We show that only two simple trade‐off judgments are sufficient to determine whether the multiplicative multiattribute model assumes its additive form, regardless of the number of attributes in the model. This additivity condition offers a useful alternative to the test based on multiattribute lotteries commonly presented in textbooks. It can make the determination of additivity easier and more reliable. © 1997 John Wiley & Sons, Ltd.
