In engineering, we typically have (mostly) logical discussions on the merits of designs. There are sometimes strong opinions, but they are typically backed by non-subjective data. Subjectivity is frowned upon.

When I started getting into the arts, I was introduced to the culture of "workshopping" pieces, i.e. have my work criticized. It was disorienting at first, but the honest feedback was very useful plus it helped me develop a thick skin. It helped me get better fast.
