The Altered West Report

A documented finding, replaced by its own denial before it reached the people investigating it.12

Documented connection

By the sworn 2026 testimony of Tom O’Neill, Louis Jolyon West’s 1956 MKUltra report stated: “It has been found to be feasible to take the memory of a definite event in the life of an individual and through hypnotic suggestion bring about the subsequent conscious recall to the effect that this event never actually took place, but that a different (fictional) event actually did occur.” The version turned over to Congress in 1977 had been replaced with a four-page summary “clearly written by another hand,” which concluded that LSD’s effect on dissociative states “has never been studied. Never been studied.” O’Neill located the substituted document’s facsimile at the National Security Archive.

Role in the thesis

The smoothing rail in a single artifact: not a destroyed file (that was 1973) and not a tidied summary at the podium (that was 1977), but the specific act of replacing a documented result with its opposite in the record handed to oversight. As the witness put it: an earlier committee “believed it had been told the truth about the program. It had not.” The finding required no conspiracy theory to be alarming; it required only the comparison of two documents.
