I'm trying not to biased, but can't stop to notice sometimes math seems to be biased when you don't like the result:

Saavedra had repeatedly complained about supposed bias in social media algorithms, including tweeting that “tech companies tend to be liberal & something is off with their algorithms because they won’t show a lot of content I find by manual search.”

That's not really a case of being biased when you don't like the result though.

That's a case of likely having a different bias than the people tuning the algorithm, and that happens all the time. You're sense of what is "correct" or "the gold set" is skewed by your own bias, and not everyone has the same bias. It's literally impossible to create results that everyone will find unbiased... and not surprisingly, the results companies end up going with are the ones that seem least biased to the people who work there.
