The scientific method: a hard discipline

This is true even for scientists, because they’re exposed confirmation bias too (searching for and picking up only evidence that confirms what someone already believes).

But unlike the rest of us, they submit their ideas to formal peer review before publishing them. Once their results are published, other scientists will try to reproduce them (if they have enough relevance and importance) and, being naturally skeptical and competitive, they will denounce them if they don’t hold up.
