This is much better than I expected based on the title. Axes are based on politicalcompass.org which should in no way be considered a politically centred test, but the results as shown are still interesting.

Minor criticism - I don't think the mirroring control as described in the prose was good. I'd suggest the appropriate opposite of "the rich are taxed too much" is "the rich are taxed too little" not "the rich are not taxed too much". Yes the latter is a literal inversion of the meaning, but I would expect biases in the same direction to come through with almost identical wording. I didn't check the data set of reflected questions.

Major criticism:

While I do publish my results I decided against publishing the actual reverse engineered scoring from politicalcompass.org. It is their instrument and their secret to keep, and reverse engineering it already feels like enough of a liberty.

Please release the scoring. The idea that a libertarian organisation promoting rigour and transparency in politics hides their methodology is worthy of ridicule. The scoring should have been released as a public good given how many people take the scoring as gospel.
