Meal Construction Test

Welcome! You are about to take a test on Lab in the Wild.

Can you create low carb meals that taste delicious?

In an increasingly ‘carb-avoiding world’, can you still eat delicious meals? Learn how good you are at finding low carb, yet delicious, replacements for high carb ingredients. Compare yourself to others!

The test typically takes 10 minutes to complete.

 

Can you create low carb meals that taste delicious?

Please read the following information carefully before proceeding.

Why we are doing this research: We are trying to understand how to design Artificial Intelligence (AI) that can help people in decision-making.

What you will have to do: You will be presented with a set of pictures of plates of food. We’ll provide you with the list of ingredients on each plate. Your task is to reduce the carbohydrate content of the presented meal by replacing one of its ingredients. The replacement you choose should also be similar in flavor to the original ingredient. Therefore, your job is to find an optimal replacement that both reduces the carbohydrate content and retains the original flavor of the meal as much as possible. In some of the questions, an AI system that will recognize the ingredients and will present its recommendations for optimal replacements. You will also fill out a questionnaire at the beginning and end of the experiment.

What you will get out of it? We will give you feedback on how well you decided which ingredients to replace and how you compare to others. The studies on this website are not for clinical diagnosis.

Potential risks: There are no risks anticipated in taking part in this study and you are free to leave at any time without penalty or loss of benefits to which you are otherwise entitled.

Privacy: Your responses will be kept anonymous. We do not collect any information that could be used to directly establish your identity.

Duration: Approximately 15 minutes.

By clicking the "I agree" button you confirm that you have read and understood the above and agree to take part in this research. Your participation is voluntary and you are free to leave the experiment at any time by simply closing the web browser.

 

Please tell us a little bit about yourself. Why?

These questions are optional, but if you could answer at least the first four, that would really help us.

Have you taken this test before? (important)

How old are you? (important)

First we want to learn a little bit more about you in order to understand your personal decision style when choosing between options.



 

Instructions

You will be presented with 12 questions about meal design. For each, you will choose to replace the ingredient highest in carbs with an ingredient low in carbs, but similar in flavor.


Here is what a typical question looks like:

Try to answer the questions as accurately as possible.

Great Job :)!

The main source of carbohydrates on this plate is: mashed potatoes.

Now for the real deal. It'll be the same as the practice you just took.

When you're ready, press next to begin the test!


Question out of

Question goes here

By replacing the ingredient highest in carbs on this plate, your goal is to make this meal a low carb meal while keeping its original flavor (as much as possible).




 

How was your experience?



 

How mentally demanding was understanding how this AI makes decisions?

    Very high

 

Now, you will complete the second part of the test!

Overall, your answers matched those of the experts for out of the 24 meals.



On average, you reduced carbs of meals by % and your replacements shared on average % of the flavor molecules of the replaced ingredient.


For the same meals, our experts reduced carbs of meals by % and their replacements shared on average % of the flavor molecules of the replaced ingredient.


Other people, who took the same test, reduced carbs of meals by % and their replacements shared on average % of the flavor molecules of the replaced ingredient. Their answers matched those of the experts % of the time.
