We discussed popper in some classes I took, the main theme for that for like an explanation yes it needs to be falsifiable, but also sometimes science is just "look I made a thing!" Or "look I found a thing!" And it's less relevant there. The unanimous belief accross different classes in the sciences I took was that yes, when we think about science we look at it from the perspective of falsification, but when we actually do science, we usually think of it as exploration until we have something we think falsifies the status quo or needs rigorous data collection to reject the mill. Nobody is really running an RNA sequencing experiment to evaluate the impacts of a drug on the rna transcriptome with falsification in mind (even if in a sense the null of "nothing changes" is what you're trying to falsify"). Psychologically it's just seen as some exploration to see what happens.
