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) Image
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. Image
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. Image
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 Image
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.

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) Image
Image
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.Image
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.Image

Did you know that saying "thank you" can physically restructure your brain?

Scientists discovered that 2 minutes of gratitude practice impacts your brain more than 1 hour of therapy.

The neuroscience behind this is mind-blowing... 🧵 Image
Inside your brain, gratitude activates multiple regions simultaneously:

• Prefrontal cortex (your moral compass)
• Ventral tegmental area (reward center)
• Hypothalamus (emotional regulation)

These areas work together to create lasting change... Image
Research shows something incredible: consistent gratitude practice increases gray matter volume in the right inferior temporal gyrus.

In English: gratitude literally grows your brain stronger in areas that make you more emotionally intelligent. Image

8 Principles About How The Human Mind Works:

(so you can master yourself for a better tomorrow) Image
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

The most fascinating thing about being human:

Those feelings we can't put into words;
what's lost in translation from thoughts to words.

That's the invisible threads connecting all our experiences, yet we struggle to name them.

Here are 12 concepts that finally explain them: Image
Novalunosis — The state of relaxation and wonderment while gazing upon the stars at night.
Wundervei — The deep introspection experienced in moments of isolated silence during a solo nature walk.

Relatable?

Here's why your brain "shuts off" when you see your crush or have an important test:

(thread) Image
1/ The test

The problem with the test: you perceive it as a threat.

Not because something's wrong with you. It's just how we're wired.

It's a threat because: in our evolutionary past, social standing directly impacted survival and reproduction chances.
Today’s academic tests trigger similar threat responses because they can determine:

• Social status
• Access to resources
• Group acceptance or rejection
• Reproductive opportunities through career prospects

23 Emotions people feel, but can't explain:

1/ Occhiolism: The awareness of the smallness of your perspective. Image
