In everyday life we have make many decisions. We can gather exhaustive information relevant to the topic, or we can use a mental shortcut or “heuristic”. Since the 1970s psychologists have studied not just how we think, but how our thinking fails. How limits to human memory, processing speed and other cognitive capacities shape our problem solving, and creativity. In this episode of Psychology in Mind we take a look at the problem solving shortcuts native to the human mind, and examine how they both limit our ability to think rationally and enable us to think faster than we otherwise could.
