Unknown answer option in MSA Research

The UNKNOWN answer option is available on the platform for every question (hard-coded), so that researchers can signal that they looked for the answer, but could not find it in the sources they assessed (which would be the sources they cite).

HOWEVER, in those cases, the company may have disclosed the answer in another source.

Because the metric questions for this particular project only apply to a company's MODERN SLAVERY STATEMENT, "Unknown" is NOT an option. The company either provides the answer to the question in this statement, or it does not.

The reason we are so strict about this, is that the statements are legal documents (hence the need for a signature), and so whatever companies report about their anti-modern slavery activities in other documents falls outside the realm of legal influence.

This means your "UNKNOWN"s should turn in to "NO"s, and you can then clarify in the comments that the topics are touched upon in the statement but that they do not provide enough details to warrant one of the other answer options.
