Hans walked into a grocery store and saw a bunch of empty shelves in the produce section. "I knew it," he said out loud, "we've got supply chain issues. All the produce is rotting in a warehouse on the other side of the Canadian-US border." A grocery clerk overhears and says, "No, we've got plenty of supplies in the back, but we are short staffed today and haven't had time to stock the shelves." Hans replies, "Nonsense! You can just see that there are supply chain issues." Hans' mistake is: Question 14 options: a) Belief perseverance. Hans already had a belief that there were supply chain issues and isn't willing to listen to alternative explanations. b) Evidence primacy effect. Hans thinks that evidence should be transparent. c) None of the other answers are correct. d) Availability heuristic. Hans only looks for confirming evidence for his beliefs but fails to look for disconfirming evidence
