The problem with ideological science is that its "experts" are not people one can simply believe. If you are an optimist, you may believe their claims are not outright lies. But scientists are not heros, and scientists without permanent position, who have to hope for their next grant, are the opposite of brave warriors for truth. (With a few exceptions, which, after two years, are no longer scientists and even less "experts".) The typical reaction of scientists to political pressure is (1) to switch into another domain of research without such pressure, (2) not to study questions where the outcome predictably contradicts the political dogma, (3) Hide the results which contradict the political dogma behind professional language.

Scientific journals. The media simply distribute lies. Scientific journals distort the presentation under political pressure, but rarely lie openly. So, what distortions you have to expect? First of all, it will be much easier to publish a politically correct study than a politically incorrect one. Then, the politically incorrect parts of the studies will be hidden inside - title, abstracts, and conclusions tend to be much more politically correct than the other parts of the paper.
But, at a first level, to identify the direction of political pressure it is sufficient to compare what the media write (these lies are so penetrant and so often repeated that you know them even if you don't read them) with what the abstracts of scientific articles write. Then you can expect that the content is a further shift in the same direction, and truth is yet another big shift in the same direction.
How such a comparison of what the media write, scientific abstracts, and the actual content looks like, can be seen in another example of politically distorted "science", research about child labor. The test example was "
The Economics of Child Labor" by By Kaushik Basu and Pham Hoang Van, evaluated in

The choice was not my own - the article was presented against me, as providing support for my opponents, unknown to me before, in particular, at the time I have written the comments above. Thus, it is a quite independent test, with full support of several of the claims I have made:
1.) The abstract contains only a very moderate criticism of what is proposed by the media (the media argument "loses much of its force", conditioned by an "if").
2.) The content provides a further shift, describing the effects as harmful for the children and guided by protectionism as the hidden agenda.
3.) Then, I was able to identify serious flaws in the main content, which claims that
in some situations forbidding child labor may be not harmful but even useful. The argument itself has not yet been refuted, thus, is evidence for the hypothesis that toward truth we have yet to expect another shift in the same direction.
Note also that all three points are not based on some conspiracy theories, but on elementary economic considerations. The basic assumption is that scientists want to find the truth and distribute it, but, on the other hand, have to care about their career interests, which are endangered if they openly confront the positions of those in power. The incremental increase of truth content from media (0) to titles/abstracts (1), content (2), informal talks (3) and the own opinion is what has to be expected here, as well as that many scientists simply choose other research directions because such political pressure is unacceptable for them, so that the scientists remaining in the field are probably those which support the ideology behind the political pressure (which distorts the research itself).
