Public attention evaluation by KJ method and AHP method are typical methods for evaluating alternatives subjectively. It is necessary for participants to be confident of recognizing their problem chart for getting a common agreement. The problem-chart type is different from each other. The judging way is different too. In the KJ method, participants should evaluate alternatives holistically by using KJ chart. In the AHP method, however they should do alternatives analytically by using a hierarchy chart. The purpose of this study is to report the result of comparative experiments on three points of view. The first view is to clarify the differences seem in common understanding between the groups who make KJ chart and the groups who do not. The second is to clarify the differences seem in potential reliance between public attention evaluation of KJ method and AHP method. The third is to make the differences clear in readability between KJ chart and hierarchy chart. In the experiments, twenty examinees were separated into five proups. Only two grpups made KJ chart. The two groups of the public attention evaluation and other two groups of the AHP evaluation repeat evaluations three times by adopting the Delphi method. The examinees belonging to the other one group were further separated into two sub-groups; One sub-group examined public attention evaluation by using KJ chart, the other did by using hierarchy chart in the same way. As a result, the groups who made the KJ chart got more common understanding than other groups who did not. The public attention evaluation in KJ method was more reliable than AHP evaluation. But the KJ chart group members are not so good as the hierarchy chart group members in readability.
