The effort to establish psychology as a bona fide science has been associated with a simplistic and incorrect picture of psychology as evolving from methodologies and practices in physics and "other sciences," and being far removed and completely separate from the humanities and arts. Introductory psychology texts routinely present this view of psychology (Dunstan & Moghaddam, 2016). However, the claim that the roots of experimental psychology are to be found in 19th-century physics and related sciences is misleading (Winston & Blais, 1996) and has negative implications for all of psychology, including peace psychology.The roots of experimental psychology actually go back to the scientific revolution underway from the 15th and 16th centuries, and are to be found in early modern literature and specifically thought experiments, which provide imagined demonstrations or tests of particular hypotheses about human behavior, such as in Shakespeare's plays (Moghaddam, 2021). In an analysis of Shakespeare's thought experiments, we find both tightly controlled thought experiments that might have been carried out in a 21st-century psychology laboratory, and less tightly controlled field experiments on the power of context (Moghaddam, 2021). Thought experiments were integral to the ideas of both Shakespeare and other thinkers in his era, such as Galileo Galilei (1564-1642). The most famous of Galileo's thought experiments revealed the invalid nature of the Aristotelian view that heavier objects fall faster than light ones. Thought experiments play a central role in the research of Charles Darwin (1809-1882) and other great scientists. Albert Einstein (1879Einstein ( -1955, probably the leading scientist of the modern era, relied almost entirely on thought experiments for the development of his ideas. Thus, thought experiments represent a bridge between science and other disciplines, including literature.Through thought experiments, the roots of experimental psychology can be found in early modern English, as demonstrated in Shakespeare's plays (Moghaddam, 2021).The attempt to position experimental psychology as strictly associated with "physics and other sciences," and completely separate from the arts and humanities, is not only historically incorrect (Moghaddam, 2021), but also harmful to the efforts of research and practicing psychologists. For example, peace psychologists active in the field have to go beyond the limitations of traditional laboratory experiments, and employ thought experiments and intuitive understandings and propositions, in order to progress toward practical solutions (such as in conflict resolution). Rather than position psychology as being modeled on 19th-century physics and completely removed from "nonsciences," it would be far more fruitful to adopt a more integrated, interconnected view of human knowledge, where at the frontiers the "different disciplines" have a great deal in common, particularly through thought experiments (Moghaddam, 2021). This is an important and relevant point for the traini...
