"Average" 🤔
Generally speaking, there's nothing average about the word “average”.
Born in a shipwreck… Here’s how it happened.
Picture a ferocious storm.
The crew throws cargo overboard to survive it.
Someone has to pick up the tab.
It can't fall on the unlucky merchant whose barrels went over.
Enter… General Average.
It’s shared proportionally by everyone financially tied to the voyage.
Shipowner, cargo interests, freight. All in.
The maths: total loss divided by total value at risk.
Merchants did this for centuries before the word escaped.
By the 18th century, "average" meant any proportional or middle value.
It traces back to the Rhodian Sea Law, 800 BC.
Codified into the York-Antwerp Rules.
Still used globally.
Still updated.
🫡 Shout out to the average adjusters… Shipping's unsung mathematicians.
By the law of averages, I’ve missed some important details.
What are they? Better to be Particular than General about it!
Fun Facts
⚓️ The word is Arabic. "Average" comes from the Arabic "awariya," meaning damaged goods. It travelled through Italian "avaria" and Old French "avarie" before landing in English. So every time someone says "average" they're using a word with three Mediterranean trade route stops embedded in it.
⚓️ Statisticians stole from shipping, not the other way around . Maritime General Average had been operating for around 2,500 years before mathematicians formalised "mean," "median," and "mode" in the 17th century. The trade was doing the maths long before anyone gave it a name.

There are fewer than 100 qualified average adjusters in the world. The Association of Average Adjusters has been around since 1869. Becoming one takes years of exams covering admiralty law, marine insurance, and maritime accounting. They're paid handsomely when something the size of the Ever Given goes wrong, and rightly so.
