Gambling with Statistics vs Economics

I've heard a lot of colleagues say "As a statistician I cannot gamble", and they are completely right. As a statistician you should never gamble because statistically you will loose money on average. By that logic you can also never buy any type of insurance; in fact you could never really buy anything because on average you will loose money. What is important in all these situations is the utility or usefulness you get from the money you spent.

For instance if you buy a chocolate bar for a dollar you are loosing money in two ways, for the materials and for the labour. If you made it yourself it would cost a fraction of what you paid for it, but then again it would take time. Maybe to you an hour at your day job would make more money than the money you would save making a chocolate bar, so on balance you are saving money by paying for the time you saved.

When we gamble or buy something like insurance we are paying instead for pleasure or security (which in essence is a form of pleasure). Many things we pay for don't directly save us money like the chocolate bar but bring us pleasure and allow us to be more relaxed and therefore more productive, like going to a concert or playing a sport. Of course we can gain other types of utility from these activities lie networking and skills building, but they aren't really applicable to gambling. What it really comes down to is how much utility do you get from gambling? If you don't find it fun then don't go to the concert. 

The main problem of gambling is when the utility of playing surpasses the actual value to a person. If gambling is the one thing that makes you the happiest spending some of your income is no worse than getting a pass to the ski hills or playing paintball. Money in, pleasure out, that makes it possible to make more money. But just like any activity, if it completely drains your account and leaves you with nothing it's an addiction and does nothing to boost your morale. 

So what could be a better gift at christmas. Most children only spend a few minutes playing with most of their gifts anyway so why not buy them a lottery ticket. For many kids the thrill of a scratch ticket it equal if not more than a kinder egg, and they cost about the same, and that the lottery ticket has also a small probability of returning some or all of their money. Of course if you want a meaningful long lasting gift I would steer clear of the lottery tickets. It's all about the cost, is it worth it?

So instead of telling people how you don't gamble because it's statistically useless, tell them you take no pleasure out of gambling and therefore get no utility making it valueless to you. Because if some people didn't get pleasure out of gambling that first monkey would have never gambled leaving the trees in the first place
