Hardy names three cognitive biases, all rooted in loss aversion, that keep people trapped in the 80%. Sunk cost bias makes you keep reinvesting in something because you've already put so much in, like finishing a movie you dislike. The endowment effect makes you overvalue things simply because they're yours, which is why it's easier to advise others than yourself. The consistency principle, from Robert Cialdini's Influence, makes you keep acting like your past self to appear consistent to others. The antidote is psychological flexibility and being consistent with your future self instead.
Origin
Hardy draws on standard behavioral psychology and Robert Cialdini's Influence, applying these biases to the challenge of releasing the 80% in 10x Is Easier Than 2x.
Core principles
- 01Sunk cost bias keeps you reinvesting in something just because you've already invested in it.
- 02The endowment effect makes you overvalue what is yours, so you can't judge it objectively.
- 03The consistency principle makes you keep acting like your past self to appear consistent to others.
- 04These biases are the emotional glue holding you in the secure 80%.
- 05Be consistent with your future self, not your past self.
How to run it
- 1
Spot sunk cost bias
Notice when you keep doing something only because you've already invested time, money, or effort in it.
Pro tip If the juice is no longer worth the squeeze, past investment is irrelevant; let it go.
- 2
Counter the endowment effect
Recognize you overvalue what is yours, then give yourself the objective advice you'd give a friend.
Pro tip Ask what you'd tell someone else in exactly your situation.

Break the consistency principle
Accept being seen as inconsistent with your past self so you can align with a radically different future self.
Pro tip Most people don't really care and won't ask the awkward questions you fear.
Watch out The consistency principle can trap you in an old identity because you fear what old friends will think.
In the wild
Hardy notes people walk around with super old phones because the endowment effect makes parting with their own item feel like a big deal, even when an upgrade is clearly better.

Common mistakes
Confusing appearing consistent with being right
Wanting to look consistent to others keeps people locked in an outdated identity. A big future requires being inconsistent with your past self, which demands psychological flexibility.
Is it for you?
Best for
Anyone trying to release habits, relationships, or commitments that no longer serve their future.
