Alle 56 artikelen uit de Stubborn Optimist-reeks. Elk artikel stelt een vraag: waar heeft iemand dit probleem al opgelost? En wat vertelt de gedragswetenschap ons over waarom het werkte?
Elk artikel pakt een hardnekkig probleem op en gaat op zoek naar de plek in de wereld waar iemand het al heeft opgelost. En wat de gedragswetenschap ons vertelt over waarom het werkte.
Dit is de blogreeks die ik al jaren in mijn hoofd had: een echte zoektocht, geen inspiratiecontent. Elk artikel is een vraag: waar heeft iemand dit al opgelost? En wat zegt dat over hoe gedrag echt werkt, en hoe je het kunt ontwerpen?
Achter al die vragen zit dezelfde overtuiging: gedrag is een ontwerpkeuze. En iedereen die die overtuiging deelt, kan leren er iets mee te doen.
