The First-Principles Thinking Behind My Biggest Decisions
Why does capital flow where it does? A founder explains first principles, SPACs, SpaceX's IPO fees, network effects, and why independent thinking matters now.
Purpose of Self-Examination
The author argues that individuals should test their own views against the truth. Personal perspectives can reflect biases or insecurities rather than an accurate picture of the world.
The author applies this principle to a series of past decisions: founding Social Capital, advocating for Bitcoin and SPACs, and now building E15 and hosting a podcast. The author states that the common thread is the allocation of capital. The author also states that fixing mistakes from the past is a precondition for E15's chance of success. This is described as a minimum personal standard and a moral obligation to investors and colleagues.
Five Forms of Capital
The author states that capital takes several forms, and that each form is allocated in the same way:
| Form of capital | Description |
|---|---|
| Reputational capital | Signaling that one priority is more important than another, and starting a preference cascade so that others reach a similar conclusion through their own reasoning |
| Social capital | Influencing people's views on one option versus another |
| Time | Deciding where one spends one's time |
| Human capital | Influencing the people around oneself to work on specific problems |
| Financial capital | Directing money to specific activities |
The author argues that the more capital is directed toward a thing, the more that thing matters. As a result, it has a greater chance of becoming part of the future structure of society.
Capital Should Flow to Builders
Historical Origin
The author traces the term "venture capital" to "adventure capital." Wealthy British and Dutch merchants financed the exploration of new territories, including voyages to the United States and to the Cape of Good Hope and India. These investors sought adventure and directed surplus capital that had no productive use in traditional local opportunities.
Growth of Intermediation
As societies evolve, more builders emerge, and GDP increases, the financial structures between money and builders become more complex. The author contrasts the 1600s, when a single simple instrument connected the money and the adventurer, with the present, when many channels connect builders to sources of capital.
The author argues that intermediaries in this layered system can take more than they should. The author states that systems must be kept transparent so that the traditional system remains honest. Without this, intermediaries capture a disproportionate share of value that should go to builders.
Case Examples
SPACs. The author states that SPACs were designed to move money to builders more efficiently. At the time, the traditional IPO process was constrained. There was only one route to going public, a small number of banks controlled it, and companies had to wait in line. The author describes the institutions involved as possibly inefficient and states that the author's own incentives were not fully aligned with the ultimate owners of SPAC instruments. The author says this inefficiency is one that the author has tried to correct in the next iteration.
SpaceX IPO. The author states that Elon Musk was the only figure able to substantially reduce the economics captured by intermediary banks. The author cites the following comparison of the share of the IPO paid out on a per-share basis to intermediaries:
- Typical fee: 4%
- SpaceX IPO: 0.7% (7/10 of 1%)
The author states that this difference represents more money in Musk's hands. Musk has publicly stated that the scale of capital now available to him for making the species multi-planetary is meaningfully larger.
Purpose of IPOs
The author states that many people view IPOs mainly as a way to pay employees. The author states that this is a much smaller part of their function. The primary purpose is to finance 10, 15, or 20 years of building something important.
Role of SPACs Today
The author states that SPACs finance some of the most important but distant ideas on the risk curve. The author describes this as a positive development. The author does not argue that SPACs should make up most of capital market activity. The author argues that they have a place, because they help a more diverse and aggressive group of builders obtain the capital needed to push the boundaries of society.
Probability and Return Distribution
The author presents the following probability estimates for company valuation outcomes:
| Valuation range | Stated probability |
|---|---|
| Between 10 billion | 8% |
| Between 99 billion | 13% |
| Reaching $1 trillion | 31% |
From these estimates, the author describes two possible investment strategies:
- Wait until a company exceeds $100 billion in value, then buy a large position.
- Build a portfolio with many companies in the single-digit billion range and a moderate number in the tens of billions. Then invest 60% to 70% of the portfolio as soon as each company passes $100 billion.
The author states that the probability of reaching higher valuations increases as companies grow, rather than decreasing. The author attributes this to two properties of technology:
- Network effects, which are embedded in product loops, sales loops, feature cycles, and pricing.
- Compounding, which the author describes as the most powerful compounding mechanism available, stronger than interest.
The author states that society poorly understands these principles.
Independent Thinking
The author argues that independent thinking is the most important skill because people tend to share their views with a bias. The author includes himself in this statement. The author states that some of his own views reflect his biases, though not all of the time, and that everyone shares this tendency.
Changes in the Information Environment
The author states that decades ago, people could read a newspaper or watch a cable news channel and receive relatively factual news. The author states that this is no longer the case. Because media has become less reliable, individuals must do more of their own analysis.
The author expects the information environment to include more pundits, more opinions, more social media, and more citizen journalism. The author also expects tools that help people identify the truth.
AI Tools for Evaluating Information
The author states that the choice of tools matters. The author describes Grok as a tool that makes a strong effort to seek the truth. The author states that some other tools have shown less predictable behavior.
The author describes two methods:
- Direct query. When the author reads something, often on X, the author asks Grok, "What is the truth here?"
- Debate agent. The author uses an agent whose function is to argue each side of a topic. The author provides the full article to this agent. The agent argues both sides back and forth, then presents each side and a nuanced assessment.
The author states that this process is useful.
Conclusion
The author states that thinking from first principles benefits people at this point in time. The author acknowledges that this requires effort and that daily obligations, such as work, saving money, and raising a family, make it difficult to prioritize.
The author argues that the need is greater now because distractions are unlimited and downstream effects are large. The author compares independent thinking to maintaining physical health, such as eating well and sleeping enough. The author describes it as the most important way to optimize the mind. The author's recommended method is to provide the mind with clean inputs and allow it to do the work. The author states that this process produces good conclusions.
The author concludes that independence is the most important quality in a world shaped by bias.
Honesty and the Through-Line of Past Decisions
The speaker stresses honesty about one's own biases and seeks a common thread through his career choices, including his commitment to fixing past mistakes while building E15.
- He wants to keep himself honest about the truth and recognize when his worldview reflects biases or insecurities.
- He traces a through-line across Facebook, Social Capital, advocacy for Bitcoin and SPACs, starting E15, and a podcast.
- He considers building E15 a moral obligation to his investors and coworkers and wants to learn his past lessons properly.
Five Types of Capital
The speaker defines five kinds of capital that can be allocated: reputational, social, time, human, and financial. Directing capital shapes which ideas become part of society's future.
- Reputational capital means signaling that A is more important than B and triggering a preference cascade.
- Social capital means influencing people about A versus B.
- Allocation of time asks where one spends time; human capital asks how to influence people to work on certain problems.
- Financial capital is where money is put to work; the more capital directed to something, the more it matters.
Capital Should Flow to Builders
Venture capital traces back to 'adventure capital' financing explorers. As societies grow, financial intermediaries multiply and can take a disproportionate share that should go to builders.
- The term venture capital comes from adventure capital, funded by British and Dutch businesspeople exploring new territories.
- Voyages to the US, the Cape of Good Hope, and India were financed by adventure-seeking investors.
- In the 1600s there was a single simple instrument between money and adventurers; today many channels exist between builders and capital.
- Intermediaries can take more than they should, so systems must keep the traditional financial system honest.
SPACs, SpaceX IPO, and Cutting Intermediaries
The speaker uses SPACs and the SpaceX IPO as examples of capital reaching builders by cutting intermediary bank fees. He says the traditional IPO process had become sclerotic and inefficient.
- In the SpaceX IPO, the underwriting fee was about 0.7% instead of the typical 4%, which the speaker says increases money in Elon Musk's hands.
- IPOs fund the next 10 to 20 years of building, not just paying off employees.
- The traditional IPO route had only one way to go public and a handful of banks, requiring companies to wait in line.
- SPACs let companies put large amounts of capital on their balance sheets, though incentives were not aligned with the ultimate owners of the instruments.
Valuation Probabilities and Technology Compounding
The speaker presents probability estimates of company valuation growth and argues that technology's network effects and compounding make later-stage bets more attractive.
- He cites an 8% probability a company reaches a 1 to 10 billion dollar valuation, 13% for 11 to 99 billion, and 31% for reaching a trillion.
- He suggests waiting until a company passes 100 billion and then investing heavily, with 60 to 70% of a portfolio in that company.
- Technology has network effects and compounding embedded in product loops, sales loops, feature cycles, and pricing.
- He claims technology is a better compounding mechanism than interest.
Independent Thinking and Truth-Seeking Tools
The speaker argues that independent thinking matters more than ever because everyone has biases, media has become less trustworthy, and AI tools can help find truth.
- Everyone, including the speaker, has a bias to share their point of view, which can come from biases.
- Decades ago, newspapers and TV news were relatively factual, but the media is now seen as disreputable and untrustworthy.
- Future information will include more pundits, social media, and citizen journalism, plus tools that help find truth.
- He uses Grok to ask what the truth is and an agent that takes an article and argues either side to reveal a nuanced truth.
Conclusion: A Responsibility to Think Independently
The speaker urges listeners to adopt first-principles thinking as a responsibility, comparing it to healthy habits, and to give their minds clean inputs.
- First-principles thinking is exhausting but increasingly important because distractions are infinite and downstream impacts are large.
- Thinking independently is compared to eating well and getting enough sleep.
- The speaker recommends giving the mind clean inputs and allowing it to do the work to reach good conclusions.
- Being independent is described as the most important thing in a very biased world.
