THREAD: 15 of the most useful razors and rules I've found.

Rules of thumb that simplify decisions.

Bezos' Razors:

• If unsure what action to take, let your 80-year-old self make it.

• If unsure who to work with, pick the person that has the best chances of breaking you out of a 3rd world prison.
Skinner's Law:

• If procrastinating on an item, you only have 2 options:

1. Make the pain of not doing it greater than the pain of doing it.

2. Make the pleasure of doing it greater than the pleasure of not doing it.
Luck Razor:

• If stuck with 2 equal options, pick the one that feels like it will produce the most luck later down the line.

I used this razor to go for drinks with a stranger rather than watch Netflix.

In hindsight, it was the highest ROI decision I've ever made.
Bragging Razor:

• If someone brags about their success or happiness, assume it’s half what they claim.

• If someone downplays their success or happiness, assume it’s double what they claim.

The map is not the terrain.
Hofstadter’s Law: 

• It always takes longer than you expect, even when you take into account Hofstadter’s Law.

Every project costs 2x as much and takes 3x as long - even when you factor this into your projections.
Elon's Law:

• If you have a project, combat Hofstader's Law by setting a ridiculously ambitious deadline.

Even if it takes 3x longer than the deadline, you're ahead of everyone else.

Elon Musk missing his super human deadlines is a feature rather than a bug.
Naval's Razors:

• If you have 2 choices to make and it's 50/50, take the path that’s more painful in the short term.

• If a task is worth less than your ambitious hourly rate - outsource it, automate it or delete it.

Munger's Law:

• Never allow yourself to have an opinion on a subject unless you can state the opposing argument better than the opposition can.

Steelman Arguments > Strawman Arguments
Hitchen's Razor:

• What can be asserted without evidence can be dismissed without evidence.
Newton's Flaming Laser Sword:

• If something can be settled by experiment or observation, then it is not worthy of debate.

UFC 1 >>> Decade long debates on the best martial arts
Joe Rogan's Razors:

• If unsure what action to take - ask what the hero in the movie would do.

• If you're intensely passionate about something and nobody around you is interested in it - assume the scale of the internet might help you find them.
Taleb's Surgeon:

• If presented with two seemingly equal candidates for a role, pick the one with the least amount of charisma.

The uncharismatic one has got there despite their lack of charisma.

The charismatic one has got there with the aid of their charisma.
Discomfort Razor:

• The more uncomfortable the activity, the more likely it will lead to growth.

• The more comfortable the activity, the more likely it will lead to stagnation.

1000 uncomfortable hours > 10,000 comfortable hours
Checkhov's Gun:

• When telling a story, if it's non-essential - don't include it.

"If you say in the 1st chapter that there is a rifle hanging on the wall, in the 2nd or 3rd chapter it absolutely must go off. If it's not going to be fired, it shouldn't be hanging there."
Occam's Razor:

• Simple assumptions are more likely to be correct than complex assumptions.

Avoid Occam's Duct Tape:

• Someone who approaches a problem with a ridiculously large number of assumptions.
Walt Disney's Rule:

• If struggling to think clearly about a subject, draw it out.

Here's Walt Disney's drawing he made in 1957 of the Media Empire he wanted to build.

It's iconic.
Schwarzeneggers' Rule:

• Never need to monetize your artistic pursuits. You won't have to sacrifice your inner joy and vision for a payday.

Arnold made millions from property and D2C bodybuilding guides so he never had to say yes to acting gigs he didn't like.

Recently, the @CNIL issued a decision regarding the GDPR compliance of an unknown French adtech company named "Vectaury". It may seem like small fry, but the decision has potential wide-ranging impacts for Google, the IAB framework, and today's adtech. It's thread time! 👇

It's all in French, but if you're up for it you can read:
• Their blog post (lacks the most interesting details):
https://t.co/PHkDcOT1hy
• Their high-level legal decision: https://t.co/hwpiEvjodt
• The full notification: https://t.co/QQB7rfynha

I've read it so you needn't!

Vectaury was collecting geolocation data in order to create profiles (eg. people who often go to this or that type of shop) so as to power ad targeting. They operate through embedded SDKs and ad bidding, making them invisible to users.

The @CNIL notes that profiling based off of geolocation presents particular risks since it reveals people's movements and habits. As risky, the processing requires consent — this will be the heart of their assessment.

Interesting point: they justify the decision in part because of how many people COULD be targeted in this way (rather than how many have — though they note that too). Because it's on a phone, and many have phones, it is considered large-scale processing no matter what.
