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!

👇👇👇

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.”

Survivorship Bias 101

History is written by the victors. But if we exclusively focus on these successes, we allow survivorship bias to distort our understanding of the world.

But what is "survivorship bias" and how does it work?

Here's Survivorship Bias 101!

👇👇👇

1/ First, a few definitions.

Survivorship bias is the logical error of concentrating on survivors (successes) and ignoring casualties (failures).

When we do so, we miss the true "base rates" of survival (the actual probability of success) and arrive at flawed conclusions.

2/ When we completely ignore failures, we lose our ability to correctly identify the differences between successes and failures.

Put simply, exclusively focusing on successes may actually inhibit our ability to identify (and replicate) the actions that led to such success.

3/ Cicero wrote on the topic over 2,000 years ago.

An atheist named Diagoras is shown portraits of people who prayed and were saved from death at sea as proof of God's existence.

Diagoras replies, "I see those who were saved, but where are those painted who were shipwrecked?"

4/ Cicero cuts right to the point - we cannot conclude that prayer led to being saved from the sea if we ignore those who prayed and then drowned.

Survivorship bias can lead to a deeply-flawed understanding of cause-and-effect relationships.

Let's look at some examples.

These paradoxes will change your life:

The Brakes Paradox

What allows a Formula 1 driver to fly around the track?

It's not the engine, the tires, or the suspension.

It's the brakes.

Strong, reliable brakes unlock the driver.

Build brakes into your life that allow you to accelerate and hit turns without fear.

The Advice Paradox

Taking more advice leaves you less well-equipped.

Most advice sucks.

It's well-intentioned, but it's dangerous to use someone else's map of reality to navigate yours.

Winners learn to filter and selectively implement advice—take the signal, skip the noise.

The Opportunity Paradox

Take on less, accomplish more.

Success doesn’t come from taking on every opportunity.

It comes from deploying energy on the opportunities that matter—the 10x opportunities.

Time and energy are finite.

Say yes to what matters & no to everything else.

The Persuasion Paradox

Have you noticed that argumentative people rarely persuade anyone of anything?

Persuasive people don’t argue—they observe, listen, and ask questions.

Argue less, persuade more.

Persuasion is an art that requires a paintbrush, not a sledgehammer.

The Icarus Paradox offers a critical lesson on business, investing, and life.

Here’s a simple breakdown:

The story of Icarus is a famous tale from Greek mythology.

Icarus is the son of a craftsman—Daedalus.

To help the pair escape from Crete, Daedalus uses feathers and wax to create two sets of wings.

Prior to the attempt, Daedalus warns his son to avoid complacency and hubris.

Daedalus instructs Icarus to avoid flying too low or too high—cautioning that the sea's moisture or the sun's heat could cause the wings to malfunction.

But Icarus becomes amazed by his flight and soars away.

The sun melts the wax on his wings and Icarus falls to his death.

The tale of Icarus offers a poignant lesson:

Avoid complacency and hubris at all times.

What makes you successful initially may eventually lead to your downfall.

This is often referred to as "The Icarus Paradox”—it shows up constantly in business, investing, and life:

In business, how many incumbents have we seen achieve success with one product, only to be disrupted when the market shifts under their feet?

Overconfidence and success blinds incumbents to the coming wave of disruption.

60+ companies from the 1966 Fortune 100 no longer exist!

Think crypto is confusing?

You're right.

Let's make it easier.

Here's Crypto Terminology 101: 🧵

Altcoin:

Any coin that's not #Bitcoin

Ether (#ETH) is the second most popular coin overall and the most well-known Altcoin.

Ether is the native cryptocurrency on the Ethereum blockchain.

There are thousands of other altcoins, but for now, this is the one to know.

Bitcoin: (#BTC)

The first decentralized digital currency.

Launched in 2009 by an unknown person or organization known only as "Satoshi Nakamoto."

It is the most famous, and most valuable cryptocurrency.

Blockchain:

The core tech behind Bitcoin and most other cryptocurrencies.

An open, distributed, general ledger where transactions are organized into blocks which are then connected using cryptography.

Coin:

A store of digital value that lives on a blockchain.

Some blockchains, such as Bitcoin, use the same name for both the network and the coin.

Stable coins are another type of cryptocurrency which are backed by fiat currency (e.g the US dollar) or commodities such as Gold.

[1/13] It may be initially confusing to fully grasp how deposits and withdrawals from L1 to @optimismPBC are actually implemented, and it helps to see the on-chain action of what is happening behind the scenes.

[2/13] Initial setup (simplified): on L1 we have SyntheticBridgeToOptimism from Synthetic and OVM_L1CrossDomainManager from Optimism contracts. On L2 we have SynthetixBridgeToBase and OVM_L2_CrossDomainManager contracts.

[3/13] Additionally we have Sequencer (L2 mining node) that verifies all L2 transactions and submits them in batches to L1 for future reference and Relayer that is responsible for relaying messages from L2 —> L1

[4/13] Step 1 - Alice wants to deposit $SNX to L2. To do that she calls initiateDeposit() method on the L1 SyntheticBridgeToOptimism which takes her $SNX, puts it in the escrow and calls OVM_L1CrossDomainManager sendMessage() method.

[5/13] The CrossDomainManager puts this request to CanonicalTransactionChain (this is an “official” and “unmutable” list of all L2 transactions on L1). As a consequence the Sequencer (L2 mining node) will need to execute this transaction on L2.
