How does a layperson make a deeper investigation on their own? The research is typically paywalled, the jargon is inaccessible, the experiments are prohibitively expensive, etc etc. In effect, there is a priestly caste, and one which arguably excludes from the debate members of the skeptic's tribe (i.e., "people the skeptic might trust to address their concerns"). This is why heterodoxy and political diversity in the academy is soooo important.
You might be inclined to say something like "conservatives select out of the academy" or "it's not my fault reality has a liberal bias" and you might even be right, but I don't think you'll find climate change very sympathetic to your position. In other words, this isn't affirmative action for conservatives, it's affirmative action (of conservatives) for the benefit of humanity.
Disclaimers: I'm picking 'conservatives' and 'liberals' here because that's clearly the bent of the article. I'm also picking climate change since it seems to be the favorite example of science denialism. Of course, contrary to the angle of this article, science denialism isn't even an exclusively conservative phenomenon (blank slatism is a favorite of anti-science leftists--including leftist academics--and flat-earth and anti-vax are bipartisan beliefs).
