# 27 Are co-design and nudge theory friends or foes - with Colette Einfeld

<p>A cracker today with <a href="https://coletteeinfeld.com/">Colette Einfeld</a>, an expert in public policy and in particular &ldquo;nudge policy&rdquo;. Colette is days away from a finished PhD that examines how knowledge is used in nudge and behavioural insights. Nudge theory or policy, if you haven&rsquo;t heard of it, is a concept from behavioural economics, political theory and the broader behavioural science that we can harness human cognitive processes and biases to shape a group or individuals behaviour for public policy purposes. It&rsquo;s become a big deal in public policy. But so has co-design, the idea that you use design methodologies to develop policies, services and systems <em>with</em> the people who are most affected by those policies, services and systems. The reason I reached out to Colette is that they have co-authored a very influential paper (with <a href="https://www.emmablomkamp.com/about">Emma Blomkamp</a>) looking at the relationship between these ideas of nudge and co-design. Do they work together, or against one another? Let&rsquo;s find out.</p> <p>Shownotes:</p> <p>The academic article from Colette and Emma Blomkamp Blomkamp:&nbsp;<a href="https://www.tandfonline.com/doi/abs/10.1080/01442872.2021.1879036#:~:text=Nudge%20is%20an%20approach%20to,to%20respond%20to%20shared%20problems">https://www.tandfonline.com/doi/abs/10.1080/01442872.2021.1879036#:~:text=Nudge%20is%20an%20approach%20to,to%20respond%20to%20shared%20problems</a>.</p> <p>A blog by Colette and Emma:&nbsp;<a href="https://blogs.lse.ac.uk/impactofsocialsciences/2021/07/22/the-incompatibility-of-nudge-and-co-design-as-tools-for-policymaking/">https://blogs.lse.ac.uk/impactofsocialsciences/2021/07/22/the-incompatibility-of-nudge-and-co-design-as-tools-for-policymaking/</a>&nbsp;</p>
