  For any given case of disagreement between just two people, the odds are that they will not be equivalent on all Disagreement Factors: \(X\) will surpass \(Y\) on some factors and \(Y\) will surpass \(X\) on other factors.  If you are convinced that a certain person is clearly lacking compared to you on many Disagreement Factors when it comes to answering the question ‘Is \(B\) true?’ then you’ll probably say that you are more likely than she is to answer the question correctly provided you are not lacking compared to her on other Disagreement Factors. If you are convinced that a certain person definitely surpasses you on many Disagreement Factors when it comes to answering ‘Is \(B\) true?’ then you’ll probably say that you are less likely than she is to answer the question correctly provided you have no advantage over her when it comes to answering ‘Is \(B\) true?’. If you think the two of you differ in Disagreement Factors but the differences do not add up to one person having a net advantage (so you think any differences cancel out), then you’ll think you are peers on that question.
