A “razor” is a rule of thumb that simplifies decision-making.
All geniuses of the world use razors constantly.
The 9 most powerful razors I’ve found:
(explained in two minutes)
1. Sagan’s Standard
Extraordinary claims demand evidence scaled to their improbability.
When confronted with claims like "crystals cure cancer" the burden of proof lies not in dismissing them outright, but in requiring replicable data from controlled studies.
2. Grice’s Razor
Interpret statements through the lens of implied intent rather than literal meaning.
This razor recognizes human communication as a dance of subtext, where context and shared assumptions outweigh dictionary definitions.
3. Newton’s Flaming Laser Sword
Focusing on untestable ideas like multiverses wastes mental energy. Instead, prioritize testable questions, like which renewable energy storage solutions are most efficient
It confines productive discourse to the realm of falsifiable hypotheses
4. Occam’s Broom
The selective omission of inconvenient data often disguises itself as elegant simplicity.
Stemming from "Occam's Razor", this warns against theories too neatly aligned with their proponents’ interests.
5. Clark’s Law
Catastrophic outcomes more frequently stem from compounded incompetence than calculated malice.
The 2008 crash wasn't from bond traders’ villainy, but from layered institutional failures.
Systemic analysis > villain narratives
7. Wittgenstein’s Ruler
Measurement tools reveal as much about their users as their subjects.
The statistic often says more about how questions were framed than actual public sentiment. True calibration requires interrogating both instrument and intent.
8. Stink’s Razor
Persistent rejection of overwhelming evidence constitutes ethical failure, not intellectual disagreement.
Certain denialism persists not through ignorance of science, but through active resistance to paradigm shifts that threaten existing power structures.
9. Hume’s Guillotine
“No ‘ought’ can be derived from an ‘is.’”
David Hume’s epistemological divide argues moral imperatives cannot logically flow from factual observations.
That's a wrap!

A “razor” is a rule of thumb that simplifies decision-making.
All geniuses of the world use razors constantly.
The 5 most powerful razors I’ve found:
(explained in 60 seconds)
1. Chesterton’s Fence
“Do not remove a fence until you know why it was erected.”
G.K. Chesterton warned against dismantling systems without understanding their original purpose.
A company abolishing “outdated” weekly meetings might later discover they prevented departmental silos.
This principle advocates humility: assume historical solutions addressed real problems, even if their rationale is no longer obvious.
2. Brandolini’s Law
“The energy required to refute nonsense exceeds that needed to produce it.”
Misinformation spreads exponentially because debunking requires evidence, while lies demand only creativity. This asymmetry explains why bad actors weaponize algorithms optimized for engagement over truth.

The Status Quo Principle
People tend to maintain their current behavior unless there’s either decreased friction or increased motivation. To change habits effectively, focus on:
•Reducing obstacles to desired behaviors
•Increasing motivation through immediate rewards
The Environment-Behavior Connection
Behavior is a direct function of both personal factors and environmental conditions. To create lasting change:
•Modify your environment first, rather than relying on willpower
•Remove triggers that lead to unwanted behaviors
