One potential reason for the lack of authoritative resources on "design thinking" is that it is still a relatively new concept. Design thinking has only gained popularity in recent years as a way to approach problem-solving, so there may not be as many experts on the subject yet. Additionally, design thinking is not a static or formulaic process, but rather a flexible approach that can be adapted to different situations. This means that there may not be one right way to do things, making it difficult to create definitive resources on the topic.
Another possibility is that design thinking is not well suited to being codified into traditional instructional resources. Unlike other fields where there is a body of knowledge to be learned, design thinking is more of an exploratory and iterative process. This means that it may be better conveyed through experiential learning or direct observation, rather than through written instructions.
Whatever the reason, the lack of authoritative resources on design thinking can be a barrier for people who are interested in learning more about the subject. However, there are some excellent introductory resources available, such as the IDEO Design Kit (https://www.designkit.org/design-thinking). Additionally, there are many knowledgeable people in the field who are happy to share their expertise, so don't be afraid to reach out and ask questions.
