Although availability heuristics have some benefits‚ it also has some disadvantages that can

Researchers and theorists have developed categories of such errors: representativeness heuristics‚ availability heuristics‚ memory and hindsight biases‚ etc. . . . In other words‚ to err is human. In 1957‚ Festinger identified another phenomenon in human cognition--cognitive dissonance. Festinger theorized that humans experience negative emotions when
