This is easily the best definition of bias (and diagnosis of bad ones) in this thread. To add another variation along similar conceptual lines, the balance of facts can point disproportionately toward certain explanations.
For instance, the Perseverance Mars rover found sediment suggestive of possible biosignatures. Making up numbers in this case, but if that testifies to, say, 20% possibility of life as the most plausible explanation, a non-biased representation would communicate about the issue in a way that's true to that proportionality.
Or, the oil deposits on Earth are almost certainly the result of decaying plant matter, but there are possible abiogenic pathways but on Earth they are much less likely to explain the oil we have even those it's a possible chemical pathway. Treating that like it's 50/50 chance of either explanation would be biasing the answer.
