Magic mushrooms. A Washington Post article reported that psilocybin, the active ingredient of “magic mushrooms,” promoted a mystical experience in two-thirds of people who took it for the first time, according to a study published in the online journal Psychopharmacology.

The authors of the article stated that their “double-blind study evaluated the acute and longer-term psychological effects of a high dose of psilocybin relative to a comparison compound administered under comfortable, supportive conditions.” Explain to someone who knows no statistics what the term “doubleblind”

means here.
