Josef Mengele was intellectually curious. Being intellectually curious alone is no justification for the utter disdain and disregard for life, including animal life and suffering, and I think a person has to be very poorly developed as a human to believe it does.
And quite frankly, it strikes me that the ‘accumulated knowledge’ in science is often pretty much disregarded in pursuit of pointless, meaningless tests and experiments on animals just to suit the ‘intellectually curious’, because those people have bigger egos than hearts, or because for all their supposed scientific credentials they have forgotten to ask a few basic questions such as “is this really necessary?” “What value will this really bring, if anything at all?”
”Lindl et al. examined 51 animal experiments from the years 1991-1993 with regard to their relevance to humans 10 years on. They found that only 0.3% of the studies they examined showed a direct correlation between animal experimental findings and the results found in humans. But even in those the hypotheses confirmed by animal experiments could not be implemented in clinical therapies for humans. Either no therapeutic effect was detectable or the findings in humans even contradicted the results of the animal experiments (59). For lack of a “better” study, the German Primate Center in Göttingen even used the review article by Lindl et al. on its website until 2016 to justify basic research with monkeys. Thus, a 99.7% error rate was considered acceptable for the lottery that animal experiments are. ”
”In recent years, animal experiments in so-called basic research has increased continuously. In Germany in 1991, they amounted to 13%, whereas today almost 60% of animal experiments are conducted in basic research (54). One main reason for this increase is genetic engineering.
Basic research focuses on the curiosity-driven acquisition of knowledge. By definition, the primary goal is not a specific benefit, e.g. discovering a drug or therapy. Because of this, no limits are set to researchers’ ingenuity and there are many examples of frivolous experiments.”
