{"v":"<p dir=\"auto\">From Jane (7 Oct 2026):<\/p>\n<blockquote>\n<p dir=\"auto\">Not Known doesn&#39;t do much. The &#34;Answer it instead&#34; is just sending people round in a circle to ask the same question again. If there are fields where we need to keep track of unknowns we should record it that way. I think getting rid of it is best. Leaving a field blank means they don&#39;t know. However, if it&#39;s a required field we need to know what to do.<\/p>\n<\/blockquote>\n<p dir=\"auto\"><strong>Where it is<\/strong><\/p>\n<ul dir=\"auto\">\n<li>The &#34;Not known&#34; link and the &#34;Answer it instead&#34; link under a question: <code>pages\/visit-v2.php<\/code> (around line 904\u2013919).<\/li>\n<li>Offered only where a question has <code>allow_unknown<\/code>; recorded as an <code>unknown<\/code> answer: <code>code\/form_v2_visit_rules.inc.php<\/code> (around lines 343 and 656\u2013666).<\/li>\n<\/ul>\n<p dir=\"auto\"><strong>Proposed<\/strong><\/p>\n<ul dir=\"auto\">\n<li>Remove &#34;Not known&#34; from the visit screen.
