can help Early Career Researchers to shape their scientific careers and to stimulate fruitful collaborations. I will end with a hopeful view of where the future of research synthesis in psychology may be headed.
