Lindy Effect 101

With Bitcoin's return to the spotlight, debates on its long-term viability are raging. Its proponents contend @nntaleb's Lindy Effect says the technology is here to stay.

But what is the "Lindy Effect" and how does it work?

Here's Lindy Effect 101!

👇👇👇

1/ First, a few definitions.

The Lindy Effect is a theory that the future life expectancy of specific non-perishable items, like a technology or idea, is proportional to their age.

Put simply, the longer it has already lasted, the higher the likelihood it will continue to last.

2/ The term "Lindy effect" is a reference to Lindy's, a New York deli frequented by comedians in the 1960s.

While author Albert Goldman used the term "Lindy's Law" in a 1964 article, it was mathematician Benoit Mandlebrot who moved the dialogue towards the current definition.

3/ In his book, entitled The Fractal Geometry of Nature, Mandlebrot commented that the more stage appearances a Lindy's comedian made, the more future appearances he could be predicted to make.

The longer he lasted, the longer he would continue to last.

4/ @nntaleb built upon Mandelbrot's work, formally coining the term "Lindy Effect" in his book, Antifragile.

He noted the Lindy Effect with books - the longer a book has been in print, the longer it is likely to survive.

With no natural upper bound, power laws come into play.

To outperform, you need serious problem-solving skills.

Fortunately, these skills can be learned.

THREAD: A simple, powerful mental model for thinking clearly and solving complex problems:

When solving problems, the human mind is wired to think in linear, logical, forward terms.

But as the problems get increasingly complex, this forward, logical process often fails.

Enter our simple, powerful mental model: inversion.

What is inversion?

Inversion is a mental model and thinking tool used by some of the world’s greatest thinkers and problem solvers.

Simply put, it says that when problems become challenging to solve forwards, they may be more readily solved backwards.

Inversion as a general thinking tool has been around for millennia.

Stoic philosophers had premeditatio malorum - “the pre-meditation of evils” - an exercise in which they would imagine the worst case scenario ahead of time.

It allowed them to make plans to avoid this outcome.

The formal mental model was popularized by German mathematician Carl Jacobi in the mid-1800s.

When faced with difficult problems (which happened frequently in his field of elliptic functions!), he had a strategy: “Man muss immer umkehren.”

Translation: “Invert, always invert.”

The @JeffBezos Regret Minimization Framework is a simple yet powerful mental model for making important decisions and unlocking growth in your career, startup, business, relationships, or life.

A short thread on how it works and how it can change your life...

Jeffrey Preston Bezos is an American entrepreneur and technologist.

He is most well known as the founder and CEO (soon-to-be executive chairman) of Amazon and the founder of Blue Origin.

A legendary figure today, he may have remained anonymous if not for one key decision.

In 1994, at age 30, Jeff Bezos was a star at D.E. Shaw, a successful quant-focused hedge fund.

He was on a lucrative path.

But he had become obsessed with a new thing called "the internet" and its power to change the world.

He had a vision of participating in that future.

Bezos had a decision to make.

Stay at D.E. Shaw - with a high likelihood of wealth creation and "success" - or leave and pursue his speculative, crazy new idea.

He developed a framework for making this (and many future) decisions:

The Regret Minimization Framework.

The Regret Minimization Framework is simple.

The goal is to minimize the number of regrets in life.

So when faced with a difficult decision:
(1) Project yourself forward into the future.
(2) Look back on the decision.
(3) Ask "Will I regret not doing this?"
(4) Act accordingly.

5 simple principles to accelerate your career:

Principle: Follow Your Curiosity

Humans are born with astonishing curiosity.

But somewhere along the way, we're told to stop asking questions.

Push back.

Learn to follow your curiosity—trust it.

For the curious mind, anything is possible.

Fortune favors the curious.

Principle: Operate in Your Zone of Genius

Your Zone of Genius is where your interests, passions and skills align.

Operating in your Zone of Genius means playing games you are uniquely well-suited to win.

It means you can stop playing *their* games and start playing *yours*.

Principle: Adopt a Positive Sum Mentality

Want to get ahead in life?

Start genuinely rooting for others to succeed.

When one of us wins, we all win—winning spreads.

If you adopt that mentality, you’ll become a magnet for the highest quality people.

Principle: Speak Up

Closed mouths don’t get fed.

A little push goes a long way.

Don't sit back and wait for good things to happen.

If you want something—and you’ve put in the work for it—ask for it.

Worst case: you’re told no and nothing has changed.

Best case: it’s yours.

10 fascinating traits of highly-successful people:

1) Enjoy Being Wrong: The most successful people legitimately enjoy being wrong. They’ve learned to embrace new information that forces you to change your viewpoint—these "software updates" improve upon the old.

2) Work in Sprints: Parkinson's Law says that work expands to fill the time available for its completion. Winners typically work like lions instead—sprint, rest, repeat.

3) Antifragile: Life is chaotic. The best aren't broken by the chaos—they build structure to benefit from it.

4) Paranoia: Highly-successful people share a surprising fear that all of the success is suddenly going to disappear. It creates a drive for continued growth.

5) Self-Awareness: The most successful people are hyper self-aware. They know their unique edge (and their weaknesses).

6) Compartmentalization: An uncanny ability to compartmentalize. They turn off outside stressors and focus exclusively on the task at hand.

7) Focus on Questions, Not Answers: They ask great questions. It allows them to aggregate insights more effectively.

8) Expert Advice Filters: Winners have learned how to filter and selectively implement advice—take the signal, skip the noise.

9) Impatient Long-Term Thinkers: Long-term thinking plus short-term impatience for action is the recipe for success.
