Dissertation consideration 2

My next topic for consideration is centred around the subjectivity of graphic design. I want to investigate if good design is as a result of design form and function or whether it comes down to individual likes and preferences:

Can “Good Design” Be Objectively Defined, or Is It Always a Matter of Opinion?

To consider this question I would research subjective design versus objective design and compare relevant cast studies to reach a conclusion on whether design can be measurable or only interpretive.
