Interesting research in the linked article about menu engineering that contradicts what many of us have been taught.

I would like to know more about the study though before considering it definitive, like how large was the study group, how often was the study repeated with different test subjects to see if the results were the same, and were the subjects interviewed for subjective analysis to make sure that knowing they were being studied wasn’t affecting how they scanned the menus? Has this study been peer reviewed?
