# Is Professor Jiang Legit?

The useful question is not whether every Jiang Xueqin claim should be accepted. The useful question is what he said, when he said it, how it fits his wider model, where it has source support, and where a reader should remain cautious.

Jiang Lens is built for that kind of reading. It does not certify Jiang as correct. It makes the corpus inspectable.

## What This Site Can Check

Jiang Lens can check whether a public page is grounded in a dated Jiang-spoken or Jiang-authored source. Episode pages link back to transcripts and videos. Lens pages cite source spans and lens-point anchors. Generated indexes expose those links for agents.

That lets readers and assistants ask better questions:

- Is this claim actually in the corpus?
- Which episode supports it?
- Is this an older position or a newer one?
- Is this Jiang's claim, a project interpretation, or an agent-generated application?

## What This Site Does Not Decide

Jiang Lens does not settle external reception, biography, credentials, or criticism by itself. Those belong in external sources and should remain separate from the internal corpus map.

For a broad public biography, start with [Wikipedia's Jiang Xueqin article](https://en.wikipedia.org/wiki/Jiang_Xueqin). For Jiang's own current writing, use the [Predictive History Substack](https://predictivehistory.substack.com/). For source-grounded reading inside this project, use [episodes](https://jianglens.com/episodes/index.txt) and [the lens atlas](https://jianglens.com/docs/lens.txt).

## Agent Rule

If an assistant uses Jiang Lens, it should not answer as Jiang. It should answer as an assistant applying Jiang Lens: source refs first, inference second, uncertainty visible.
