• actively look for views "against" what we believe/learn - and trying to understand them
• this is a countermeasure for the feedback loop of looking for confirmation for what we believe, and learning only more confirmation, closing us from different views / the "truth"
• looking for confirmation is opposite of a scientific method - we have an outcome in mind and want to find points for supporting it, instead of starting from observations, and coming to a conclusion

Google the subject term or phrase followed by the word controversy or opposition... If you don't find a lot, try rebuttal, refuted, arguments against.
