Personality quiz logic is set up where each answer choice gives a point to one or more of the results of your quiz. When someone takes your quiz, they will be accumulating points for the different results based on their answer choices, and whichever result they have the most points for after answering all the questions is the result they will be shown.
Step 1: From your Interact Dashboard click "Edit" on the quiz you are adding logic for.
Step 2: On the left sidebar click "Questions" and then click on the question you want to add logic for.
Step 3: Click "Edit Result Correlations" either above the question or below.
Step 4: Connect answer choices to results by first clicking on the answer choice and then linking it to one or more results. Each line represents a +1 for correlated result, and as a quiz taker answers the questions of your quiz they'll be getting +1's for the different results. Whichever one they have the most of is the one they'll be shown at the end. You can also show a ranking of top results for a quiz taker if you choose.
A note on quiz logic accuracy: There are two important things to make sure your quiz is accurate.
Every result should have the same number of possible points associated with it. Meaning that as someone takes your quiz there should be the same number of total correlations for each result. The easiest way to do this is to have the same number of answer choices as results on each question and then link one answer choice to one result for every question.
In order to avoid a quiz taker getting a tie for two results, create an offset number of total possible correlations for each result. What I mean is that if you have four results, then have five total possible points for each result, that way you won't end up in a situation where the quiz taker chooses four for two different results. Generally to make a quiz accurate you want to have at least five total possible correlations per quiz result and you want the answer choices to be differentiated enough so people are incentivized to choose different options as they answer your quiz questions.
