Gender is a social construct. This is confusing because it has its basis in biology. When it comes to gender, what’s the relationship between societal norms and biology? Gender is a social construct because, while it’s related to your sex, it’s not based on your biology.

What is the law of small numbers? How does ignoring it lead to biased decision-making? The law of small numbers is the bias of making generalizations from a small sample size. In truth, the smaller your sample size, the more likely you are to have extreme results. If you’re not aware of this principle, when you have small sample sizes, you may be misled by outliers. We’ll cover two examples of the law of small numbers in action and how to use your awareness of it to make better decisions.
