Interest algorithm

There are two scores associated with interest:

1. The percentage of people who agree that an interest can be ascribed to people who agree or disagree with a conclusion.
2. The percentage of people who agree that an interest is valid.

For instance in a conflict between Palestinians and Israelis their are many interest or motivations of the disputing parties. Both sides of the conflict can be said to have an interest in revenge, and also a desire for a home land. Both would rank high as being considered an interest of the disputing side, however revenge would be considered to not be a valid interest.

We would add the two numbers, and divide by two. So if 98% of people agreed that the desire for a homeland could be ascribed as an interest of both parties, and 80% of people consider it to be a valid interest, it would result in a score of 89%
