One thought I keep coming back to is the immense consequences of how our units of length, weight and volume were defined. Products are often sold with round numbers (1 liter, 0.5 liter, 1 kg, etc). If you could go back in time and fiddle with e.g. the definition of a pint, you'd see that reducing its volume would lead to people drinking less, until it's so small that people just order two pints.

In Taiwan the standard way to drink beer is to get it in large bottles, but shared with a small glass per person. Easy to not drink much that way, and promotes the social “let me fill your glass” behavior. (making it harder to not drink much)
