INTRODUCTION

CORE DEFINITION

PAPRIKA, short for Potentially All Pairwise RanKings of all possible Alternatives, determines a ranking consistent with a decision maker's preferences through pairwise comparisons. The method presents two alternatives at a time and asks which is preferred, selecting pairs designed to be informative, and eliminates dominated alternatives as comparisons accumulate. Criterion weights are not requested directly, because the comparisons implicitly constrain them. The output is a complete ranking consistent with the stated preferences. The method assumes preferences are stable and internally consistent, since contradictions have no natural resolution.

SCAFFOLDING EFFECT

psychology

Reduce cognitive load

- Use pairwise presentation: compare two alternatives at a time instead of filling in a weight table. - Use informative pairing: choose pairs where each option wins on some criteria, so the comparison is meaningful. - Use elimination: drop alternatives that lose consistently before running further comparisons.

Asking for explicit weights requires the decision maker to translate a preference structure into numbers, which most people cannot do reliably and which invites later dispute. Pairwise comparison asks a question people can answer, and the answers jointly constrain the weights, so the same information is obtained indirectly. Careful pair selection matters because uninformative pairs, where one option dominates on every criterion, add nothing. The method trades many simple judgments for one difficult one, and inconsistent answers cannot be reconciled automatically.

MINIMUM ACTION

In progress 0/1

Practice this model in one real situation:

List the alternatives and the criteria that distinguish them. 2. Present two alternatives at a time and ask which is preferred. 3. Choose the next pair so each option wins on at least one criterion. 4. Eliminate alternatives that lose consistently as comparisons accumulate. 5. Read off the final ranking and check it against the stated preferences.
