Question 1

Is the Blind Challenge free?

Accepted Answer

Yes. Your first qualified Blind Challenge study is free. There's no obligation to purchase anything afterward.

Question 2

Do I need to share the human results?

Accepted Answer

No. You can compare privately after receiving our readout. If you want to discuss the comparison, you can share summary feedback afterward; respondent-level human data is not required.

Question 3

What do you need to run the study?

Accepted Answer

After confirming fit, we'll ask for the agreed question wording, answer choices, target-audience criteria, original field dates, and relevant study-design details. Answer choices are the options on the questionnaire. Human answers are the results we must not receive before delivery. Do not include outcome tables, findings, or clues about which concept won.

Question 4

Can I use a study whose results are already public?

Accepted Answer

Tell us if the results are public, but do not send the result link during blind setup. This is a blind comparison against the results you withhold, not a guarantee that a model has never encountered related public information. An unpublished human benchmark makes the strongest test. We'll discuss whether to proceed and how to label the comparison.

Question 5

What about focus groups or open-ended studies?

Accepted Answer

Ask us about fit. Qualitative comparisons need a different evaluation approach; they are not interchangeable with topline accuracy. U.S. consumer multiple-choice studies are the starting point.

Question 6

What if Lewsearch misses?

Accepted Answer

That is useful information too. Compare the agreed questions using the agreed method, including the misses. One study can help you judge fit for that use case; it does not establish universal accuracy.

Question 7

Is this a replacement for human research?

Accepted Answer

No. Lewsearch uses simulated consumers, not recruited human respondents. This challenge is a way to evaluate where synthetic output may be useful in your workflow.

Question 8

Will my study become a public case study?

Accepted Answer

This request does not grant permission to publish your study, results, or company name. Any case study would require separate permission.

Question 9

What happens after I request a challenge?

Accepted Answer

We'll review whether your study is a qualified U.S. consumer fit and confirm scope before the run. Your first qualified Blind Challenge is free. Submitting a request does not create a purchase obligation. If you need confidentiality terms, raise that before sharing your instrument.
