Startups and Investing

A startup company is an anti-social amount of work on an emotional roller coaster with a likely ultimate disappointment. But, it might make millions of people happier.

Innovation density (per person, per hour, and per dollar invested) is greatest in early stage startup companies.

Being able to risk embarrassment enables one to attempt things that can yield large successes. Embarrassing outcomes are less likely than expected and come fast enough to try again. Large successes are almost certain for those who can risk embarrassment.

At the earliest stages of a startup company, the CEO’s main responsibility is selling. That is selling the product to customers and the stock to investors. It’s about the same for public companies.

Revenue is the best non-dilutive funding. Unless supporting early customers takes resources away from developing a later larger revenue stream. In that case, grants are the best non-dilutive funding.

In business, don’t invent what you can buy. Therefore, in B2B, make the boring things your customers need. You can sell it more than once. Don’t make whatever provides your customer their competitive advantage. You can only sell that once. In fact, zero times.

The investment portfolio with the best returns bets everything on the one asset that will have the most future growth. Diversification is a hedge against the uncertainty of which asset that is.

How to succeed in investing.
1. Compound.
2. Don't get wiped out.

Four ways to explain predictions
1. Trends
2. Cycles
3. Repetitions
4. Discontinuities

Investing requires predicting the future. Finding opportunities for good returns comes from the uncomfortable exercise of guessing at the unknowable. Extrapolating from trends masks profitable insights. Still, trend charts are stimulating, like a good story. That’s why the media loves trend charts.

Spending increases entropy.
Investing decreases entropy.

The phrase "supply-demand mismatch" in a market with elasticity is a misnomer for an undesired price. A famine results from a supply-demand mismatch. Wage rates do not.

Startup companies are the ones curing cancer, ending Alzheimer’s disease, creating crops to end hunger, and engineering microbes to slow climate change. Venture capital is philanthropy.

$1 donated to the Disease Foundation will help to relieve somebody's suffering in the near future. The same invested in the right startup will ensure that nobody in the farther future ever suffers the disease again. And give back $100.

VC investing is the most efficient philanthropy. To get funded, startups face intense competition to make things people want. They are held strictly accountable. Many fail. Nonprofits face light scrutiny. Unmeasurable goals let them declare every effort a success.

Charity is indulgence in self-esteem.

Science

To know the truth, learn something that might be true and try, seriously, to prove it false. Truth is confirmed to the extent of the effort that cannot prove it false.

Creativity supposes new ideas. Science attempts to prove them false.

A hypothesis is an idea that is intuitively true. A hypothesis becomes a theory after zealous, diligent testing fails to prove it false.

Does science discover things that engineering puts to practical use or does engineering figure out useful things that science then explains?

It is possible to be reasonable, rational, and wrong. It can be tempting, when right, to view a debating counterpart as unreasonable and irrational. The best debater admits when the other’s argument is reasonable and rational and explains why it is wrong.

Time is unidirectional. The accumulation of human knowledge tends to be. But it can be diminished. It has been in some earlier societies. The Nobel prize winners' book Why Nations Fail gives some examples.

Tokenization of concepts (words) and digitization (numbers) set humans apart from other animals. They enable error-free information transfer, which enables precision in a noisy world, which enables communication of complex concepts, which enables the modern world.

Two kinds of efficiency:
(a) Allocation of scarce resources (e.g. energy, time, money, attention) to uses in proportion to importance
(b) Allocation of scarce resources to uses in a waterfall from most towards least important

People tend to inaccurately estimate or even completely overlook event probabilities. As a result, in consideration of unpleasant but very improbable possibilities, people choose to incur, and policymakers impose, irrational costs for avoiding the possibility.

The notion that people evolved from monkeys insults monkeys. People and monkeys evolved from a common ancestor that was no more a monkey than it was a person.

We are all mutants. Everybody has some genes that are different from normal. Each of our unique combinations of mutations gives us a super ability in a certain situation.

We can culture human cells to save human lives. We can culture animal cells for meat to eat. Why not culture human cells to eat?

A human life begins somewhere between meiosis and college.

Germ line gene editing would no more increase human inequality than, for example, access to electricity does. The fallacy otherwise is premised on the implausible assumption that costs of the technology will remain high over the timescale of human generations. 

Various animal species have evolved to both discern and emit complex signals by touch, smell, and sound. Many species can discern complex electromagnetic signals (vision). Why have no animals evolved to *emit* complex electromagnetic signals?

Being aboard any modern commercial airplane is much safer than driving, even in the safest automobiles. A modern autonomous vehicle is safer than one driven by even the safest person.

When it was difficult to make ornate things such as frilly clothing, elaborate metal objects, and fancy fonts they became status symbols. Once technology made their production cheap, simplicity became fashionable.

Nomads have more leisure but farmers use land efficiently. Malthus underestimated technology. But perhaps the toil of farming at the cost of nomadic lands is a taste of his predicted doom.

Learning a subject, the more you know, the more you realize how much you don't know. Until a point where there is less and less you don't know. For learning everything, we are ever learning how much we don't know.

Mastering anything gives the confidence to fumble through something new. Fumbling is a fast way to learn. That’s why people who are great at one thing tend to be good at many. 

Understanding a complex subject requires learning multiple levels of recursive exceptions.

Explaining a complex subject clearly requires recursing to the right depth for the audience and accepting the discomfort of being inaccurate. Inaccuracy helps clarity.

Researching a complex subject requires supposing exceptions and demonstrating evidence that they are correct.

Social science has sides. Real science does not.

Many social science publications are untrustworthy, consisting of an inferred intuitive conclusion with statistics implying a cause without explaining (a) how the cause leads to the conclusion and (b) how other causes would not lead to the same conclusion.

Few things in nature come in discrete values. Most things worth knowing can only be accurately described as amounts, degrees, or probabilities.

Information transfer is most accurate when binary. Human nature innately understands this. 1-bit binary identity grouping minimizes effortful analysis.

A diagnostic test that always shows a positive result will be correct for 100% of positive cases. But it’s completely useless.

Precision is specificity. Accuracy is correctness.
Pi=3.1 is very accurate but not very imprecise.
Pi=3.1295606 is very precise but not very accurate.

The choice of base-10 for the decimal system is arbitrary, likely a result of people using fingers to calculate. Had they used hands instead, base-2 might have become the standard. It would have been easier to teach people how computers do math.

Logic: When a low probability event occurs, if it is momentous, we tend to overestimate the probability of its recurrence.
Reason: When a momentous event occurs, even if it is low probability, it is reasonable to reassess its probability.

Crossing a street mid-block is safer than crossing at an intersection.

A rigid 4-leg chair will always rock. Only 3-legged chairs are stable.

The Egyptians designed pyramids using papyrus. The Mayans used graph paper.

A rectangle is a Manhattan ellipse.

Mammals suck.

Logic and Reasoning

When somebody feels strongly about a controversial subject, they are probably overlooking a valid concern. Subjects are only controversial when there are valid concerns on both sides.

Strong opinions are often the result of oversimplifying something complex. Questioning them can be enlightening.

Usually, in the long run, whoever argues the evidence prevails over whomever argues the rules.

It is easier to think about what can be seen than what can’t. It is easier to think about what has happened than what might.

It is more comfortable to think about the past than the future. It is more useful to think about the future than the past.

Attributes of a particular instance are not evidence that a similar instance would be the same. They only show a single possibility.

Beware inferring a cause from a correlation. Four kinds of causes can make an AB correlation:
A causes B
B causes A
C causes A and B
random chance

When something looks wrong, figure out why it is that way before criticizing it.

It is lazy to criticize a person, meaningful to criticize their actions, and informative to criticize their ideas.

Most things worth knowing can be learned for free.

Teaching is like learning twice.
Writing is like reading twice. 

Merely learning is selfish. Learning to teach is neutral. Learning and using the knowledge to create is respectable. If the creation is useful to others, the learning was noble.

Trying to prove others wrong is an effective way to learn. Failure is confirmation. Success is education. Keeping it to oneself helps to maintain friendly relationships. Trying to prove oneself wrong is equally effective but recurses faster.

The discipline to ignore the interesting things people say make it easier to learn from observing what they do. Perhaps it could be called a mental mute button.

A right to compensation is often sold under the word "protection". This is comforting but incorrect. Insurance offers compensation for, not protection from, harm. Only in a superstitious mind is a right to compensation protection.

News reports seem more enlightening when presented in the form of an expert interview even though the time spent asking questions could have been used to deliver even more enlightenment. The most enlightening news sources don’t use interview format.

Citations seem profound when the name of the source is prefixed with the phrase “Nobel prize winner”. The prefix “a Harvard study” does the same to even mediocre research. This is the Halo Effect. The merit of an idea is independent of its source.

Nobel prize winners were most insightful before they were Nobel prize winners.

Compromising is inefficient. When there are multiple choices, and it’s not clear which is best, splitting the difference ensures a suboptimal outcome. Research and rational consideration will tend to yield the best result more often than a gut feel will, even if based on much experience.

If you choose not to choose, you have chosen somebody else's choice. 

When an unfortunate venture reaches a situation in which no hope remains for achieving its objective, striving onward has a net effect somewhere between wasteful and harmful to others. Sometimes quitting is most honorable.

To suffer for your principles is holy. To cause others to suffer for your principles is ass holy.

There are always two parties who can end a dispute.

If somebody is not trustworthy, at least they could have the courtesy to be predictable.

In a new relationship, the choices of restaurants, movies, etc is the union of the partners' preferences. In an old relationship it is the intersection.

Driving is dangerous. Some cars are safer than others. By choose which car to buy, one is putting a price on a human life.

For people, places, and things, interestingness gradually declines as familiarity grows. When, occasionally, something uninteresting becomes interesting, it usually happens suddenly.

It is difficult to change one’s personality. But an extended period of humiliation usually cures arrogance.

Practicing occasional public failure frees a person, mentally, to take large risks. Many great things can only be accomplished by taking large risks.

The word "percent" is a warning sign that what is being said is misleading.

The more interesting a statistic is, the more likely it is misleading.

Language

Authentic scientists and honest experts rarely speak in absolutes.

The words “need” and “should” lack meaning unless accompanied by an explanation of a benefit of fulfilling or consequence of failure to fulfill what is allegedly required.

Statements using words like “enough” or “too” without the word “to” or “for” are meaningless and beg critical questioning. For example, discussing whether 20 minutes is too long or not long enough is meaningless without specifying whether it is for baking a loaf of bread or a pizza.

Any “why” question has an infinite number of correct answers. “How” questions are nearly as broad. “Who”, “what”, “where”, and “when” are much more specific.

An ounce of inaccuracy saves a pound of explanation.

It is difficult to read while listening to somebody talk. In a business presentation, do not expect the audience to remember more than a few words written in the slides.

In the old days we were glad to have a good day with no problems. In modern times we are thrilled to have an awesome day with no issues.

Seem expert → be clear
utilize → use
provide → give
initiate → start
individual → person
prior to → before
obviously → 

The phrase “I’m sure” usually accompanies an assumption.

The phrase “with all due respect” usually precedes a phrase showing very little.

The phrase “last but not least” raises the question, “Which one was least?”

The phrase “split the baby”, which refers to the bible story of King Solomon, means destroying something two people want but can’t share. The phrase is often mistakenly used to describe compromising by “splitting the difference”.

What’s the past tense of the verb “can”?

The actors performance was moving, an effect that was effectively effected by his affect and affected me deeply.

Of common written languages, Korean is the most logical. Syllables are atomic and logographic like Chinese but phonemes are alphabetic like English such that learning pronunciation is simple.

Any analogy, extended far enough, falls apart. It is clearer to describe subjects directly, beginning with any prior knowledge needed to enable comprehension.

Law

In the US, statutes are laws from legislation by Congress. Regulations are made by the executive branch. Regulations are meant to be no more than rules for implementing the statutes. Chief executives (Presidents) of both major parties habitually exceed their constitutional authority.

Stare decisis is intended to maximize people’s certainty about the law. It is the legal principle that, where laws are ambiguous, they should be clarified (by courts or Congress) in whatever way most reasonable people would have supposed the law to be.
