An article about my friend Jim Fadiman and his LSD research includes this awesome bit about his last experiment in the 1960s (conducted on a group of "an architect and three senior scientists—two from Stanford, the other from Hewlett-Packard" who had "each brought along three highly technical problems from their respective fields that they’d been unable to solve for at least several months") before the government shut down all LSD work:
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.
Ah yes, those crazy druggies.
Though the one time Hermann Kahn took psychedelics he supposedly spent two hours saying "Oh, wow," and claimed afterwards to have come up with a new system for prioritizing nuclear targets. I never believed that story. Maybe I should.
