In addition to the science of history, which was regarded as an auxiliary science of ideology, and the classical languages, which were removed from the curricula along with theology, the teaching of heredity and psychology were the two fields of science which suffered most during the Stalinist period.
Lisaks ajalooteadusele, mida nõukogude võim käsitles kui ideoloogia abiteadust ning klassikalistele keeltele, mille õpetamine koos teoloogiale tehtavate takistustega lõpetati, olid stalinismiperioodi kaks enim kannatanud teadusvaldkonda pärilikkusõpetus ja psühholoogia.
