that is an interesting idea for marketers/retailers/advertisers to ponder. how do we communicate enthusiasm for a worthwhile product without manipulating what we know about human nature? is it unethical to place your premium products to the left of your store entrance if you know that the majority of customer flow moves in that direction? is it unethical to create beautiful displays that encourage customers to engage in "which one should i pick" as opposed to "should i pick one"? as an artist and a former shopkeeper i have struggled with these questions.
