>>13136258>For example I was trying to figure out the pros and cons of hunter-gatherer vs agricultural society and the only relevant read I could find was ‘The Worst Mistake in the History of the Human Race’.This is the very first link that comes up when I googled this phrase, which makes me think you didn't look for very long. Check other sources, search for different combinations of terms, try searching libgen or Amazon or your uni library for keywords. You're likely going to have to collect little bits out of various places rather than finding one article that tells you everything you want.
Although you're never going to find totally "unbiased" information when you're looking for something which is fundamentally a value judgment. You can't list off all the things that are good and bad about a society in an "unbiased" way. The closest you can get to no bias is coming up with the pro/con points yourself and then looking for raw data to support it. Then there's only your own bias involved, which is there anyway.
Bias doesn't necessarily invalidate a book or paper though. Almost everything is biased to some degree. People warn you about bias because it's important to be aware that the author is a person with an opinion who is collecting and interpreting facts to support it, so you think about what you read rather than just slurping it down without challenging it. As long as the person isn't so strongly biased they start lying or grossly misrepresenting things there's still value in what they're saying.
