Shoshin or “beginner’s mind” is a concept from Zen Buddhism and refers to an attitude of openness, enthusiasm, and lack of preconceptions, similar to that of a beginner. The practice of Shoshin serves as a counter to the hubris and closed-mindedness often associated with considering oneself an expert.
Shoshin also acts as an antidote to the “Einstellung effect”, which is a predisposition to solve a particular problem in a specific way, even if better or more appropriate methods exist. It is the negative effect of previous experience when approaching new problems.
