The ideas were later popularized by psychologist Hans Eysenck.

One of the key proponents of such theories was Hans Eysenck, a former professor at the Institute of Psychiatry at Kings College London.

In the early 1990s, Pelosi, a psychiatrist at Priory Hospital Glasgow, published two extensive critiques of the work of Hans Eysenck, a giant of 20th century psychology.

In the 1960s the German psychologist Hans Eysenck suggested the reason behind this difference lies in our environmental sensitivity.

Eysenck’s papers contained questionable data and results so dramatic they beggared belief, Pelosi concluded.
