Economists just don't look very ideological

Noah Smith asserts that Economists just don't look very ideological.

So political ideology, as far as we can tell, just doesn't explain much of the variance in academic economists' policy recommendations. Keep in mind that absence of evidence is not evidence of absence - the authors simply might not have measured ideology accurately.

But given the fact that economists deal every day with topics that are inherently political, I'm surprised we don't find more bias in paper-writing.

And there's also the possibility that the sample is heavily influenced by a few outliers. There are a couple of departments out there that may be influenced by big donations from political activists. That might inject a few politicized folks into the academic mix,

So overall, I think my thesis that most of econ doesn't line up along left-right political lines seems like it's borne out by the data. Still, that leaves the possibility that a few policy issues, or a few top economists, might be strongly motivated by political ideology. I'm sure we can all think of one or two anecdotes.

Emphasis Mine

Or, the ideological differences allowed Capitalism are really not measurable.

For instance, the idea of Capitalism cannot be challenged. An analysis of alternative economic systems cannot be treated sympathetically.

There is an academic bias that is due to the nature of the Capitalist society. Academia is part of the ideological superstructure that exists to mould the minds of workers into supporting the system that exploits and crushes them.
