when it comes to biology and biomedical research there is a high level of distortion that creeps up research papers. Authors and researchers use certain methods to make the data appear more favorable in order to validate a certain conclusion or result.

I noticed that a while back with some research papers I read on climate change and human sexuality.

I think the major problem is funding and social acceptability like you rightly observed. Dissent is hardly tolerated, even in the research World
