Bias is somthing that has been around for ages, favouring one thing over others, such as sharks over dolphins, or one sport over another. Here, we have two sites about the worlds greatest chemists, the first one I read had a good mix between people from different places and genders, and on the second one it was a voting poll, people voted the best chemist as Marie Curie, a woman, I say that both weren’t bias. The first one we ever read as a class was about old white men… No people of color or women, or LGBTQ+ or any minority. I would trust the second two over the first one. In the end, when writing something non-fiction, don’t be a biased swear word.
