[LI] A 4-sphere Venn?; mythical retention data graphic

Two items posted to LinkedIn in late April 2018, on how concepts and data may be presented. The first takes another look at a problem and solutions of a 4-circle Venn diagram as used in the popular ikigai illustration. The issue is displaying all possible overlaps, which is accomplished either by a special arrangement of four ellipses or potentially with 4 spheres in 3D (this was mentioned in passing in the article, but brought to the fore on the occasion of “International Chart Day”). The second highlights a graphic with bogus data which has, in various forms, been widely shared and even cited.

A gentle critique & constructive misuse of the ‘ikigai’ meme,” Don Osborn, LinkedIn.com, 22 April 2018 (posted 26 April 2018)

Since it’s still #InternationalChartDay, will take the opportunity to re-up this discussion of the popular #ikigai #Venn. Note that w/ 4 circles, special arrangement necessary to get all combinations. Or 3D w/ 4 spheres. Can one have a 3D infographic?

Mythical Retention Data & The Corrupted Cone,” Work-Learning Research, 5 January 2015 (posted 28 April 2018)

An interesting caution re sharing infographics w/ data. Popular “memed” versions of the “cone of experience” – how much we retain from different forms of learning – turn out *not* to be supported by research.

(my comment)

Back story is that I was going to use this popular “people remember X% of what they hear, Y% of…” and was looking for the source. Glad I did. Now back to the drawing board…
