I came across a post by Damian Synadinos, dating from August 2017, entitled Thinking about Beliefs. He explores the idea of belief systems; how they come to be, how people interpret them, how adopters implement them, various things that can go right or wrong when people apply them, and what can happen when we question our belief systems.
After presenting a general model of belief systems, Damian goes on to illustrate his ideas by describing how he set out to question his beliefs regarding software testing; that is, his belief system around his work. He discovered that some of his previously-held beliefs about software testing seemed sound while others had room for improvement, once he began to question them systematically.
