Scientists who don't feel strongly about animal rights defend the position that is most convenient and efficient for them. If using a monkey instead of spending months cultivating petri dishes is easier (e.g. more deterministically successful for publication) then of course they will advocate for using the monkey. This argument leaves the animal rights activist unimpressed. In the end most animal experiments are certainly useful but few are strictly necessary. Researchers complain about all the paperwork required but I wish it was 100 times more difficult to get these experiments approved. Then people would really make sure the experiment is well thought-out and important. And I would happily delay some scientific discoveries by 50 years if that can spare a few million animals (thanks to better computer models or new noninvasive techniques)
