Thank you for the clearification! and thank you for taking the time to find an example, it did help me to understand your point!
I understand your point of view of finding a research/program fit. I think you arguement makes a lot of sense. I do see how it can benifit the student as well as the school. However, I think your approach wouldn't be a good fit for me. I am not sure if this puts me into a disadvantage. But I think at my age (21) there is too much that I don't know about marketing and the world. So I don't think I am in the position to argue that I have a very specific interest or a problem I want to solve. But one thing I do know is my love for research. I enjoy the process, the thinking involoved, and the findings. This might sound geniric, but I just want to understand the world and people around me through research. At first, I thought psychology would be the way to go, then later I found that I don't enjoy the type of abstract thinking that's involved in psychology research and marketing (CB) provides a context to the effects we study, which helps me think much more clearly. For that reason, when I heard that there is a possibility of doing research for a living, I pursued that opportunity immediately. Put it in another way, I guess I am not pursing a phd degree to solve a problem, I am pursing this education to gain the skillset to conduct good research and have the qulification to do research for a living. After hearing from you, I understand now that this probably will put me at a disadvantage to some people. But I guess the best thing I can do is to communicate myslef better in my application (by being more specific, talking about my interest by listing a problem to make the topic more engaging, and avoiding "arguing with the professors" ) and keep my fingers crossed.
Lol If I apply to your school and you are making the admission decisions, you probably wouldn't accept me. But I hope some schools will.
Thank you for your advice and your help! You have provided me with informations and views that I have never thought of, so I really aprreciate you taking your time and sharing your wisdom with me. I will certainly think more about school fit going forward, especially on the elements you mentioned, and again thank you for your time! I really appreciate it.
