I leave myself open to reading dissenting writings around such "ugh topics". I mostly motivate myself with a smug sense of superiority and the ability to mock their obviously poor reasoning. I don't seek it out, but I have intelligent friends with the occasional stupid philosophical attachment, so I get linked to fairly high-quality articles from a variety of perspectives.
The end result is that I often reinforce "this idea is clearly stupid, since the people defending it can't mount an intelligent defense". Occasionally, however, I go "oh, I never thought about it that way!" and realize that the majority of my objections just got wiped away, at which point the "ugh field" usually goes away and I can re-evaluate the idea.
So, basically, I let myself openly mock ideas I disagree with, because it tricks me in to having an actual discourse, and I trust myself to recognize novel arguments and information well enough to actually integrate them. It helps that I have no objections to mocking an idea I don't understand, so this doesn't impact my social status in cases where conceding the debate would look bad. I've occasionally argued against a point long after accepting it, then just quietly reversed my opinion a few days later to save face. I don't know how helpful this is for other people, but it helps me strike a very nice balance between social and intellectual values.
Related to: Ugh Fields
Ugh Fields are internal negative reactions that occur before the conscious mind has an opportunity to process the information, often resulting in less than optimal decision making.
We have previously discussed Ugh Fields that involve performing tasks, but as far as I can tell we haven't had any posts on Ugh Fields about ideas. Ugh Fields towards ideas can be experienced both while trying to weigh the merits of an argument, or after one's opinion has altered.
On Less Wrong, many ideas are accepted as true that, in some places, have negative connotations. And if someone has an Ugh Field towards an idea because of this, it can be difficult to change this to a neutral or positive position. This can cause problems while trying to think about these ideas rationally.
For example, I grew up in a heavily liberal household. And because of this, when I was young I had a negative view on libertarianism. This caused problems, to the point where in my early teenage years I didn't weigh someone's economic views as highly just because they identified as a libertarian. But, once I actually looked into the policies of libertarianism and the results of these policies, my views shifted. And although my reaction improved over time, I still flinch away when I hear the word "libertarian," despite considering myself one!
And there are many other topics on Less Wrong someone could have this reaction for, including AI, FAI, atheism, transhumanism, cryonics, immortality, alternative diets, optimizing utility for charities, and metaphysics. An Ugh Field towards any of these ideas can hinder one's ability to update properly on hearing information about it.
