Hi,
The most efficient solution here is probably to use javascript to randomly determine which premises you’ll pick as the first, second and third ones. And since you don’t need to do it during runtime, you can randomize those things for each trial when generating them, in the function you pass to Template
To give you an idea, you would start your Template command like this:
Template("fillers.csv", row => {
row.premiseIndices = [1,2,3];
fisherYates(row.premiseIndices);
return newTrial("filler-trial",
You can find the full code (and its demo) here: https://farm.pcibex.net/r/WKBLfB/
