As ice cream sales increase, the rate of drowning deaths increases. Therefore, ice cream causes drowning. Obviously, the above example is ludicrous. It completely fails to account for the time/season and the temperature. In this case, the sale of ice cream and the rate of drowning is caused by a common cause – the summer months. When it’s hot outside, you’re more likely to eat ice cream and you’re more likely to swim. As the exposure to water-based activities increases, the number of people who don’t know how to swim or who simply get in trouble while swimming also increases which results in a higher drowning rate.
