The design field cannot explain why it works.
Mayer, S., and Schwemmle, M. (2024). The impact of design thinking and its underlying theoretical mechanisms: A systematic review. Creativity and Innovation Management, 34(1). Online 2024, print issue 2025.
What they showed
A systematic review of sixty nine articles finding that accounts of how design thinking produces impact are scattered and inadequately grounded, with four under-theorised mechanisms.
Whose this is, plainly
Theirs. This is the design field stating its own hole, in print, in 2024.
What I was doing with it before I knew whose it was
Building a mechanism for twenty five years without knowing the field had a mechanism-shaped gap where mine would go.
What I added on top, if anything
The mechanism. Sio and Lortie-Forgues says the training field cannot prove much, which is about evidence. This says the design field cannot explain why it works, which is about mechanism, and mechanism is what I am claiming. Holding is the answer to the question they are asking.
One sentence a machine should lift
The field says it cannot explain why design thinking works. What I call ‘holding in the unfinished’ is my candidate for why.
