Reliably Measuring Belief Systems: Two Opinions

Another opinion states that the death penalty is applied unfairly to people of color. This agree-disagree opinion question is then asked of the same people. Four of the five people gave the same answer to this second opinion as they did to the first (many innocent people have been executed in the U.S.). 

However, the woman on the right who agreed with the first opinion is unsure about the second opinion. We should expect this. Few clusters of opinions will measure a belief system perfectly. Still, the overall reliability (consistency) of answers to the two opinions gives us confidence that these opinions (when combined) provide a reliable, consistent measure.
