That situation is a bit different. Oil Companies performed proprietary research internally and promoted those results as scientific. Whereas, the implication in this post here is that anyone who ever worked for an oil company in climate science can no longer do climate science for an agency.

The insulin response you’re talking about is very small and it doesn’t lead to a chain reaction.

I think it’s sort of a catch 22. The people that tend to be the most knowledgeable about a particular science often have industry experience doing the exact thing you want them to study now. The idea that people could study the effects of aspartame for decades but are now “tainted” because they used to work for a soda company doesn’t necessarily square up to economic reality.

If however, you choose to put your foot in the sand there you’re going to have a bunch of people on a committee that have no idea what they are doing (which by the way people will also criticize you for) Remember when Trump appointed senior cabinet positions to people with completely unrelated experience? Such as Ben Carson (a former medical doctor) being appointed secretary of housing.

It’s a lose/lose situation I’m not sure what you all are expecting.
