New in April

The latest delibaration on system thinking tools, The Ladder of Interference, did not make the cut in April, but it is there, so you can have a look if you want. I used the ladder to evaluate a buying decision and I surprised myself with the conclusion I came up with.

We did finish a lesson on Kellert’s nature-related values typology, to which we added one more ourselves.


We were inspired to write this lesson after reading an article about Kellert’s typology in a Dutch online research journalism magazine, De Correspondent. Needless to say the lesson is in Dutch, but should you be interested in a translation in English, send an email to Central to the lesson is the question “How do we value nature?”, and “How do Kellert’s nature-related values align with economic thinking?” We think these questions can make an interesting classroom discussion.
