Seligman realized that when he placed dogs into an inescapable environment and administered electric shocks the dog eventually stopped trying to escape. If the dog was placed into an environment where it could escape and given shocks it would still not try to escape. It learned to give-up. This has had a major impact on human psychology.

After time passes they quit trying to prove an ROI and suffer the consequences of Learned Marketing Helplessness.
