A bias is a prejudice. One is said to be biased if one is influenced by one's biases. A bias could for example lead one to accept or non-accept the truth of a claim, not because of the strength of the claim itself, but because it does or does not correspond to one's own preconceived ideas.

An example of bias is having an Americo-centric point of view (the point of view of an American, in particular one from the US), or similar for another country.

A systematic bias is a bias resulting from some system. For example, a committee on evolution that meets in a Christian church and is primarilly advertised through fliers in Bibles may have a bias towards Christian views of evolution.
