I'm just reading Kuhn book an scientific progress. In it he gives the example that chemists had a different opinion on the question whether a helium atom is a molecule than physicists.
The answer to such as "Is a A a B" can tell you often more about the person you are talking with than it tells you about the A and B. When looking at the notion of biases of Kahnemann I don't think that "having your attention grabbed by quarrels" is a cognitive bias.
If it's worth saying, but not worth its own post (even in Discussion), then it goes here.
