My father is a smart man. He spent many years of his life listening to people’s arguments, first as assistant district lawyer and then as a judge. My dad knows rubbish rhetoric when he hears it.

One of his favorite phrases is: “If you don’t have anything smart to say, then don’t say it at all.” Yet, for all of his legal training and life experience, he can’t help but keep talking about the Mega Millions jackpot.

We all know the odds(几率)of winning the jackpot this evening with one ticket are extraordinarily low ... 1 in 175, 711, 536, to be exact. Still, people go out and buy hundreds of tickets with the hopes of becoming wealthier beyond their dreams. Why? There are two possible explanations for this “irrationality”(不理智).

One idea is that the way we calculate odds in our heads has nothing to do with mathematical odds in the traditional sense. We don’t go to the mathematical odds table and say, “Well, this would be a terrible investment. I think I’m better off putting my money in the bank!” Rather, it has everything with the ability to picture an event happening.

My father, for instance, watches the news every night and sees people winning the lottery( * * ). Therefore, he thinks the chance of him winning the lottery is much higher than they actually are.

The second thought is that the expected effect of playing cannot be represented merely by the odds. My father and, I’m sure, others get a thrill from the mere idea of winning. He loves imagining what it would be like to actually win and losing doesn’t really affect him. Sure, he’s disappointed, but it’s “better to have loved and lost than never to have loved at all.” When you combine the utility of thinking you can win with the utility of actually winning (no matter how small the chance of that occurring), it’s worth it for many people to spend the one dollar on a ticket.

My analysis is that both factors are at play in taking a chance on the lottery. My father and others really do underestimate the odds of winning, but the thrill of participation is not denied by a realistic assessment of the odds. Still, I would probably put my finger on the scale for the first explanation.

All told, a review of the odds of other events happening confirms that there just aren’t many events that occur with less frequency than your winning the Mega Millions jackpot. Look at the graph below, you may understand some:

In many ways, it’s like the lottery, something that features often on television and about which people fantasize, but that rarely happens.

So, when you watch, along with my Pa, to see if your lucky number is drawn this evening, keep in mind three things: that your number almost certainly won’t come up; that you are still going to have fun; and that, finally, a lot of other things are more likely to happen—but getting eaten by a shark isn’t one of them.
