On a recent trip to Las Vegas, I sat in front of a slot machine and fed that blasted thing more than it was giving back. Even though I was losing at the time, I found myself unable to walk away and continued to bet one "pull" after another. A tidy profit that I'd made at the roulette table soon dwindled down to nothing. When I made my last bet, I looked around the casino floor at the hundreds of others who sat there doing the exact same thing. I wondered, with the odds so stacked against winning at slots, how did Vegas keep us playing until our money was gone? It had to be more than just blind greed throwing dollar after dollar into the slot machine in hopes that the big jackpot was just a pull away. Then, suddenly, I watched the machine next to me coax another gambler into playing. Only then did I see that the machine itself was motivating us to play. It was using techniques that kept human beings seated for hours while it slowly took their money. It motivated them. It motivated them using strategies that many managers should be willing to pay to learn.
