If it's worth saying, but not worth its own post (even in Discussion), then it goes here.
Notes for future OT posters:
1. Please add the 'open_thread' tag.
2. Check if there is an active Open Thread before posting a new one. (Immediately before; refresh the list-of-threads page before posting.)
3. Open Threads should be posted in Discussion, and not Main.
4. Open Threads should start on Monday, and end on Sunday.
Unfortunately in writing the article Vox themselves seem to have fallen prey to some of the same stupidity; if you're familiar with Vox's general left-wing sympathies you'll be unsurprised that the examples of stupidity used in the article are overwhelmingly from right-wing sources. If you really want to improve people's thinking, you need to focus on your own tribe at least as much as the enemy tribe.
I previously wrote about this here.
The example they give is actually anti gun control (it is a contrived example of course) and they repeatedly mention that the biases in question affect individuals who identify as left-wing as well as individuals who identify as right-wing.
Why? I looked at your linked article and the two articles it links to and I can't find any proof that doing what you say would result in fewer disagreements than not doing that.
