Bias: Inclination for or against a particular of several alternatives, usually without good evidence.
As defined, a bias need not be as strong as a prejudice and may be easier to admit by a person who has it. Also, one may be biased on moral, personal or emotional grounds, while allowing one is biased that way. Then again, many biases are unconscious, at least in the sense that those having them are not aware their judgments about what the facts are may be or are slanted by their biases.
There are quite a few more, but less visible, for I found quite a few titles had not been properly updated. This I did straighten out today, but the whole Philosophical Dictionary needs some straightening out and updating. But then, as usual, I do as I can, not as I want.
In case you're interested in propositional attitudes, Personal Perspectives may be interesting, though this item requires some formal reasoning also. Then again, the former of these, at least, also needs straightening out.
