Regarding your edit: what I'm looking for is a genuine AB test. Example: suppose there was one packet (mixed dry batter) or two, and for B the user had to mix them. The Ikea effect says B gets better customer satisfaction than A.
Someone downvoted all my comments in this thread. Apparently despite the fact that this is a product design guideline that in my opinion is easy (though not trivial) to test, either all the science in all the world can't test it, or we should accept the theory proposed in the article (that the Ikea effect is real, exists, and should he used in product design) without any testing.

Cargo cult, anyone? :)
