Abstract:
In this brief essay I reminisce on the ideas I encountered in Lev Vygotsky's lectures on pedology as an undergraduate student at Moscow State University in the USSR. Some of these ideas have been reliably stored in my professional memory and have influenced how my colleagues and I have approached the assessment of IQ (or general cognitive abilities) in countries other than the ones in which they were developed. Whereas the essay is autobiographical in nature, it attempts to make a generalizable point that spreading the wealth of existing knowledge, principles, and practice is as central to the progress of science as generating new knowledge.
