This is why the last step of science is broad consensus, which has solved literally every single example of bad science in this entire thread. All this means is people should pay more attention to sources.

Even if you follow the rules strictly, confirmation bias can kick in... which is basically "always" because you have to start somewhere and will think a certain way.

Based on that argument, why bother? /s

Does anyone remember all the bogus studies that showed smoking was healthy?

Let's also not forget that Scientists are also humans. Humans with their own beliefs and biases which do get transferred into studies. Peer review can help reduce that but since peers are also humans with their own biases, but also common biases shared amongst humans it's not bulletproof either.

There will always be some level of bias which clouds judgement, or makes you see/think things that aren't objectively true, sometimes it comes with good intention, others not so much. It's always there though, and probably always will be. The key to good science is making it as minimal as possible.
