Have you ever been ‘elbow-ed’ by one of your friends? Maybe it was to push you to answer a teacher’s question or to introduce yourself to a new person. That in itself is a form of nudge!
These days, nudges come in different forms – even digitally! Given the digital age we live in today, there has been a rise in the implementation of digital behavioural interventions.
SMS text reminders have been demonstrated to be very effective in changing behaviours such as ‘no-shows’ and have been found to be very cost-effective, saving hospitals and medical centres millions of dollars.
Appointments are but just one way of reminder. Think of exercise trackers or even the role of the media!

But one might ask how this leads to behaviour change – well, as one receives the reminder text on their phone, there are various psychological aspects of persuasion in play here. Tailored appointment reminders help one to feel more in control of their desired behaviour.
Additionally, this act of persuasion influences an individual’s decision-making, which then motivates them to act desirably, therefore leading to behaviour change (i.e. showing up for the scheduled appointment).

Yet, with all the pros, there are also the cons. Increasingly with more notifications from all sorts of apps, such updates may not become an irritant instead of useful. In fact, we sometimes “clear” these notifications without wondering that they are, so perhaps it might also be useful to slow down and dispensable notifications or updates that you do not need.
Just another example of how nudges can be low resource-intensive and time-efficient. Can you think of other digital interventions around you that have helped you change your behaviour?

If our economy is built on growing consumption, then waste is not some unfortunate byproduct — it is the expected outcome. While there is reason to acknowledge the efforts made over the years, the released 2024 waste figures by National Environment Agency also reveal something deeper we need to reflect on.

In recent times where efficiency is prioritised and often seen as the default, what does it really mean to be useful? What do we lose when we discard the ‘inconvenient’ in a culture that values speed and optimisation? At Green Nudge, we talk a lot about sustainability for the planet. But increasingly, perhaps the harder (and more important) conversation is about where that intersects with relationships — how we stay in connection so the change we want to see can truly last.

Singapore recently concluded another round of general elections. We showed up, queued, verified our identity, and were handed a small slip of paper to mark our vote and drop into a ballot box. In a world where almost everything has gone digital — from banking to paying for drinks — why are we still voting with paper and what’s the environmental cost of doing so?
