The solution to this problem is to use attribute weights. An attribute weight is a multiplier you apply to each attribute that compensates for some attributes being more important than others. When setting up the data at first, using 1.0 is a nice neutral starting point. It indicates that all attributes are equally important and lets you get through the data entry process more quickly. When you begin testing, you are likely to find that the attributes are not of equal value, and they need to be modified with weights. In the racing example, testing shows you that top speed is more important than acceleration, and horn loudness is not very important at all. You can use these observations to inform your first pass with weights, which might look something like this: A boat has two attributes: Speed and Turning. In this game, speed is considered to be twice as valuable as turning. Which of the following sets of attribute numbers counteract these weights to make the two attributes of equal value? Speed 2, Turning 2 Speed 100, Turning 75 Speed 10, Turning 5 Speed 12, Turning 24
