When your research stops being a quest for the answer, wherever the chips may fall, and becomes a steppingstone to continued funding, it is rare that the results desired by funding agencies will not affect the outcome, and if they do not, rarer still that the outcome will not affect funding. Those allocating the grant money often have a desired conclusion, and as such are not constrained by anything to fund other than what they want to hear.
It takes a commitment to the truth to resist such, something that used to be prized in the academic community but has been replaced by a neo-Lysenkoism that provides the results needed to drive agendae and impose control.
