Research on genetic diversity and mate preferences in humans
Evolution and Human Behavior 31:8–58.
Tässä tutkimuksessa tutkitaan geneettisten tekijöiden, erityisesti pääasiallisen histokompatibiliteettikompleksin (MHC), vaikutusta kumppanivalintoihin ihmisillä. Tutkimuksessa havaitaan, että miehet suosivat MHC-epäsopivia naisia sekä lyhytaikaisissa että pitkäaikaisissa parinmuodostustilanteissa, kun taas geneettinen monimuotoisuus vaikuttaa sekä miesten että naisten kumppanivalintoihin eri parinmuodostustilanteissa. Tämä tukee MHC:n merkittävää roolia ihmisten kumppanivalinnassa ja viittaa siihen, että nämä mieltymykset saattavat toimia geneettisen monimuotoisuuden lisäämiseksi jälkeläisissä.

Research on inherited genetic differences and scent preference
Nature Genetics, 30:175
This study demonstrates that women can discern differences in male body odor influenced by a single variance in HLA (human MHC) allele, with a woman's capacity to distinguish and prefer certain odors notably being based on HLA alleles inherited from her father and not her mother; this suggests that paternally inherited HLA-associated odors influence odor preference and might function as social cues, even despite a milieu of potential odors derived from a variety of genetic and cultural factors..

Jung's psychological type theory comprehensible and applicable in daily life, underlining the principle that behavioral variations, while seemingly sporadic, are consistently orderly, deriving from intrinsic differences in individuals’ preferred use of perception and judgment.
