Sunk Cost Fallacy

Examples

• A football team continues to play a bad quarterback because he was acquired with a high draft pick.
• Continuing to watch a movie you're not enjoying because "I've already invested 45 minutes in it" rather than cutting your losses and doing something more enjoyable.
• We've already invested $2 million" instead of evaluating its future prospects independently of past investments.
