The question is what direction that's in. Activism that is, in essence, urging the adoption of ones findings, if obtained through valid experiments, isn't really biased. Politically-oriented think-tanks are looking to build research that supports a particular political outcome. That's a pretty strong contrast to say "We have found that X is harmful, and will advocate for people having reduced exposure to X." Consider, for example, the number of infectious disease epidemiologists, vaccine developers and doctors who have essentially been forced to engage in "activism" thanks to anti-vaxx movements.
