Since its inception as a field of science in the 19th century, psychology as it is now offered at universities has made great efforts to become a quantitative discipline on par with the natural sciences.

The impact of this kind of science has sometimes been downright disastrous; for example, in connection with immigration, forced sterilization, university admissions or the debate on racial differences.
