I want to write a book just so i can use this as the title!
If we take seriously the notion that abduction is somewhere at the core of the defining features of Design thinking, then the design act is “shot through” with acts of guessing. Don’t blame me – blame C.S. Pierce for pointing this out. But also be very clear that guessing well is no mean feat. In fact
a) it’s the source of every original human thought
b) it can be developed into a very, very skilful mode of thinking – check out the work of Frank Ghery if you want to see a contemporary master of the guessing process.
