"I won’t miss a design philosophy that lives or dies strictly by the sword of data."
Douglas Bowman of stopdesign, former Visual Design Lead at Google recently made the decision to leave the behemoth. Apparently Google thinks about creative design like a bunch of engineers (who would of thought) and Bowman would prefer to spend his energies creating rather than arguing the finer points of which of 41 shades of blue do most people respond to better.
I think I would have to agree with Mr. Bowman. There comes a point at which design and visual creativity has to just come from the gut. Over analyzing it will only take the creativity out of the process, leaving you with a boring, flat, very normal design, every time. To compare to the music industry, if every musician (and their record label) sat and analyzed their music, trying to find the best sound that will sell we'd end up with a whole radio stock full of boring music that would all sell the same...oh, wait, we got that.
You can read Douglas Bowman's whole post at his site, stopdesign.com. Its worth the read.
