There is a conception that a uniquely positive correlation prevails between
the intake of alcohol and creativity, but only a few experimental studies
address this. subject. Existing studies together with recent experiments ar
e reviewed. This later series of experiments explored whether or not modera
te alcohol intoxication (1.0 mi of 100% alcohol/kg body weight) facilitated
different phasesof the creative process, i.e. preparation, incubation, ill
umination, verification, and restitution. A hypothesis is derived: which po
stulates that modest alcohol consumption inhibits aspects of creativity bas
ed mainly on the secondary process (preparation, certain parts of illuminat
ion, and verification), and disinhibits those based mainly on the primary p
rocess (incubation, certain parts of illumination, and restitution).
