It is impossible for a man to learn what he thinks he already knows.

Epictetus · Tuned to you

Mental model

Ask what would have to be true for the other side to be right.

A habit that turns arguments into information — you either find the crux of the disagreement, or you find your own error early.

The Long View — Disagreement, done well

Forecast

Within a decade, most knowledge work will be reviewing, not producing.

If generation gets cheap, judgment gets scarce — the argument that careers will reward taste over throughput.

Interview · 58m

Signal & Noise — The judgment economy

Opinion

Taste is the compounding asset — skills depreciate, judgment doesn’t.

Why one investor hires for what people notice, not what they know: knowledge dates quickly, discernment keeps paying.

Listen to the wisdom that makes us human

The average of everything is the wisdom of no one.

Ask a model for advice and you get everything ever said, blended smooth — fluent, sterile, and belonging to nobody. Perdisco is built on the opposite bet: that wisdom is personal, situated, and worth meeting one mind at a time.

Find your edge

Your edge lives off the average.

AI is the aggregate: every perspective averaged into one careful voice, serving the same answer to everyone who asks. Feed on it and you’ll think what everyone thinks. Perdisco feeds you the edges instead — distinct minds, in their own words, openly disagreeing with each other. Stack enough real vantage points and you get what no average can give you: a holistic model of the world, and a view the crowd doesn’t have.

Go deeper

Every claim carries its receipts.

Tap any insight and Perdisco opens the room it was said in — the moment from the conversation, the evidence behind it, and the source it leans on. Agree or push back; we just insist you know why.

Opinion · Ridgeway survey

Taste is the compounding asset — skills depreciate, judgment doesn’t.

The author’s hiring rule after two decades of funds: tools change every five years, but the people who notice the right things keep getting more valuable. Taste, here, means calibrated judgment — knowing what good looks like before the metrics agree.

From the source

“Every skill I hired for in 2015 is automated today. Every judgment call I hired for still isn’t.”

Ridgeway longitudinal skills survey, 2024

Half agree — taste still needs reps. You can’t notice what you’ve never built.

Your knowledge

A stack that remembers what you want to keep.

Interactive practice

Not memorization — calibration.

Flashcards, applied quizzes, matching rounds — and predictions you back with earned tokens, settled when the future shows up. None of it is about reciting someone else’s conclusions. It’s reps for your judgment: test an idea against your own, keep what survives, and feel your model of the world click a notch truer.

  • Flashcards that re-open ideas, not recite them
  • Applied quizzes that stress-test ideas in new situations
  • Predictions that score your calibration against reality

Tap the flashcard.
