50 Ideas That Changed My Life — David Perell

Inversion: Avoiding stupidity is easier than trying to be brilliant. Instead of asking, “How can I help my company?” you should ask, “What’s hurting my company the most and how can I avoid it?” Identify obvious failure points, and steer clear of them.

Theory of Constraints: A system is only as strong as its weakest point. Focus on the bottleneck. Counterintuitively, if you break down the entire system and optimize each component individually, you’ll lower the effectiveness of the system. Optimize the entire system instead.

Preference Falsification: People lie about their true opinions and conform to socially acceptable preferences instead. In private they’ll say one thing. In public, they’ll say another. 

Mimetic Theory of Desire: Humans are like sheep. We don’t know what we want, so we imitate each other. Instead of creating our own desires, we desire the same things as other people. The entire advertising industry is built on this idea. 

Talent vs. Genius: Society is good at training talent but terrible at cultivating genius. Talented people are good at hitting targets others can’t hit, but geniuses find targets others can’t see. They are opposite modes of excellence. Talent is predictable, genius is unpredictable.

Competition is for Losers: Avoid competition. Stop copying what everybody else is doing. If you work at a for-profit company, work on problems that would not otherwise be solved. If you’re at a non-profit, fix unpopular problems. Life is easier when you don’t compete. (Hint: don’t start another bottled water company). 

Russell Conjugation: Journalists often change the meaning of a sentence by replacing one word with a synonym that implies a different meaning. For example, the same person can support an estate tax but oppose a death tax — even though they are the same thing.

Opportunity Cost: By reading this tweet, you are choosing not to read something else. Everything we do is like this. Doing one thing requires giving up another. Whenever you explicitly choose to do one thing, you implicitly choose not to do another thing. 

Planck’s Principle: Science doesn’t progress because people change their views. Rather, each new generation of scientists has different views. As old generations pass away, new ideas are accepted and the scientific consensus changes.

Bike-Shed Effect: A group of people working on a project will fight over the most trivial ideas. They’ll ignore what’s complicated. They’ll focus too much on easy-to-understand ideas at the expense of important, but hard to talk about ideas. For example, instead of approving plans for a complicated spaceship, the team would argue over the color of the astronaut’s uniforms.

Table Selection: This idea comes from poker, where you’re advised to choose your opponents carefully. That means you shouldn’t compete against the best people. You don’t need to get good at doing difficult things if you get good at avoiding difficult things. If you want to win, pick an easy table and nail your execution.

Goodhart’s Law: When a measure becomes a target, it ceases to be a good measure. One hospital took too long to admit patients so a penalty was given for 4+ hour wait times. In response, ambulance drivers were asked to slow down so they could shorten wait times. 

Gall’s Law: A complex system that works is invariably found to have evolved from a simple system that worked. A complex system designed from scratch never works and cannot be patched up to make it work. You have to start over with a working simple system.

Hock Principle: Simple, clear purpose and principles give rise to complex and intelligent behavior. Complex rules and regulations give rise to simple and stupid behavior.

The Second Law of Thermodynamics: The world tends towards disorder. That’s why your room becomes messier and messier over time. It’s also why an engine converts only ~35% of its energy into useful work. Time moves towards increasing one direction: increasing entropy. 

The Paradox of Specificity: Focus isn’t as constraining as it seems. In the age of the Internet, when everybody has Google search and personalized social media feeds, differentiation is free marketing. The more specific your goal, the more opportunities you’ll create for yourself. Narrowing your aperture can expand your horizons.

Occam’s Razor: If there are multiple explanations for why something happened and they are equally persuasive, assume the simplest one is true. In the search for truth, remove unnecessary assumptions. Trust the lowest-complexity answer. 

Hormesis: A low dose of something can have the opposite effect of a high dose. A little bit of stress wakes you up, but a lot of stress is bad for you. Lifting weights for 30 minutes per day is good for you, but lifting weights for 6 hours per day will destroy your muscles. Stress yourself, but not too much.

Horseshoe Theory: Extreme opposites tend to look the same. For example, a far-right movement and a far-left movement can be equally violent or desire a similar outcome. People on both sides are more similar to each other than they are to people in the center. 

Creativity Begins at the Edge: Change starts away from the spotlight. Then, it moves towards the center. That’s why the most interesting ideas at a conference never come from the main stage. They come from the hallways and the bar after sunset

The Paradox of Consensus: Under ancient Jewish law, if a suspect was found guilty by every judge, they were deemed innocent. Too much agreement implied a systemic error in the judicial process. Unanimous agreement sometimes leads to bad decisions. 

Convexity: If you want to be lucky, look for opportunities with big upsides and low downsides. In addition to increased optionality, your errors will benefit you more than they harm you. Convex payoffs let you tinker your way to success and innovation. 

The Go-For-It Window: Large gaps between accelerating technologies and stagnating social norms create lucrative new business opportunities. But they are only available for a short time when people can capitalize on the difference between the real and perceived state of the world. For example, 2007 was the perfect time to launch the iPhone, but Google Glasses launched too early.

Via Negativa: When we have a problem, our natural instinct is to add a new habit or purchase a fix. But sometimes, you can improve your life by taking things away. For example, the foods you avoid are more important than the foods you eat.
