I want to conduct an experiment in the field of Human-Computer Interaction, where I test the perception of users about which image is better using different camera lenses. In the experiment, I take the exact same image with different lenses. The "tournament" lies in users blindly picking which image they liked until all the lenses are eliminated. I believe the methodology might have several confounders, but its design reflects the real world setting, where a lot of parameters are un-controlled. Will this qualify as a scientific experiment worth writing a scientific paper about?
