Donald Norman's quote recommends that the typical individual is not really proficient when it comes to develop. This might be interpreted in a couple of various ways. Firstly, it could mean that the typical individual does not have the technical knowledge and abilities to develop visually pleasing styles. Second of all, it might suggest that the average person does not have the innovative vision and creativity to come up with ingenious styles. Finally, it could imply that the average individual lacks the experience and proficiency to develop designs that are practical and useful. In any case, Norman's quote implies that style is a skill that requires a specific level of knowledge and knowledge, which the typical person is not up to the job.
