Tsuei compares the process of selection to the way an office worker has to spend time in front of her wardrobe every morning choosing what color clothes to wear that day. Many people may pick them according to whim, but when selecting remedies one has to use scientific methods to weigh this "intuition."
她比喻，就像上班族每天都要在衣櫃前選擇各種顏色的服飾，很多人可能是憑感覺挑選，現在他們就要將「感覺」以科學化方式來衡量。
