		<summary type="html">&lt;p&gt;basic page&lt;/p&gt;
&lt;p&gt;&lt;b&gt;New page&lt;/b&gt;&lt;/p&gt;&lt;div&gt;{{stub}}&lt;br /&gt;
&lt;br /&gt;
When it comes to knowledge in general one can categorize it into four areas:&lt;br /&gt;
&lt;br /&gt;
* 11 known knowns&lt;br /&gt;
* 10 known unknowns&lt;br /&gt;
* 01 unknown knowns&lt;br /&gt;
* 00 unknown unknowns&lt;br /&gt;
* and maybe a stray falling outside the matrix: 0x unknown whether known or unknown&lt;br /&gt;
&lt;br /&gt;
These categories are relative. &lt;br /&gt;
What is an unknown known for group A can be a known known for group B.&lt;br /&gt;
&lt;br /&gt;
== Relation to APM ==&lt;br /&gt;
&lt;br /&gt;
When it comes to knowledge about [[Main Page|APM]] and&lt;br /&gt;
if one looks at society as a hole or more narrowly even&lt;br /&gt;
if one looks only at experts in fields that are thematically near to APM  &lt;br /&gt;
then currently (2018) there&amp;#039;s a lot of of knowledge that is not present in both public and expert awareness.&lt;br /&gt;
We have the situation 01: unknown knowns.&lt;br /&gt;
&lt;br /&gt;
These unknown knowns can make it very difficult for someone knowing these unknown knowns&lt;br /&gt;
to have productive discussions.&lt;br /&gt;
In particular if many/most of the known knowns for the presenter are still unknown knowns in the audience   &lt;br /&gt;
it is difficult to point efforts towards 10 the known unknowns that need to be resolved to have progress&lt;br /&gt;
beyond the current state.&lt;br /&gt;
&lt;br /&gt;
In this situation it is important to first focus making the unknown knowns to known knowns &lt;br /&gt;
before going on discussing the known unknowns.&lt;br /&gt;
(Progress in perception).&lt;br /&gt;

The buildability knowability matrix:&lt;br /&gt;
* buildable and knowable (regime of well understood engineering)&lt;br /&gt;
* buildable and not knowable (&amp;quot;black magic&amp;quot; technology that works by lucky accident and no one has any clue how to improve it)&lt;br /&gt;
* not buildable and knowable (regime of results of [[exploratory engineering]])&lt;br /&gt;
* not buildable and not knowable (regime of technology that physics allows but of which we don&amp;#039;t know of)&lt;br /&gt;
