Perhaps I’m just wrong but as a non-economist observer, it feels like a lot of econ studies somehow seem to agree with the political leanings of the authors, irrespective of whether they’re left- or right-leaning.

Is this just a twitter thing or is there more to it?

Tbf, this is also possible in engineering. For example, LCAs can give diverging results depending on system boundaries & assumptions. But difference is
1) many LCAs for same system to compare
2) Easier to spot why results differ
3) Typically not correlated with political leaning.

Another eg. is energy system models where you can use model construction & assumptions to favor one or other technology. But, even in this case, there are many models to compare results to, outliers can be quickly dissected, & correlation with political leanings is not obvious.
