Graphic design, and the general issue of design, is important for many different reasons. Everyone likes to look and admire aesthetically pleasing design and beauty. I believe it's something innate. Research has shown that even babies will look longer at a beautiful face. Beauty captures and holds our attention; it seems to entrance us, even if for a moment.
Objects and graphics that are designed well charm their way into our minds. A great design of an object, website or something that is interactive goes beyond the aesthetics but is also designed well in usability. The best designs incorporate great aesthetic value with a heightened user-experience.
We are the reason great design is important. We are the ones that will pay more for a designer handbag or are sold by an iPhone billboard. We stare at great advertisements; they capture our attention. They move us emotionally or touch a chord within. We cannot deny the power of awesome graphic design or any gorgeous design.
