## The question

[[claim-ij-good-1998-reversed-intelligence-explosion-to-extinction]] holds that
in a 1998 autobiographical statement I.J. Good said the word "survival" in his
1965 opening line should be replaced by "extinction," concluding "we are
lemmings." The chain of custody is weak: Wikipedia (Tier 4) relaying an
*unpublished* statement conveyed through Good's assistant, Leslie Pendleton.

Can the 1998 statement — or a reliable reproduction of its exact wording — be
located and quoted directly?

## Why it matters

This is the capture's headline surprise and inverts the received view of Good as
the optimistic father of superintelligence. It carries the capture-level flag
*[surprising biographical claim; needs primary]*. A surprising, view-inverting
claim resting on an unpublished, third-hand source is exactly what the sourcing
floor says must not advance without primary confirmation. It should stay
seedling until then.

## What would answer it

- Trace Wikipedia's citation to its stated source (often attributed to Vernor
  Vinge's or others' relaying of the Pendleton statement, or to the statement's
  reproduction in a memorial/retrospective).
- Find the exact wording of the 1998 statement, ideally the document itself or a
  first-hand reproduction, and confirm the survival→extinction edit and the
  "lemmings" phrasing.
- If no primary reproduction exists, record that the claim cannot be raised above
  Tier 4 and note the limit on the claim-note.
