In reference to your request for thoughts, It seems like in both cases you could have parties switch their professed beliefs about the systems, without actually switching their behavior. This kind of pivot can and does definitely happen among some politicians. Should a reference to it be included?

Here are some potential examples:

Parties currently opposed to taking action on Anthropogenic climate change:

"Anthropogenic climate change has models which explain it and data which confirm the models. And it is good as a practical matter, because it is predicted to cause some areas to become more temperate, which will increase the yields of particular crops, so unlike the opposing party, we don't need to do anything to keep anthropogenic climate change from happening."

Parties currently opposed to keeping minimum wages low:

"Minimum wage caused unemployment has models which explain it and data which confirm the models. And is is good as a practical matter, because it is predicted to increase automation in low skill fields, which will increase yields of particular services, so unlike the opposing party, we don't need to keep the minimum wage low."
