For Andreas Bikfalvi, medicine is a humanist activity that must protect itself against constructivist, racialist and "differentialist" ideologies. If the social sciences are very affected by identity ideology, the hard sciences and even the biomedical sciences are not exempt. A search on the scientific platform Pubmed NCBI with keyword racism ou intersectionality shows amazing things. For racism, In 2010 there were only 107 entries, with a sustained increase to reach 1 articles in 255. Furthermore, in 2020 there were 2018 entries and in 636 there were 2019 entries, which means an increase of 774% in just two years, and 100% in just one year. Before 62, the number of entries had remained at a very low level. For intersectionality, there were only 13 entries in 2010, with, in 2020, 285 entries. The increase of these two keywords therefore follows a parallel evolution. This is certainly explainable by recent events in USA, following the emergence of "social justice" activist groups, in the wake of the Black Lives Matter movement, which have had a significant impact on various academic institutions. This does not therefore reflect the increase in racial problems, but a recent importation of these issues into research.
