The World is changing faster than our Nudges
Rising crime in cities like London. Obesity that requires far more than reducing sugar by default. The surge of e-cigarettes and vapes contributing to plastic pollution. Overproduction. Accelerating climate crises. These aren’t problems a gentle nudge can fix. They’re structural, systemic, historically layered issues. And my mind doesn’t stay still, it keeps circling the thought: is a nudge enough for the world we’re in now? Or do we desperately need approaches that centre communities, listen to their lived realities and address root causes rather than symptoms?
Everything I read eventually loops me back to the Global South, often Africa too. Not because I’m unaware of what’s unfolding here in the UK (after all, climate change is borderless) but because I imagine what even the basics of behavioural insights would look like if implemented in places like Pakistan. Better infrastructure, safer transport, access to education, stable governance, functioning social services; if those foundations were stronger, even the simplest behavioural interventions would land differently. The baseline reality of people’s lives shapes the way any nudge is received, lived or ignored.
And then there’s something that has stayed with me for months: the phenomenon of “Monsoon Brides.”
For someone sitting comfortably in a Western context, a flood is a natural disaster. For communities back home, a flood is a social disaster. During intense monsoon seasons in Pakistan, when entire villages drown, families lose homes, livestock, crops and any sense of financial control. In that desperation, some families marry off their young daughters as a survival strategy: one less mouth to feed, one potential source of financial relief, one way to secure temporary stability.
A monsoon becomes a marriage.
A climate event becomes a lifetime consequence.
It’s the kind of thing that makes you stop. Because for the world, this is “climate change.” But for that girl, it’s her life. Her education lost. Her autonomy surrendered. Her childhood gone. Her future realigned around a decision forced by floodwater.

How do you nudge your way out of that?
This is what made me pick up Inside the Nudge Unit by David Halpern over the weekend. The book is an engaging and fascinating read, learning how the Behavioural Insights Team came to life experimentally, almost skeptically and how they’ve influenced public policy through tiny behavioural tweaks is incredible. Subtle changes in choice architecture can shift decisions on a national, sometimes global scale.
And yet, as I read, the tension I felt persisted: nudges are brilliant, yes, but they don’t feel like answers to the bigger, heavier problems I see around the world. I’m not against nudges at all [I’m just thinking beyond them, and I’ll still be reading more books on this btw :) ].
So yes, behavioural tweaks are powerful. But they cannot replace systemic change. They cannot substitute for participatory approaches that actually engage the people whose lives are most affected. Nudges can guide choice but we need structural transformation to create choices.
Maybe that’s the real takeaway: small changes are powerful, but they are not enough for a world collapsing under the weight of big problems. We need more imagination, more empathy, more courage and definitely more listening, if we genuinely want solutions that work for everyone, not just those with the luxury of stability.
