“Researchers who have studied SMART goals and other structured methods of choosing objectives say this isn’t unusual. Such systems, though useful, can sometimes trigger our need for closure in counterproductive ways. Aims such as SMART goals “can cause [a] person to have tunnel vision, to focus more on expanding effort to get immediate results,” Locke and Latham wrote in 1990. Experiments have shown that people with SMART goals are more likely to seize on the easiest tasks, to become obsessed with finishing projects, and to freeze on priorities once a goal has been set. “You get into this mindset where crossing things off your to-do list becomes more important than asking yourself if you’re doing the right things,” said Latham.”
