Anyone actually doing research quickly learns to stop paying much attention to interpretation and to focus instead on the data. The effectiveness of correcting for attitude is too small to be worth bothering with. You look just at the data (and the methods). If you don't know how to look at the data--I'm sorry, but in very many cases you simply can't extract knowledge from the primary literature. You'll have to wait until the whole process of the scientific method writ large gets done with it; it might be decades before it's adequately settled (or people might lose interest and it might never be adequately settled).

It's a good reason to learn to understand data in those areas that you're curious about.
