Hey friend š
Today we will discuss a mental model called The Sunk Costs Fallacy.
This is where we let our past mistakes weigh down on our future decisions.
The ācostsā of the pasts, impact the āinvestmentsā for the future.
Today is going to be fun!

The Sunk Costs Fallacy
š¤ What is it?
The Sunk Costs Fallacy is our tendency to stick with poor past decisions because we are too deeply invested in them.
We think of those past costs as investments.
And we donāt want to back away from those investments right before they start paying dividends.
Without realizing that those supposed āinvestmentsā are actually ācostsā that are dragging back our ability to make sound future investments.
š”Where does this model come from?
This model comes from accountancy, where the costs already borne for a business and cannot be recovered anymore are called sunk costs.
You know stuff like buying heavy machinery and equipment. Stuff like that.
But this concept applies to a wide array of fieldsā like business, finance and even personal relationships.
šÆHow Should We Tackle The Sunk Costs Fallacy?
There are 3 important steps to tackle Sunk Costs Fallacy:
Know Itās A Cost. Donāt live under the illusion that your past decisions were investments. Think of them as costs, and objectively evaluate if those costs add any value to you now or not.
Re-evaluate your Decision. Rethink about your decisions with an open mind. Nothing in life is set in stone. Be nimble, assess your decisions and change them if needed.
Know Your Stop Loss. Have some humility and accept some losses. Be ready to walk away from past mistakes. Be ready to change your own mind.
The ability to comfortably change your mind is at the heart of prudent decision-making.
Successful decision-makers donāt make one off great decisions, instead they follow a rational process and are always open to re-evaluate their decisions.
They iterate and evolve their process and over time become masters at the craft.
