Claim
Phase two had 96 volunteers who were dosed with LSD in the evaluation of the possibility of intelligence uses of the drug.
Correction

The Senate hearing record gives the phase-two count as 95 volunteers, not 96.

Full reasoning

The article's breakdown of the Army LSD program appears to draw from the 1977 Senate MKULTRA hearing record, but the volunteer count for the second phase is misstated.

That hearing describes the second phase as "Material Testing Program EA 1729, 95 volunteers" and separately describes THIRD CHANCE and DERBY HAT as involving 16 unwitting nonvolunteer subjects. In other words, the official Senate count for phase two is 95, not 96.
