But here’s the clincher. After their 5HT2A neural receptors simmered down, they remained firm: LSD absolutely had helped them solve their complex, seemingly intractable problems. And the establishment agreed. The 26 men unleashed a slew of widely embraced innovations shortly after their LSD experiences, including a mathematical theorem for NOR gate circuits, a conceptual model of a photon, a linear electron accelerator beam-steering device, a new design for the vibratory microtome, a technical improvement of the magnetic tape recorder, blueprints for a private residency and an arts-and-crafts shopping plaza, and a space probe experiment designed to measure solar properties. Fadiman and his colleagues published these jaw-dropping results and closed shop.
At a congressional subcommittee hearing that year, Sen. Robert F. Kennedy grilled FDA regulators about their ban on LSD studies: “Why, if they were worthwhile six months ago, why aren’t they worthwhile now?” For him, the ban was personal, too: His wife, Ethel, had received LSD-augmented therapy in Vancouver. “Perhaps to some extent we have lost sight of the fact that it”—Sen. Kennedy was referring specifically to LSD here—“can be very, very helpful in our society if used properly.””
