# Psycho-History

**Aliases:** psychohistory, Asimov psychohistory, science of imagining the future, predictive history method.

> **Fast answer:** In Jiang Lens, psycho-history is the long project behind Predictive History: building models that read past and present well enough to make testable future claims. Jiang anchors the word in Asimov's *Foundation*, but his version stays provisional, educational, and humanistic rather than a finished oracle.

## What Jiang Means

Jiang usually starts from Asimov: psychohistory is the imagined science of modeling large-scale human behavior across time. He then turns that fiction into a school problem. Students, historians, readers, mathematicians, programmers, and model-builders have to learn how to correct the past, test forecasts, and revise the analysis when predictions fail.

The human boundary is important. Jiang's psycho-history cannot be only quantitative statecraft. It has to model love, creation, learning, agency, compassion, and the human heart, because those are also causal forces in history.

## Where Jiang Says It

| Source | Timestamp / ref | What to inspect | Why it matters |
|---|---|---|---|
| 2025-06-13, [Predictive History Begins As A School](https://jianglens.com/episodes/predictive-history-voqeteh6hko.txt) | `video:predictive-history-voqeteh6hko@transcript:v1#seg-0005`, `#seg-0006` | Asimov and modeling past/present | Names the project source. |

## How To Use This Term

Use this term for Jiang's research ambition: a future-facing historical science disciplined by prediction and corrected by human complexity.

Do not use it as if Jiang claims to possess a complete mathematical oracle.
