I once worked in a building that housed a photo studio. The good news was that we often rode in the elevator with pretty, pretty models. The bad news was that they often seemed flummoxed by the elevator button panel and would hover over it, looking for the 12th floor.
Yes, human models have a reputation for acting dumb. By the same token, computer models often act dumb, too. As a result, marketers need to take caution when employing models.
It would be wrong of me to use a picture of a pretty young lady just to get clicks.
Just ask the Australian Army.
