Methods
Idea screening
Rank a long list of rough ideas on appeal and uniqueness, so only the best few get a full test.
Monadic test
Each person sees one concept, which gives the cleanest read to hold against your action standard.
Sequential monadic test
Each person rates several concepts in rotated order, so you need fewer people per concept.
Protomonadic test
Rate concepts one at a time, then pick a favorite head to head, so you get both scores and a winner.
Concept scorecard
Top-2 box on purchase intent, uniqueness, relevance, believability and value, with significance letters and the top like and dislike.
Screen the whole shortlist first
An agency test is priced per concept, so teams cut ideas before anyone sees them. Twins let you score all ten, and real interviews go to the few that earn them.
Scores with the why attached
A rating tells you a concept is weak. The interviewer asks what drove it, so each concept comes back with its top like, its top dislike and the words people used.
Fix it and test again
A concept that misses is often one phrase away. Reword the claim, rerun it on twins in minutes, and send the new version to people the same night.

Questions
What is the difference between monadic and sequential monadic testing?
In a monadic test each person sees one concept, so there is no comparison bias but you need a separate group per concept. In sequential monadic each person rates several concepts in rotated order, which needs fewer people but lets earlier concepts color later ones.
What metrics does a concept test measure?
Purchase intent is the main one, usually reported as top-2 box: the share who say they definitely or probably would buy. Most tests add uniqueness, relevance, believability and value for money, plus open questions on what people liked and disliked.
What is an action standard?
It is the bar a concept must clear to move forward, set before fieldwork. For example: top-2 box purchase intent of 45% or more, and significantly ahead of the current product. Jean has no category norms of its own, so most teams set the bar from their own past tests.
How many people do I need per concept?
For a monadic read, 100 to 150 people per concept is common. At that size, gaps under about ten points are hard to call. Twins let you add hundreds per concept at the screening stage at little cost.
What kinds of concepts can I test?
Anything you can show as text, an image or a video: product ideas, packaging, claims, names and positioning lines. Jean does not run in-store or in-home product use tests.
Are digital twin scores accurate enough to make the call?
Use twins to rank and cut a long list. Make the final call on the concepts that survive with real interviews, which Jean runs overnight.
