Opinions on politics, nationality, energy religion etc., are often decisive and uninformed:
Informed opinions tend to be widely spread, but some opinions become polarised, with “no-man’s land” between, defined by one single bit. In the same way that digital signals are immune to interference and noise, binary opinions are immune to learning.
We hunger for simple descriptions of complex scenarios, and are often more interested in finding evidence to support our position (and that of our peers), than in finding the objective truth (which can be frustrating!).
