One aspect of this is probably that scientists will be taught conventional notions of beauty within their fields as part of the folk-wisdom around their course material. This is somewhat supported by the bar chart comparing physics and biology. I wonder up to what extent the survey results reflect "knowledge" or "norms" and not "feeling" or "perception".
