@bythewell - Structuralism is useful for learning general ideas about something. Most people outside of self help books wouldn't be able to base their lives around making decisions according to a decision making structure.
Structuralism is good for things like an ethical decision making model which can be used by a committee so that they remain consistent and fair with each case they consider.
Or maybe a student could use a career decision making model in order to pick a college or a particular class.
As long as they don't follow the steps blindly it can be a very useful tool.
