There is a lottery shop on my commute. Occasionally, when I pass by after get off work, it is convenient for parking and the weather is fine. I will stop and buy 5 two-color balls for ten yuan. Apart from the monetary investment, no extra time was spent on research, knowing that lottery tickets are purely independent random events.
If you calculate the expected value, buying a lottery ticket will definitely be a loss, but like a black swan, it is meaningless to calculate the expected value for things with extremely small probability and great risk. I estimate that I invest dozens of yuan a month on average, which is not worth the coffee money for a week. The impact on my life is negligible, but if I get hit, I can change my life.
In addition to the extremely low monetary cost, there is no time cost invested. Initially, there will be emotional costs (there will be expectations), and now there is basically no psychological expectation, and it really does not affect daily life at all.
But like the old man in the article, a pension of more than 6,000 yuan a month, 4,000 yuan to buy lottery tickets, and a lot of time to study the so-called trends are not desirable.
