Abstract
INVESTIGATIONS into the relationship between evoked potentials and human intelligence have been carried out by Ertl1, who claims to have found no evidence to support my earlier conclusion2 regarding this relationship. In my opinion, Ertl's work supports my conclusion that there is a significant difference between the evoked potentials for high and low intelligence groups. Although Ertl uses a Fourier analysis rather different from my own analysis, it should be possible to relate the two investigations (see, for example, ref. 3).
